4) OPERATION
CAUTION:
Before and after hazardous voltage measurements, test the voltage
function on a known source such as line voltage to determine proper meter functioning.
DC Voltage, AC Voltage, Hz Frequency functions
Set slide-switch to Voltage function position. Inputs are made through the test leads
terminals. For Models 063 & 065, slide-switch on defaults at AC
voltage. Press
SELECT
button momentarily to select DC voltage. For Models 061& 062, separate
ACV & DCV slide-switch positions are being used.
Press the Hz button momentarily to activate Hz Frequency. The Hz trigger level is
determined by the selected function-range from where the Hz function is activated. In
ACV function, activating the Hz function during significant measurements can get the
most appropriate trigger level to avoid electrical noises in most cases. Electrical noise
may cause unstable Hz reading. Activating the Hz function at AC 4.000V range (before
making significant measurements) can get lower trigger level (higher sensitivity). Hz
reading may show zero when the sensitivity is insufficient.
