 The [[https://git.cuvoodoo.info/kingkevin/ea-ps_2084-03b/blob/master/control.rb|control]] programming will increment the voltage from 0 to 84 V in 0.1 V steps, at 1.0 A.
-It will set the voltage and current which are set, actual (measured by the power supply), and [[#mutli-meter|measured]] (measured by the DMM)

 To measure the output of the power supply I used two [[http://uni-trend.com/UT61E.html|UNI-T UT61E]].
-These are good multimeters for electronics which you can get [[http://www.aliexpress.com/wholesale?catId=0&SearchText=uni-t+ut61e|quite cheap]], with 22000 counts, and offer connection to the PC.

 More details about the cable and modification is described in this picture:
+For the second multimeter I used a [[http://www.uni-trend.com/en/product/2014_0626_555.html|UT-D04]] USB cable.
+This time the data doesn't come over a serial port, but rather a HID device.
+==== communication ====
+To read the data from both multimeter I used [[http://sigrok.org/|sirgork]].
+It supports the [[http://sigrok.org/wiki/UNI-T_UT61E|UNI-T UT61E]] and [[http://sigrok.org/wiki/Device_cables#UNI-T_UT-D02|both]] [[http://sigrok.org/wiki/Device_cables#UNI-T_UT-D04|cables]].
+Once [[http://sigrok.org/wiki/Sigrok-cli|sigrok-cli]] installed you can record the data using the following command:
+<code>
+sigrok-cli --driver uni-t-ut61e-ser:conn=/dev/ttyUSB0 --samples 1 -O analog
+</code>
+or
+<code>
+sigrok-cli --driver uni-t-ut61e:conn=1a86.e008 --samples 1 -O analog
+</code>
+depending on the cable.
