surement. The HOLD symbol appears and the mea-
surement is locked.

Second Function: Frequency Selector feature
When high frequencies from equipment such as invert-
ers are presented in the circuit under test, this instrument
measures AC current not just for only 50Hz or 60Hz but
harmonic frequency as well.

measure only the AC current of 50Hz or 60Hz fundamen-
tal frequency, a "high-cut" filter is built in this instrument.
• To activate the Frequency Selector feature, press and
hold down the HOLD button for approx 2 seconds until
the 50/60Hz symbol displays.
• To deactivate, press and hold down the button again
