I watched a video where Dave checks the voltage and current accuracy of his DP832 and I thought I'd do the same with mine. I made a tables as follows:
For Voltage --> 1mV, 3mV, 10mV, 30mV, 100mV, 300mV, 1V, 3V, 10V and 30V for CH1 and CH2 but on CH3 I went to 5V after the 3V setting. For Current --> 1mA, 3mA, 10mA, 30mA, 100mA, 300mA, 1A and 3A.
So, using a 5.5 digit DMM as a reference I found that the max deviation between setpoint and actual reading for the voltage on CH1 was 2mv for just one setting and mostly 0mv or 1mv error for the other settings -- so, not too bad. The deviation between setpoint and DP832 reading was mostly 7mV with a couple readings that differed by 5mV. For Current CH1 was off at most 1mA difference between setpoint and actual while the readings on the DP832 were off by at most 2mA with all other readings with a 1mA error.
For channel 2 things got a bit worse with the actual deviation being between 3mV and 7mV and the readings off by 1mV at best to 11mV. For current the deviation was almost all 0mA with one reading at 1mA. The current reading on the 832 was off by 1mA at all settings.
Channel 3 was a max of 2mV and 2mA off between setpoint and actual while the display error was mostly 1mV with one reading of 2mV but the current was as much as 4mA off on the display.
So, the question I have is ... is there any adjustments for the DP832? For CH1 the actual volts and current are within 2mV and 1mA so no worries there, but the voltage readback on the 832 was off by nominally 7mV and I'd like to be able to adjust that if I could. For CH2 the actual voltage deviated by a nominal 6mV and the readback was off, in the same direction, by an average of 8mV and I'd like to be able to adjust both the actual values as well as the readback. The current readings were all within 1mA so nothing to get upset about there. Lastly, CH3's voltage actual's and readback's were all within 2mV so nothing there, but the current readbacks were off a bit so maybe a tweak there.
I attached a jpeg showing the complete table.
