(Max. rated input voltage: 500 mV dc/ac)
・
AC Voltage (m
), Decibel (dBm) / Frequency (Hz)
simultaneous measurement
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.
WARNING
1) What to measure
・
m (AC voltage): Sine wave AC voltage lower than 600 mV such
as output from a low-frequency amplifier.
・
Hz(Frequency): Frequency on the above circuit
2) Measuring ranges
・
m : 500.00 mV (fixed)
・
Hz: 10.00 Hz
~
200.0 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 function you want to
perform.
④
Apply the test pins (Red and Black) to the object to measure.
⑤
Read the display.
Indicaion in dBm:
After pressing the SELECT button to change the function to the
dBm measurement from the ACV measurement, and after turning
on the power of this multimeter, the latest reference impedance will
be displayed before displaying the dBm readings. Press
dBm-Ω
(RANGE) button to select different reference impedance of 4, 8,
16, 32, 50, 75, 93, 110, 125, 135, 150, 200, 250, 300, 500, 600, 800,
900, 1000, up to 1200 Ω.
