3.2.1 True RMS Zero Input Characteristic
3.2.1.1 For measuring non-sinusoidal wave signal,
uses true RMS measuring method, which has
less error than traditional average response
measuring method.
3.2.1.2 The true RMS meter can accurately measure
non-sinusoidal wave signal, but if it is in AC
function mode, when there is no signal to be

(3) Press Hz/% key to switch to frequency measuring
state.
(4) Rad the current value on the LCD display.
(5) Pressing Hz/% again can enter duty ratio measuring
state.
1) Clamp head measuring frequency
(through AC current):
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. If the
frequency to be tested is less than 10Hz, or if
frequency is higher than 10 kHz, accuracy is not
guaranteed.
(3) Duty ratio measuring range is 10 ~ 95%.
(4) “ ”means that maximum input current is
1000A AC (RMS).

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.

Electric shock hazard.
Remove the probe from the meter before
measuring with current clamp.
Warning
(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) Rad the current value on the LCD display.

4.17 NCV Measurement
1) Turn the meter to NCV mode.
2) Place the meter top close to the conductor. When
test voltage is greater than 110 Vac (RMS), when the
meter is close to the conductor, the meter induction
voltage indicator will turn on and the buzzer will give
an alternating high-low alarm sound.
1: Even there is no indication, voltage may exist still.
Don't use non-contact voltage detector to judge
whether there is voltage in the wire. Detection
operation could be affected by socket design,
insulation thickness, type and other factors.
2: When inputting voltage on the meter input terminal,
due to the existence of the induced voltage, voltage
induction indicator also may light.
3: External sources of interference (such as flashlight,
motor, etc.) may incorrectly trigger non-contact
voltage detection.
Note:
5. Maintenance
5.1 Replace Battery
Before opening the meter battery cover, remove
probe from the circuit to be measured to avoid
electric shock.
Warning
1) When the battery symbol “ ” appears, the battery
should be replaced immediately.
2) Unscrew the fastening screw of the battery cover
and remove the cover.
3) Replace battery.
4) Put the battery cover back as before.
The battery polarity can't be reversed.
Note:
5.2 Replace Probe
When replacing probe, replaceit with another
identical probe or one with the same level of
performance. The probe should be in good
condition. Probe level: 1000V, 10A.
Warning
If the probe is damaged, such as naked metal wire,
replace the probe.
