the sensor produces (transfer error, delay time, ...). So you get the best measuring results with
each sensor.
Due to the EEPROM this sensors offer a plug & play solution for your measuring. The usage
of the LMG sensor input offers several measuring ranges which increase the dynamic of the
connected sensors.
There is a very wide range of sensors available:
•
Current clamps, transformers, hall sensors, flux compensated types, flexible Rogowski
sensors, shunts, ...
•
Accuracies up to <0.01%
•
Frequency range from DC to several hundred kHz
•
Current range from <<1A up to several kA
For the exact specifications of all this sensors you find a detailed manual on the CD which is
delivered together with this manual. If this CD is missing or you have this manual only as PDF
file you can request it via email from ‘sales@zes.com’.
For hints how to connect several sensors to one channel, please refer to chapter 14.1.2.1,
‘Several external sensors in a test bench’.
