4.11 Voltage Measurement

1) Insert black probe to COM jack, insert red probe to INPUT jack,
choose appropriate measuring range.
2) Place rotary switch to AC voltage
meter is in the AC voltage measurement state. To measure DC voltage,
press FUNC button to enter DC voltage measurement state.
3) To measure mV voltage, switch the meter to mV range through the
RANGE key.
4) Connect the probe with voltage source or both ends of load in parallel
for measurement.
5) Read the voltage on the LCD.
Note:
1) In the small voltage measuring range, if the probe is not connected with
the circuit to be tested, the meter may have fluctuating readings. This is
normal and caused by the meter's high sensitivity. When the meter is con-
nected with the circuit to be tested, you will get actual measured value.
4.12 Frequency and Duty Ratio Measurement
1) Insert black probe to COM jack, insert red probe to INPUT jack.
2) Function switch is placed to position HZ.
3) Connect the probe with signal or both ends of load in parallel for
measurement.
Note:
Frequency measurement range is 10Hz~60MHz. If the frequency to be
tested is less than 10Hz, LCD will show "00.0". When measuring
frequencies higher than 60MHz, duty ratio measurement accuracy is not
guaranteed.
