1) What to measure
・
(ACV): Sine wave voltages such as output from a wall socket.
・
Hz (Frequency): Frequency on a AC circuit.
2) Measuring ranges
・
: 9.999 V, 99.9 V, and 999.9 V
・
Hz: 15.00 Hz to 10.00 kHz (Auto ranging)
3) Measuring procedure
①
Connect the red plug of the test lead to the VHz measuring
terminal and the black one to the COM terminal.
②
Set the function selector to .
③
Press the SELECT button to select a display style.
④
Apply the test pins (Red and Black) to the object to measure.
⑤
Read the display.
1. Do not apply any input signal exceeding the max. rated input
voltage.
2. Do not switch the function selector while measuring.
3. Keep your fingers behind the finger guards of the test leads
while measurement.

‡ AC Voltage ( )/Frequency (Hz) Simultaneous Measurement
Note:
Hz input sensitivity varies automatically with a selected voltage
range. 9.999 V range has the highest sensitivity and the 999.9 V
range has the lowest sensitivity. Auto ranging measurements
normally set the most appropriate trigger level. You can also press
the RANGE HOLD button to select another trigger level (voltage
range) manually.
If the Hz reading becomes unstable, select higher voltage range
to avoid electrical noise. If the reading shows zero, select lower
voltage range.
