Operation guide

4.1 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.
4.2 Torch

1. Long press the flashlight button for 2 seconds, turn on the flashlight, and turn it off after about 1 minute.

4.3 Auto Power -Off

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, Press the ” ” button, to wake the instrument enter work state.

4.4To 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:

4.5 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:

1. Even if there is no alarm indication, the voltage may still be present. Do not rely on the non-contact voltage to determine whether a wire has a voltage. Probe operation may be influenced by socket design, type of insulation thickness, etc. In NCV detection mode, the meter does not measure voltage, resistance, and current simultaneously.

4.6 electric current measurement
4.6.1 Ac current and AC current frequency measurement

1. Press the clamp, open the clamp mouth and clamp one of the wires under test.
2. When the measured signal is greater than 0.2a, the meter display displays the current value and frequency value of the measured conductor. (Note: The meter can display the frequency value only when the current value is greater than 35A)

4.6.2 Dc current measurement (Test instrument with dc current function)

1. Press the clamp, open the clamp mouth and clamp one of the wires under test.
2. When the measured signal is greater than 0.2a, the meter display displays the current value and frequency value of the measured conductor.

4.7 DC voltage measurements
4.7.1 DC voltage measurements (V)
Connect the test pen to the signal being tested. When the measured DC signal is greater than 0.5V, the display voltage value. When the measured DC signal is <0.5V, the instrument uses the default resistance value and displays the resistance value of the measured signal.
4.7.2 Dc voltage measurement(mV).

1. Press SEL button to dc voltage mV, the instrument shows mV
2. Connect the test pen to the test signal. When the test signal is <600mV, the instrument will display the current dc voltage value under test; when the test signal is >600mV, the instrument will display “OL”.

4.8 AC voltage measurement
4.8.1AC voltage measurement (V)
Connect the test pen to the signal being tested. When the measured AC signal is greater than 0.5V, the display displays the voltage and frequency values. When the measured AC signal <0.5V, the instrument default resistance value, display the measured signal internal resistance value.

4.8.2 Ac voltage measurement(mV)

1. Press SEL to enable the mV function. Instrument display mV
2. Connect the meter and meter pen to the signal under test. When the measured signal is less than 600mV, the meter displays the measured current, dc voltage value. When the measurement signal is > 600mV, the instrument displays “OL”.

4.9 resistance measurement

1. Connect the test pen to the resistance to be measured. The main display of the instrument will display the measure( resistance value. When the measurement resistance is less than 50 ci , the instrument buzzer sound alarm, indicator light on.

4.10 Single watch pen wire test

1. Press 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.

4. 11 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.
4.12 Temperature measurement
Press 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:
1. The maximum temperature of the randomly packaged K-type thermocouple is 250°C, and the instantaneous measurement can be up to 300°C.

Maintenance

5.1 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.

5.2 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 levelof 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.
