6-2. Output Functions 

Function: When the MAIN OUTPUT key is turned on the channel with its OUTPUT SELECT LED lit 

is turned on.     

 

 

CAUTION

Make sure that wires are connected with the output terminals firmly before pressing the 

MAIN OUTPUT key.

 

 

 

6-2-1. Method of turning on or off the output with the MAIN OUTPUT key 

Operation procedures 

1. When the OUTPUT SELECT key is pressed, the lamp lights green. 

2. Turn on the MAIN OUTPUT key.    The output is turned on. 

3. When the MAIN OUTPUT key is pressed again, the key goes out and the outputs of all channels 

are turned off. 

 

6-2-2. Method of turning on or off the output with the OUTPUT SELECT key 

  If  the  off  OUTPUT  SELECT  key  is  pressed  while  the  MAIN  OUTPUT  key  is  on,  the  output  is 

turned on.    The lamp is lit in green in the CV operation mode or in red in the CC operation mode. 

  If an OUTPUT SELECT key that is lit in green (or red) is pressed while the MAIN OUTPUT key is 

on, the LED of the pressed key goes out and the channel of that LED is turned off.   

 

6-3. Memory Function 

Function: It is possible to store the set voltage and current and recall them.    The set voltage and 

current values are stored in PRESET.    It is also possible to store the key settings when 

power is turned on. 

<Precautions> 

  It  takes  approximately  0.3  seconds  to  store  the  set  voltage  and  current  in  the  preset  memory.   

Operations of all keys, rotary encoder and external contact control are disabled in this period.
