MICROCONTROLLER
 
The  Multimeter  or  the  Calibrator  functions  can  be  selected  with  sliding  switches.  The  settings  and  the 
parameters are stored in internal memory. The instrument can be software calibrated via the keyboard.  
 
Keyboard: 

The keys have to be pressed at least for 0.5 sec in order to permit the controller to accept 
the command. 

Rate:   

1 sample per 1 sec. 

Memory: 

EEPROM. 

 
SUPPLY 
Battery: 

Two 3.7V-2000mAh rechargeable Li-ion Batteries permit an uninterrupted operation of  
9 hours with 20mA set at the calibrator output. 

Charger: 

Mains voltage 100-240V, 48-60Hz / 12V-600mA DC. The battery requires 4.0 hours to be  
fully charged. The green LED stops flashing. 

 

 
 

 

The calibrator output and the multimeter inputs have common GND. 

ATTENTION! 

In the Current Sink Mode the switches SNK-I and OUT-I have to be selected. Do not switch to OUT-V
The Current and the Voltage Outputs might be destroyed! 

 
The specifications are valid after  
a warm-up time of 10 min. and an 
ambient temperature of 23 ºC±2 ºC
