4.10 Current Measurement
Electric shock hazard.
Remove the probe from the meter before
measuring with current clamp.
Warning
1) Measuring switch is placed to position A. At this time,
the meter is in AC current measurement state.
Choose appropriate measuring range.
2) If you want to measure DC current, press FUNC
button to enter direct current measurement state.
3) Hold the trigger, open clamp head, clip one lead of
measurement circuit to be tested in the clamp.
4) Read the current value on the LCD display.
Note:
4.11 Voltage Measurement
1) Clamping two or more leads of circuit to be tested
simultaneously will not get the correct measuring
results.
2) To get accurate reading, connect the lead to be
tested at the center of current clamp.
3) “ ”indicates that maximum input AC current is 1000 A.
4) In order to improve the measurement precision, in the
DC current measurement state, if the LCD display is
not zero, press REL back to zero, then measure.
Electric shock hazard.
Pay special attention to avoid shock when
measuring high voltage.
Don't input voltage more than AC750 RMS.
Warning
1) Insert black probe to COM jack, insert red probe to
INPUT jack, choose appropriate measuring range.
2) Place transfer switch to AC voltage or position.
At this time, the meter is in the DC voltage
measurement state. To measure AC voltage, press
FUNC button to enter AC voltage measurement state.
3) Connect the probe with voltage source or both ends
of load in parallel for measurement.
4) Read the voltage on the LCD.
Note:
1) 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.
2) In the relative measurement mode, automatic
measuring range is invalid.
3) “ ”indicates that maximum input voltage is 750V AC
or 1000V DC. Maximum input voltage at mode mV is
600mV DC or AC.
4) If the readings measured by the meter is more than
750V rms AC, it will send out "beep" alarm.
