Please carefully read the safety instructions and the user manual before using this product. Use the device only as specified in the user manual. Keep away from children.
The kit includes a digital multimeter, test leads (red and black), a K-type thermocouple, a charger, a carry bag, a user manual, and a warranty.

Charging mode

Whenever the charger is connected, the multimeter enters the charging mode.
The charge symbol is displayed on the screen and an analog bar with the battery charge level in percent appears. It takes about 3 hours to be fully charged. The warning symbol is displayed.
Do not take measurements while charging.

Getting started

Press and hold the Power button (1) for 2 seconds to turn the device on/off. This multimeter has two modes – Smart (Auto) and Professional (Manual). When turned on, it displays Auto (Automatic mode) and enters the Smart (Auto) measurement mode.
In this mode, DC voltage, AC voltage, resistance, and continuity can be measured, and the multimeter can automatically identify the measurement signal.
Press the FUNC button (3) to activate the manual mode. Then, press the SEL button (2) to select the required function.
To return to Smart (Auto) mode, press and hold the FUNC button (3) for 2 seconds.

Data hold

During a measurement, press the H/Flashlight button (4) to turn on the data hold function and display the current reading. Press again to turn the function off and return to the measurement display.

Flashlight

Press and hold the H/Flashlight button (4) for 2 seconds to turn the flashlight on/off.

MAX/MIN mode

Press the MAX/MIN button (5) to switch between the maximum and minimum values. Press and hold (5) for 2 seconds to exit this function.

Fuse Broken indication

When the fuse is blown, FUSE BROKEN is displayed during measurement.
When the fuse is blown, the display shows FUSE when a lead is inserted in the A jack (7) and no further measurements will be taken.

Input jack indicator

When the function set is changed, the corresponding input jack light will flash 5 times to indicate that the test lead should be inserted into the corresponding jack.

Automatic recognition of the current measurement

When the probe is inserted into the A jack, the multimeter automatically switches to the automatic recognition of the current measurement function ( ); switching function sets will not be allowed at this time.
When the multimeter is switched manually to the current function set and no lead is inserted in the A jack, the display shows LEAd (Lead needs to be inserted), and no further measurement is taken.

Auto power turn-off

When you press the Power button (1) to power on, the automatic turn-off function is activated by default and the display shows the symbol. After 15 minutes without any key operation, the multimeter will turn off automatically to save battery energy.
To cancel the automatic turn-off function, press and hold the MAX/MIN button (5) and the Power button (1) simultaneously.
The symbol is not displayed when the automatic turn-off function is canceled.
Do not measure voltage higher than 600V; otherwise, the device may be damaged.
Observe the safety precautions to avoid the risk of electric shock.

Display information

Smart (Auto) measurement mode

The multimeter is turned on in Smart (Auto) measurement mode by default. In this mode, DC voltage, AC voltage, resistance, and continuity can be measured, and the multimeter can automatically identify the measurement signal.
Plug the black test lead into the COM jack (8) and the red test lead into the INPUT jack (9). Connect the probes to the measuring points or in parallel to the circuit to be measured.
The multimeter will automatically recognize the measured signal. If the resistance is <50Ω, an acoustic signal will be emitted continuously. The measurement results will appear on the VA display (6).
