I ADC Calibration

1. Make sure that DP800 has been warmed up for at least 30 minutes. Connect the
channel output terminals (take CH1 as an example; the calibration method is
also applicable to CH2 and CH3) of DP800 with the current input terminals of the
digital multimeter using the test leads as shown in Figure 2-3.
Press the On/Off softkey corresponding to CH1 at the front panel of DP800 to

enable the channel output.
3. Turn on the digital multimeter. Select the DC current (DCI) measurement
function; set the range to "Auto" and the scale to "A".
4. Enter the DP800 calibration interface. Press Cal Item  I ADC 
the cursor switches to the first point in the ID column.
5. Press Meas Val and the Meas Value column of the point selected becomes
editable. At this point, use the numeric keyboard or the knob and direction keys
to input the current measurement value of the digital multimeter (please set the
"Sign" to be "+" or "-" according to the sign of the measurement value).
Press Input Val to write the measurement value into the system and finish the

calibration of the point currently selected. The cursor switches to the ID column.
Note: Please wait for at least 3 seconds before pressing Input Val after
inputting the current measurement value of the digital multimeter. Otherwise
