  Resistor Mode 
 
Pin 23 and Pin 13 ( GND wire) can be connected to a resistor for setting the 
output voltage value of the power supply. 
 
 
To set the 0~5V/0~10V or 0~5KΩ/0~10KΩexternal analog setting range, open 
the MENU (  Menu)  →  CONFIG  (  Configure)  →  Ext-Ctrl  (  External Analog 
Control).
 Press the Right Key to select Voltage( or Resistance). 
Press the Right Key to select 5V/10V or 5KΩ/10KΩ within the full scale scope. 
Voltage monitoring 
This function enables monitoring of voltage output via Pin 24 or the GND pin 
( i.e., Pin 13), which can be connected to a digital voltmeter ( DVM). To use this 
function, the output control should be under the external analog control mode. 
The output voltage monitoring range ( which reflects the power supply output 
voltage from zero to full scale) can be selected from 0-10V or 0-5V. To switch on 
the monitoring range setting, open the MENU ( Menu) → CONFIG ( Configure) 
→ Monitor ( External monitor mode). Press the Right Key to select Voltage( or 
Resistance).   
Press the Right Key to select the output voltage monitoring range ( 0~10V or 
0~5V). 
The connection setting of digital voltmeter is shown below. 
 
 
Current monitoring 
This function enables monitoring of current output via Pin 25 or the GND pin 
( i.e., Pin 13), which can be connected to a digital voltmeter ( DVM). To use this
