Certified CE Mark for EMC proofing, non interferrence and non effected.
LVD certified for Low Voltage Device.

Use of 4-20 mA simulation has automatic step function every 25% of scale in every 5 seconds.
XMT is used as current drain for the Process signal of 4-20mA connected in series with loop supply.
Frequency simulation is used to simulated the speed of a non-contact speed sensor.
The Thermocouple sinulation is in dual scale readings of temperature and mV displays at the same time.
The RTD simulation for PT100 sensor has dual scale readings as well, one displays the resistance and one the temperature.

The worst scenario error is 0.2% of reading, and this multifunction calibrator is nicknamed the shipboard instrument/electrician tool.

Fuse protection for the low resistance circuits to prevent damages.
