Introduction 

This process calibrator/meter is a hand-held, battery-operated instrument for testing and 
troubleshooting power electronic systems. This device can be used not only for instrument 
system maintenance, but also for maintaining, servicing industrial meters, testing electronic 
circuits and electronic equipments. The meter can also be used to measure or calibrate 
sensors or transmitters in automotive or automatic control system. 
 
The meter generates a high precision constant voltage, constant current and square wave 
output and includes a full feature, high accuracy multimeter. The precision source and the 
measurement functions can perform simultaneously.
