Current setting/measurement adjustment (channel L):
Set the DC source to 5V/2.1A and current shunt range to 2A.
Set channel L to CCL mode and program the current to 2A.
Adjust VRB1 on board L until shunt current = 1.999 to 2.001A.
Adjust VRB3 on board L until display current = 1.999 to 2.001A.
Set the DC source to 5V/21A and current shunt range to 20A.
Set channel L to CCH mode and program the current to 20A.
Adjust VRB5 on board L until shunt current = 19.99 to 20.01A.
Adjust VRB7 on board L until display current = 19.99 to 20.01A.
CR mode adjustment (channel L):
Set the DC source to 15V and current limit to 10A.
Set channel L to CRL mode and program resistance to 3 ohms.
Adjust VRB1 on board A until DMM (V) reading/3 ohms = shunt current
±
2mA.
CV mode adjustment (channel L):
Select CV mode of channel L and program CV voltage to 76V.
Set current limit of CV mode to 1A in configuration.
Set the DC source to 80V/0.1A.
Adjust VRB2 on board A until DMM (V) reading = 75.997 to 76.003V.
Voltage measurement adjustment (channel R):
Set channel R of the load module to CRH mode.
Apply DC source to the input terminals of channel R and set the DC source to 80V/0.1A.
Adjust VRA9 on board L until the display of voltage in channel R = DMM (V) reading
±
0.01V.
Current offset adjustment (channel R):
Set the DC source to 5V/200mA and current shunt range to 20mA.
Set channel R to CCL mode and program the current to 2mA.
Adjust VRA2 on board L until shunt current = 1.95 to 2.05mA.
Set channel R to CCH mode and program the current to 20mA.
Adjust VRA6 on board L until shunt current = 19.8 to 20.2mA.
