For the measurement of sine wave signal, the true RMS measurement method has less
error than the traditional average response method.
The RMS meter can accurately measure the sine wave signal, but if the measured
signal is not input in the AC function (in the AC voltage function, the input terminal is
short-circuited), the clamp meter may display a value between 1 and 50. These devia-
tions are normal. Within the specified measurement range, they will not affect the
accuracy of the meter in measuring AC.
True RMS requires the input signal to reach a certain level before measurement.
Therefore, the range of AC voltage and current is specified between 2% and 100% of
full scale.
In the small voltage range, if the test leads are not connected to the circuit under test, the
meter may have a pulsating reading. This is normal. This is caused by the high sensitivity
of the meter and does not affect the actual measurement result.

In the process of measurement, if you need to hold the data, press the “ ”key,
and the value on the display will be locked. Press this key again to release the data hold.
When the meter is in the AC voltage and AC current range, if you press and hold the “
REL/Hz/%”key for more than 2 seconds, the meter will change to “Hz” measure-
ment, which will measure the frequency of the measured AC voltage and AC current
signal. Press the “REL/Hz/%”key again, and the meter will change to “%” mea-
surement, which will measure the duty cycle of the measured voltage and current
signals.
Press the “MAX MIN” key to enter the manual range mode and display the maxi-
mum value; press this key again to display the minimum value; press this key for the
third time to display the difference between “Max-Peak Min"; Repeat this cycle. Press
the “MAX MIN” key for more than 2 seconds to exit this mode.
After entering the Max mode, the measured maximum value is automatically saved.
After entering the Min mode, the measured minimum value is automatically saved.
After entering the Max-Min mode, the measured difference is automatically saved.
Press the “MAX MIN”key for more than 2 seconds to exit this mode, and then the
instrument is restored to the normal measurement state.
The meter cannot switch to frequency and duty cycle measurement mode in the maxi-
mum/minimum measurement state.

The “RAN” key is an automatic/manual range switch key, which acts in a trigger mode.
When the meter is turned on or the rotary switch is turned, the preset range is auto range.
Click the “RAN” key to switch to manual range. In the manual range mode, each time
you press this key, you will jump one level up, and when you reach the highest level, press
this key again to jump to the lowest level, cycling in turn. Manual range is not set for
frequency and capacitance measurement. If you press the “RAN” key for more than 2
seconds or the rotary switch is switched, the manual range state will be exited.
In the resistance mode, press the“SEL” key to cycle through the four levels of resis-
tance, diode, continuity detection, and capacitance.
In the voltage mode, press the“SEL” key to switch between DC and AC.
In the temperature mode, press the “SEL”key to switch between ℃ and ℉.
The “REL” key is a relative value measurement key, which acts in a trigger mode.
When this key is touched, it enters the relative value measurement mode. The current
displayed value is stored in the memory as a reference value. In future measurement,
the displayed value is the difference between the input value minus the reference
value.
That is, REL△ (current reading) = input value - reference value.
Relative value measurement can only be performed within a certain range, that is to
say, this function is only available in manual measurement mode.
In the process of measurement, if the ambient light is too dark, which makes reading
difficulties, you can press the “ ”key for more than 2 seconds to turn on the
backlight, and it will automatically shut down in about 30 seconds.
After the backlight is turned on, press and hold the “ ” key for more than 2
seconds to turn it off.
In the Current range, the instrument will turn on the clamp head lighting while turning
on the backlight. The luminous body of the backlight is LED, and its working current is
relatively large. Although the meter is set to turn off regularly (the timing time is about
30 seconds), frequent use of the backlight will shorten the battery life. Therefore, in
unnecessary cases, the use of backlight should be minimized.

When the battery voltage ≤ 3.9V, the display shows “ ” (under voltage) symbol. But
in the case of using the backlight, when the battery voltage ≥3.9V, the battery voltage will
drop due to the large working current, and the “ ”symbol may be displayed (when
the “ ”symbol is displayed, the accuracy of the measurement is not guaranteed). At
this time, the battery does not need to be replaced, and it can be used normally without
the backlight source until the“ ”symbol is displayed.
If there is no operation within 15 minutes after starting up, the meter will enter the
sleep state and automatically shut down to save power. 1 minute before shutting
down, the buzzer will give 5 prompts, and it will enter the sleep state after a long sound
before shutting down.
After the auto shutdown, press the “SEL” key, and the meter will resume working
status.
If you press and hold the “SEL” key while powering on, the auto shutdown function
will be cancelled.
When pressing any key or turning the function rotary switch, if the function key is valid,
the buzzer will issue a “Beep” sound (about 0.25 seconds). When the measured voltage
or current is greater than the set alarm value, for example, the AC voltage is greater than
600V, the DC voltage is greater than 600V, or the AC / DC current is greater than 600A, the
buzzer will continue to sound as an over-range warning. About 1 minute before auto shut-
down, the buzzer will emit 5 consecutive warnings, and before shutdown, the buzzer will
emit a long warning; when the automatic shutdown function is cancelled, 5 consecutive
warnings will be emitted every 15 minutes.
Turn the rotary switch to turn on the power. If the battery voltage is insufficient
(approximately ≤3.9V), the display shows the “ ”symbol, and the battery should
be replaced at this time.
The “ ” symbol means that the input voltage or current should not exceed the
indicated value. This is to protect the internal circuit from being damaged.

Warning
The risk of electric shock.
Remove the test leads from the meter before measuring with the current clamp.
Set the rotary switch to the required measurement function and range.
When wiring, connect the common test line first, and then connect the live test line.
When removing the wiring, the live test wire should be removed first.
11. Current Measurement
Set the range switch to the A range position. At this time, it is the AC current measure-
ment state, and select the appropriate range.
Hold the trigger to open the clamp head, and clamp a wire of the tested circuit in the
clamp.
Read the current value on the LCD display.
During measurement, clamping two or more wires of the tested line at the same time
will lead to failure to obtain correct measurement results.
In order to obtain accurate readings, center the wire under test in the clamp as much
as possible.
“ ” means that the maximum input AC current is 600 A.
When measuring current, please press the trigger to open the clamp head, use the
clamp head to clamp the conductor to be measured, and then slowly release the
trigger until the clamp head is completely closed. Please check whether the conductor
is centered in the clamp. If it is not centered in the clamp, additional errors will occur.
The clamp meter can only measure one current conductor at a time. If two or more
current conductors are measured at the same time, the measurement reading would
be wrong.

12. Voltage Measurement
13. Frequency and Duty Cycle Measurement
13.1 Voltage
Insert the black test leads into the COM terminal and the red test leads into the INPUT
terminal, and select the appropriate range.
Turn the rotary switch to the position. At this time, the instrument is in the DC
voltage measurement state. To measure AC voltage, press the “SEL” key to enter
the AC voltage measurement state.
Connect the test leads to both ends of the voltage source or load for measurement.
Read the voltage value on the LCD display.
In the small voltage range, if the test leads are not connected to the circuit under test,
the LCD will have a beat reading, which is normal. This is due to the high sensitivity of
the instrument. When the instrument is connected to the circuit under test, the real
measured value will be obtained.
In the relative measurement mode, the auto range is invalid.
“ ” means that the maximum input voltage is 600V AC or 600V DC.
If the reading measured by the meter is greater than 600V RMS AC, a "Beep" alarm will
sound.

13.2 AC Current
Insert the black test leads into the COM terminal and the red test leads into the INPUT
terminal.
Set the rotary switch to the position, and press the SEL key to enter the AC voltage
measurement state.
Long press “REL/Hz/% ”key to switch to the state of frequency measurement.
Connect the test leads to both ends of the signal source or load for measurement.
Read the voltage value on the LCD display.
Press the “REL/Hz/% ” key again to enter the duty cycle measurement state.
Set the range switch to the A range position. At this time, it is the AC current measure-
ment state, and select the appropriate range.
Hold the trigger to open the clamp head, and clamp a wire of the tested circuit in the
clamp.
Long press the “REL/HZ/%” key to switch to frequency test position.
Read the measurement data on the LCD display.
Press the “REL /Hz/%”key again to enter the duty cycle measurement state.
The measuring range of frequency is 50Hz ~ 100Hz.
The minimum input current is 20A.
“ ”means that the maximum input current is 600A AC (effective value).
The frequency measurement range is 10Hz ~10kHz. If the measured frequency is lower
than 10Hz, the LCD will display “00.0”. The measurement of frequencies below
10kHz is possible, but the accuracy is not guaranteed.
The measuring range of duty cycle is 10 ~ 95%.
“ ” means that the maximum input voltage is 600V AC (RMS).
