The '''Voltcraft VC-350e''' is a 4000 counts, CAT II (750/1000V) handheld digital multimeter with RS232 connectivity.<br />
<br />
It is an OEM version of the Saftec SAF350E. The device was sold by ''Conrad Elektronik'' as article 125512 around 1997 and is not available any more.<br />

== Serial protocol ==<br />
<br />
To test on a Linux computer using the screen command, open a terminal like xfce4-terminal, gnome-terminal or xterm and start a session, we will use this terminal to display the data coming from the multimeter:<br />
<br />
<pre><br />
/usr/bin/screen -d -m -S serial /dev/ttyUSB0 1200<br />
screen -r serial<br />
</pre><br />
<br />
Then open a new terminal to send commands to the multimeter, example to read the current measurements:<br />
<br />
<pre><br />
screen -S serial -X stuff "$(echo -e '\xE0\xFF\r')"<br />
</pre><br />
<br />
Output something like "012.003 V". Often the units show garbled, aka you will see "012.003 �" or something especially when using Ohms. I remember I also had this with the original vendor software (which I no longer have). So maybe my device is poor or it was just never developed better.<br />
<br />
Taken from the manual found at [https://www.elektroda.pl/rtvforum/topic2740476.html#13475581 elektroda.pl]. <br />
<br />
The following commands can be send over RS-232:<br />
<br />
{| border="0" style="font-size: smaller;" class="alternategrey sigroktable"<br />
|C0<br />

|-<br />

To test on a Linux computer using the screen command, open a terminal like xfce4-terminal, gnome-terminal or xterm and start a session, we will use this terminal to display the data coming from the multimeter:<br />
<br />
<pre><br />
/usr/bin/screen -d -m -S serial /dev/ttyUSB0 1200<br />
screen -r serial<br />
</pre><br />
<br />
Then open a new terminal to send commands to the multimeter, example to read the current measurements:<br />
<br />
<pre><br />
screen -S serial -X stuff "$(echo -e '\xE0\xFF\r')"<br />
</pre><br />
<br />
Output something like "012.003 V". Often the units show garbled, aka you will see "012.003 �" or something especially when using Ohms. I remember I also had this with the original vendor software (which I no longer have). So maybe my device is poor or it was just never developed better.<br />

The '''Voltcraft VC-350e''' is a 4000 counts, CAT II (750/1000V) handheld digital multimeter with RS232 connectivity.<br />
<br />
It is an OEM version of the Saftec SAF350E. The device was sold by ''Conrad Elektronik'' as article 125512 around 1997 and is not available any more.<br />

To test on a Linux computer using the screen command, open a terminal like xfce4-terminal, gnome-terminal or xterm and start a session, we will use this terminal to display the data coming from the multimeter:<br />
<br />
<pre><br />
/usr/bin/screen -d -m -S serial /dev/ttyUSB0 1200<br />
screen -r serial<br />
</pre><br />
<br />
Then open a new terminal to send commands to the multimeter, example to read the current measurements:<br />
<br />
<pre><br />
screen -S serial -X stuff "$(echo -e '\xE0\xFF\r')"<br />
</pre><br />
<br />
Output something like "012.003 V". Often the units show garbled, aka you will see "012.003 �" or something especially when using Ohms. I remember I also had this with the original vendor software (which I no longer have). So maybe my device is poor or it was just never developed better.<br />

The '''Voltcraft VC-350e''' is a 4000 counts, CAT II (750/1000V) handheld digital multimeter with RS232 connectivity.<br />
<br />
It is an OEM version of the Saftec SAF350E. The device was sold by ''Conrad Elektronik'' as article 125512 around 1997 and is not available any more.<br />

To test on a Linux computer using the screen command, open a terminal like xfce4-terminal, gnome-terminal or xterm and start a session, we will use this terminal to display the data coming from the multimeter:<br />
<br />
<code><br />
/usr/bin/screen -d -m -S serial /dev/ttyUSB0 1200<br />
screen -r serial<br />
</code><br />
<br />
Then open a new terminal to send commands to the multimeter, example to read the current measurements:<br />
<br />
<code><br />
screen -S serial -X stuff "$(echo -e '\xE0\xFF\r')"<br />
</code><br />
<br />
Output something like "012.003 V". Often the units show garbled, aka you will see "012.003 �" or something especially when using Ohms. I remember I also had this with the original vendor software (which I no longer have). So maybe my device is poor or it was just never developed better.<br />

== Serial protocol ==<br />
<br />
To test on a Linux computer using the screen command, open a terminal like xfce4-terminal, gnome-terminal or xterm and start a session, we will use this terminal to display the data coming from the multimeter:<br />
<br />
<code><br />
/usr/bin/screen -d -m -S serial /dev/ttyUSB0 1200<br />
<br />
screen -r serial<br />
</code><br />
<br />
Then open a new terminal to send commands to the multimeter, example to read the current measurements:<br />
<br />
<code><br />
screen -S serial -X stuff "$(echo -e '\xE0\xFF\r')"<br />
</code><br />
<br />
Output something like "012.003 V". Often the units show garbled, aka you will see "012.003 �" or something especially when using Ohms. I remember I also had this with the original vendor software (which I no longer have). So maybe my device is poor or it was just never developed better.<br />

The column "sigrok result" contains in short form what the driver generates for the resp. data type.<br />
<br />
The device seems to be extremely slow when the RS-232 interface is enabled and often takes up to about 10 seconds to detect a changed value or switch to another range. During this time a previous value keeps being sent. When changing to a new range automatically or manually, the device might send the old value scaled to the new range for a short time. This behaviour is caused by the device, not by sigrok! It improves slightly in manual range.<br />

The column "sigrok result" contains in short form what the driver generates for the resp. data type.<br />
<br />
The device seems to be extremely slow when the RS-232 interface is enabled and often takes up to about 10 seconds to detect a changed value or switch to another range. During this time a previous value keeps being sent. When changing to a new range automatically or manually, the device might send the old value scaled to the new range for a short time. This behaviour is caused by the device, not by sigrok! It improves slightly in manual range.<br />

The '''Voltcraft VC-350e''' is a 4000 counts, CAT II (750/1000V) handheld digital multimeter with RS232 connectivity.<br />
<br />
It is an OEM version of the Saftec SAF350E. The device was sold by ''Conrad Elektronik'' as article 125512 around 1997 and is not available any more.<br />

This device uses what looks like a Metex connector, but it only has 4 pins (where 5 pins is seen on other devices).<br />

== Serial protocol ==<br />
<br />
To test on a Linux computer using the screen command, open a terminal like xfce4-terminal, gnome-terminal or xterm and start a session, we will use this terminal to display the data coming from the multimeter:<br />
<br />
<code><br />
/usr/bin/screen -d -m -S serial /dev/ttyUSB0 1200<br />
<br />
screen -r serial<br />
</code><br />
<br />
Then open a new terminal to send commands to the multimeter, example to read the current measurements:<br />
<br />
<code><br />
screen -S serial -X stuff "$(echo -e '\xE0\xFF\r')"<br />
</code><br />
<br />
Output something like "012.003 V". Often the units show garbled, aka you will see "012.003 �" or something especially when using Ohms. I remember I also had this with the original vendor software (which I no longer have). So maybe my device is poor or it was just never developed better.<br />
<br />
== Model family ==<br />
<br />
It seems that this device belongs to a family of several similiar devices and OEM models.<br />

The column "sigrok result" contains in short form what the driver generates for the resp. data type.<br />
<br />
The device seems to be extremely slow when the RS-232 interface is enabled and often takes up to about 10 seconds to detect a changed value or switch to another range. During this time a previous value keeps being sent. When changing to a new range automatically or manually, the device might send the old value scaled to the new range for a short time. This behaviour is caused by the device, not by sigrok! It improves slightly in manual range.<br />

The column "sigrok result" contains in short form what the driver generates for the resp. data type.<br />
<br />
The device seems to be extremely slow when the RS-232 interface is enabled and often takes up to about 10 seconds to detect a changed value or switch to another range. During this time a previous value keeps being sent. When changing to a new range automatically or manually, the device might send the old value scaled to the new range for a short time. This behaviour is caused by the device, not by sigrok! It improves slightly in manual range.<br />

<div>This is an alphabetically ordered table of various [https://en.wikipedia.org/wiki/Multimeter multimeters] which can log data to your PC via USB, RS232, and so on. We do '''not''' list devices without PC logging functionality, as those are not really useful for sigrok.<br />
<br />
This page lists commercial and non-commercial devices with a short overview of their capabilities. We list all kinds of devices here, not only [[Supported_hardware#Multimeters|those supported by sigrok]].<br />

<div>This is an alphabetically ordered table of various [https://en.wikipedia.org/wiki/Multimeter multimeters] which can log data to your PC via USB, RS232, and so on. We do '''not''' list devices without PC logging functionality, as those are not really useful for sigrok.<br />
<br />
This page lists commercial and non-commercial devices with a short overview of their capabilities. We list all kinds of devices here, not only [[Supported_hardware#Multimeters|those supported by sigrok]].<br />
<br />
You should '''not''' use the information here as the sole source for any buying decisions, this is just meant for informational purposes. Please carefully check the vendor websites if you intend to buy any hardware.<br />

<div>This is an alphabetically ordered table of various [https://en.wikipedia.org/wiki/Multimeter multimeters] which can log data to your PC via USB, RS232, and so on. We do '''not''' list devices without PC logging functionality, as those are not really useful for sigrok.<br />
<br />
This page lists commercial and non-commercial devices with a short overview of their capabilities. We list all kinds of devices here, not only [[Supported_hardware#Multimeters|those supported by sigrok]].<br />
<br />
You should '''not''' use the information here as the sole source for any buying decisions, this is just meant for informational purposes. Please carefully check the vendor websites if you intend to buy any hardware.<br />

The column "sigrok result" contains in short form what the driver generates for the resp. data type.<br />
<br />
The device seems to be extremely slow when the RS-232 interface is enabled and often takes up to about 10 seconds to detect a changed value or switch to another range. During this time a previous value keeps being sent. When changing to a new range automatically or manually, the device might send the old value scaled to the new range for a short time. This behaviour is caused by the device, not by sigrok! It improves slightly in manual range.<br />

The column "sigrok result" contains in short form what the driver generates for the resp. data type.<br />
<br />
The device seems to be extremely slow when the RS-232 interface is enabled and often takes up to about 10 seconds to detect a changed value or switch to another range. During this time a previous value keeps being sent. When changing to a new range automatically or manually, the device might send the old value scaled to the new range for a short time. This behaviour is caused by the device, not by sigrok! It improves slightly in manual range.<br />

The column "sigrok result" contains in short form what the driver generates for the resp. data type.<br />
<br />
The device seems to be extremely slow when the RS-232 interface is enabled and often takes up to about 10 seconds to detect a changed value or switch to another range. During this time a previous value keeps being sent. When changing to a new range automatically or manually, the device might send the old value scaled to the new range for a short time. This behaviour is caused by the device, not by sigrok! It improves slightly in manual range.<br />

<div>This is an alphabetically ordered table of various [https://en.wikipedia.org/wiki/Multimeter multimeters] which can log data to your PC via USB, RS232, and so on. We do '''not''' list devices without PC logging functionality, as those are not really useful for sigrok.<br />
<br />
This page lists commercial and non-commercial devices with a short overview of their capabilities. We list all kinds of devices here, not only [[Supported_hardware#Multimeters|those supported by sigrok]].<br />
<br />
You should '''not''' use the information here as the sole source for any buying decisions, this is just meant for informational purposes. Please carefully check the vendor websites if you intend to buy any hardware.<br />
