B. Ac current limit to be checked with Clamp meter (See fig.1 for how to
connect clamp meter)
NOTE:- With load
current can vary
somewhat.
B) Use of Clamp meter for measurement of AC current:-
Clamp meter is used to monitor the AC current taken by AC-DC card/High frequency
Drive.
Connecting Clamp meter to measure AC current:-
1) Put the Clamp meter rotary switch in AC current measuring side at range of
200A (~)
2) Pass “Jaws” of Clamp meter through the live wire which is connected to “L” of AC-
DC card/high frequency drive by pressing the knob as shown in fig.
