Operation guide

Reading hold

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

Backlight/Light

1. 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 60 seconds automatically.
2. Pressing the button for more than 2 seconds will turn off the  backlight

Automatic shutdown

1. If there’s no operation within 15 minutes after start, instrument will enter standby state, and shut down to save energy.
2. After automatic shutdown, wake the instrument enter work state.
3. Holding SEL/NVC to turn on the power will cancel the automatic shutdown function.
   After shutdown, restart to restore the automatic shutdown function.

To measure

1. 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.
2. 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.

AC/DC current measurement

Connect the measuring pen into the measured signal.
When the measured signal >20mA, the meter will display the current measured current value.
When the measured ac signal >2000mA, the instrument pair displays
the ac current frequency, and the measured current b> 800mA is red backlight warning.

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 backlight 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 backlight 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 M 0 instrument will show a “—-“.When measuring the resistance is less than 50 0, buzzer alarm lamp, instrument lights flashing.

Single watch pen wire test

1. Press “SEL” button to switch to LIVE mode, and the meter shows LIVE.
2. Insert the meter stylus into the power socket.lf 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

1. Press “SEL” key to switch to capacitance
2. Measure the capacitance with both ends of the test pen and read the measurement from the LCD.

Notice:

1. When measuring large capacitors, it takes time to stabilize the reading
2. 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.

1. 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.

1. If symbol ” ” appears, it indicates to change the battery.
2. Unfasten bolts on battery cover of instrument and remove the cover.
3. Change the old battery.
4. Place the battery cover.

Note: Do not reverse battery 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.
