The '''UNI-T UT804''' is a 40000/4000 counts, CAT III (1000V) / CAT IV (600V) benchtop digital multimeter with RS232 and USB connectivity. It can be powered by AC power or by six 1.5V C battery cells.

See [[UNI-T UT71x series]] for information common to all devices in this series.

== Hardware ==

'''Multimeter''':
* '''44000/440000-count dual-slope ADC''': [http://www.cyrustek.com.tw/product-1-44000.htm#ES51966 Cyrustek ES51966P] ([http://www.cyrustek.com.tw/spec/ES51966A.pdf datasheet])
* '''16-bit microcontroller''': [https://www.ti.com/product/MSP430F149 MSP430F149] [https://www.ti.com/lit/ds/symlink/msp430f149.pdf datasheet]

'''RS232 cable:'''
* See [[Device cables#UNI-T_UT-D02]].

'''USB cable:'''
* See [[Device cables#UNI-T_UT-D04]].

== Disassembly ==

There are four screws on the bottom, one of them is captive and does not come out. The red (or grey in the newer revisions) plastic is held on two points top and bottom each. It can be taken off with the help of a flathead screwdriver and pops off easily.

== Usage ==

To receive data from the UT804 via USB the driver and the USB VID/PID of the [[WCH CH9325]] needs to be specified like this:

sigrok-cli -d uni-t-ut804:conn=1a86.e008 --continuous
