External Voltage Programming 
Calibration  

 
Follow the steps below to perform the external voltage programming 
calibration: 
 

1.

 

Connect the DMM to the external analog control terminals of 
DB25 connector (+ on the DMM to Pins 9 and 11, - on the DMM 
to Pin 22 (GND)) on the rear of the power supply, as shown in 
the figure below: 
 

 

Figure 5.4 – External Voltage Programming Calibration Diagram 

 

2.

 

Set the DMM to a DC voltage measurement. Select the 

EXT_VOLT parameter in the CAL menu and press 

. The 

following will be displayed:
