Do not take measurements while charging.

Getting started

ATTENTION! This device must only be operated by a qualified specialist.
(A qualified specialist is a person whose competence is officially confirmed by relevant documents, who has the necessary knowledge and experience to work safely with this device and is authorized to work with circuits with the appropriate voltage class.)

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.

Range selection
Press the RANGE button (13) to enter the manual range selection mode, and then press again to switch the range. Only voltage, resistance, and current (in mA) measurements are available in this mode. Press and hold the RANGE button (13) for 2 seconds to return to the automatic range selection mode.

This function can’t be used in the Smart measurement mode.

Function selection
Press the FUNC button (15) to activate the manual mode. Then press the SEL/Flashlight button (6) to select the required function.
To return to Smart (Auto) mode, press and hold the FUNC button (15) for 2 seconds.

Data hold
During a measurement, press the HOLD/REL button (14) to turn on data hold function and display the current reading. Press again to turn the function off and return to measurement display.

This function can’t be used in NCV/Live mode.

Flashlight
Press and hold the SEL/Flashlight button (6) for 2 seconds to turn the flashlight on/off.

MAX/MIN mode
Press the MAX/MIN button (16) to switch between maximum and minimum values. Press and hold the FUNC button (15) for 2 seconds to exit this function.

• This function can’t be used in capacitance, frequency/duty cycle, temperature, NCV/Live modes.
• During measurement of maximum/minimum values, the multimeter will automatically enter the manual range mode.

Relative value measurement
Press the HOLD/REL button (14) for at least 2 seconds to turn relative value measurement on or off.

This function can’t be used in capacitance, frequency/duty cycle, temperature, NCV/Live modes.
During measurement of relative values, the multimeter will automatically enter the manual range mode.

Relative value measurement
Press the HOLD/REL button (14) for at least 2 seconds to turn relative value measurement on or off.

• This function can’t be used in capacitance, frequency/duty cycle, temperature, NCV/Live modes.
• During measurement of relative values, the multimeter will automatically enter the manual range mode.

Fuse Broken indication
When the fuse is blown, the symbol tis displayed.
When the current measurement function is selected, the symbol FUSt will be displayed at the same time and no further measurements will be taken. Please replace the fuse in time.

Input jack indicator
When the function 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 current measurement
When the test lead is inserted into the A jack, the multimeter automatically switches to the automatic recognition of current measurement function ( ); switching functions will not be allowed at this time.
When the multimeter is switched manually to the current measurement function 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 ( ) 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 SEL/Flashlight button ( ). The symbol is not displayed when the automatic turn-off function is cancelled.

Display information

Smart (Auto) measurement

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.
