The UNI-T UT61E is a 22000 counts, CAT II (600V) / CAT III (300V) handheld digital multimeter with RS232 or USB connectivity.

See UNI-T UT61E/Info for more details (such as lsusb -vvv output) about the device.

See Multimeter_ICs#Cyrustek ES51922 for the DMM IC protocol.

Depending on the cable, additional decoding is needed, though.

TODO: Serial cable vs. the two USB HID based cables.

The transmission of the measurement data cannot be disabled, the respective Cyrustek ES51922 pin (111, RS232) is tied to GND (i.e. transmission is always enabled) on this multimeter.[1]


The following sigrok-cli command can be used to receive measured values from a device connected via USB (note that the USB VID/PID after the conn option needs to be changed depending on the exact USB adapter cable used):

$ sigrok-cli --driver=uni-t-ut61e:conn=1a86.e008 -O analog

With the --samples <n> option it is posible to stop the acquisition after the specified number of measurements. More information can be found in the README.devices file of the libsigrok source tree.
