Operation guide

Reading hold
During measurement, if it is required to hold reading, touch button, value on display wil l be locked, touch button again, to cancel reading hold.

Back light/Light

During measurement, if environment light is too dark, causing it difficult to read, you could press key for more than 2 seconds, to open backlight or light, which will turn off in about 15 seconds
automatically.
Pressing the button for more than 2 seconds will turn off the backlight
Press the button for 2 seconds, turn on the flashlight, and turn it off automatically after about 15 minutes.

Automatic shutdown

If there’s no operation within 15 minutes after start, instrument will enter standby state, and shut down to save energy.
After automatic shutdown, Press the wake the instrument enter work state.

To measure

Touch the electric source button to start the machine. If the battery voltage is insufficient, the display will display a low voltage symbol, at which point the battery should be replaced. Press the power button again to shut down the machine.
When the instrument is not measured, it will enter the automatic scanning state. The instrument is shown as follows:

NCV (Non -contact voltage detection)
Switch the rotation switch to any gear, hold down the “NCV” key to display EF, and bring the NCV sensor close to the conductor under test, instrument could detect whether the lead being measured is >90V AC voltage. When instrument detects AC voltage, instrument buzzer will alarm and NCV alarm light will flash.

Note:

Even if there’s no alarm indication, voltage may stillexist. Do not depend on non-contact voltage detector to judge whether there’s voltage in the lead. Detection operation may bei mpacted by factors like different socket designs and insulation thickness types etc.

AC/DC current measurement (Do current optional)

Hold the trigger open clamp head and clamp one lead of the cable under test into the clamp head.
When the measured signal is greater than 0.2A, the meter displays the measured current value
Before measuring DC current, press ZEROto set the reading to” 0 “before measuring

DC voltage measurements

Connect the gauge pen to the measured signal. When the measured signal is greater than 0.5V, the meter will display the current DC voltage value.When the measured signal is less than 0.5V, the meter will default to the resistance value and display the internal resistance value of the measured signal.When the measured signal voltage is greater than 42V, the red backliaht will turn on the alarm.

AC voltage measurement
Connect the meter pen to the measured signal. When the measured signal is greater than 0.5V, the meter will display the current AC voltage value and the frequency value of the voltage. When the measured signal is less than 0.5V, the meter will default to the resistance value and display the internal resistance value of the measured signal.When the measured signal voltage is greater than 42V the red backliaht will turn on the alarm.

Resistance, on off measurement
Pen connection resistance measurement, the instrument shows resistance, when measuring the resistance is greater than 60 MQ instrument will show a “—-“. When measuring the resistance is less than 50 0, buzzer alarm lamp, instrument lights flashing.

Single watch pen wire test

Press “SEL” button to switch to LIVE mode, and the meter shows LIVE.
Insert the meter stylus into the power socket. If the instrument detects ac voltage, it will display the voltage signal strength based on the detected signal strength. The instrument induction LCD segment code will display the voltage signal strength. The red backlight is lit up and the buzzer emits an alarm of varying intensity.

Capacitance measure

Press “SEL” key to switch to capacitance
Measure the capacitance with both ends of the test pen and read the measurement from the LCD.
Notice: When measuring large capacitors, it takes time to stabilize the reading When measuring the capacitance with polarity, pay attention to the corresponding polarity to avoid damaging the instrument.

Temperature measurement
Press “SEL” key to switch TEMP, and the red plug of the thermocouple is inserted into the C/F end.The black plug can be inserted into the COM jack. When the reading is stable, the temperature value can be read directly from the display screen.
Notice: The maximum temperature of the randomly packaged K-type thermocouple is 250’C, and the instantaneous measurement can be up to 300°C.

Maintenance

Change battery

Warning: Before opening battery cover of the instrument, remove the pens from the circuit being measured, to avoid electric shock.

If symbol ” appears, it indicates to change the battery.
Unfast en bolts on battery cover of instrument and remove the cover.
Change the old battery.
Place the battery cover.
Note: Do not reverse b attery polarity.

Change pens

Warning When changing the pen, it is required to replace with an identical pen or a pen of the same level. The pen must be in good condition, and level of the pens is: 1000V 10A.
If insulation layer of the pen is damaged, or metal wire of the lead exposes, it is required to change the pen.
