button to enter AC voltage measurement state.
• Connect the probe with voltage source or both ends of load in parallel for
measurement.
• Read the voltage on the LCD.
NOTE:
• In the small voltage measuring range, the probe is not connected with the
circuit to be tested, and the meter may have fluctuating readings, which
is normal and caused by the meter's high sensitivity. When the meter is
connected with the circuit to be tested, you will get actual measured value.
• In the relative measurement mode, automatic measuring range is invalid..
• " "indicates that maximum input voltage is 750V AC or 1000V DC. Maxi-
mum input voltage at mode mV is 600mV DC or AC.
• If the readings measured by the meter is more than 750V rms AC, it will send
out "beep" alarm.
4.12 Frequency And Duty Ratio Measurement
Electric shock hazard. Remove the probe from the meter before mea-
suring with current clamp.
• (1) Measuring switch is placed to position A.
• (2) Hold the trigger, open clamp head, clip one lead of measurement circuit
to be tested in the clamp.
• (3) Press Hz/% key to switch to frequency measuring state.
• (4) Read the current value on the LCD display.
• (5) Pressing Hz/% again can enter duty ratio measuring state.
NOTE:
(1) Clamping two or more leads of circuit to be tested simultaneously will not
get the correct measuring results.
(2) Frequency measurement range is 10Hz~1kHz the frequency to be tested
is less than 10Hz, or if frequency is higher than 10 kHz, accuracy is not guar-
antee.
(3) Duty ratio measuring range is 10 ~ 95%.
4) " " means that maximum input current is 1000A AC (RMS).
