4. Operation guide

4.1 Reading hold

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

4.2 Backlight/Light

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

4.3 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, Press the "[SELECT symbol]" button, to wake the instrument enter work state.

4.4 To measure

1. Touch the power button to start the machine. If the battery voltage is insufficient, the display will display a low voltage symbol [battery 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:
   AUTO

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's no alarm indication, voltage may still exist. Do not depend on non-contact voltage detector to judge whether there's voltage in the lead. Detection operation may be impacted by factors like different socket designs and insulation thickness types etc.

4.6 AC/DC current measurement (DC current optional)

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

4.7 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.

4.8 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.
