4.5. PE current during operation and touch leakage current

The ESC 2051 is equipped with electronic checking of excessive leakage current. Test
of leakage current is done before start of measurement. If leakage current should
exceed appointed limit, the measurement will not start and message „>10 mA !!" is
displayed. Audible warning signal is generated, too.
The value of leakage current is also compared with appointed limit during
measurement. If leakage current exceeds appointed limit (about 10 mA), the
measurement is finished, message „>10 mA !!" is displayed and audible warning
signal is generated.

4.5.1. Protective class I equipments equipped with mains plug

Firstly test earth bond (chapter 4.1.) and also insulation resistance (chapter
•
4.3.), if it is possible. Then you can execute PE current during operation
measurement.
Take into consideration all safety warnings!
•
Equipment under test must be isolated from ground (from the earth potential)
•
during measurement!
