DCRM100B:
|
|
Highly portable, easy to connect and use
|
|
Complete instrument- has internal battery for 100A DC, inbuilt charger
|
|
Four wire method of measurement and 100A DC current injection ensures excellent accuracy and repeatability of results
|
|
|
Possible to measure the length of arcing contact when travel trace is
obtained simultaneously on HISAC
|
|
The test report is generated through HISAC analyser and can be directly
printed out or downloaded to IBM compatible PC for evaluation of
dynamic variation of contact resistance
|
|
Evaluation of parameters is possible using SCOPE's CPLOT software
Works reliably under charged switchyard conditions
