range must be selected.
3) " " symbol indicates that máximum input voltage is 1000VDC / 750VAC. Maximum input
voltage at mV is 600mVac/dc
4) If the readings measured by the meter is more than 600VAC(RMS), it will be send out "beep"
alarm.
4.12 Frequency And Duty Ratio Measurement
1) Clamp head measuring frequency (through AC current):
WARNING
Electric shock hazard.
Remove the probe from the meter before measuring 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 during 2 seconds to switch to frequency measuring state.
4) Read the frequency value on the LCD display.
5) Pressing Hz/% again can enter duty ratio measuring state and press for 2 second can return back
to ACA mode.
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 1 kHz, accuracy is not guarantee
3) Duty ratio measuring range is 10 ~ 95%.
4) "
" means that maximum input current is 1000A AC (TRMS).
2) In Voltage Measurement Mode:
WARNING
Electric shock hazard.
Pay special attention to avoid shock when measuring high voltage.
Don't input voltage more than AC750 T-RMS.
1) Insert black probe to COM jack, insert red probe to INPUT jack.
2) Place transfer switch to
state.
3) Press "Hz/%" key during 2 seconds to switch to frequency measuring state.
4) Connect the probe with signal or both ends of load in parallel for measurement.
5) Read on the LCD.
6) Pressing "Hz/%" again can enter duty ratio measurig state and press for 2 second can return
back to ACA mode.
or position, press FUNC to enter AC voltage measurement
