Safety Operation Specifications

warning

In order to avoid possible electric shock or personal injury and other safety accidents, please abide by the following specifications:

• Please read this manual carefully before using the instrument, and pay special attention to safety warning information.
• Strictly observe the operation of this manual and use this instrument. Otherwise, the protection function of the instrument may be damaged or weakened.
•  Please be careful if the measurement exceeds 30V AC true RMS, 42V AC peak or 60V DC. There may be danger of electric shock at this kind of voltage
• By measuring the known voltage to check whether the meter work is normal, if it is not normal or damaged, do not use it again.
• Before using the instrument, please check whether there is any crack or plastic damage in the instrument case. If you do, do not use it again.
• Before using the instrument, please check whether the probe is cracked or damaged. If so, please replace the same type and the same electrical specifications.
• The instrument shall be used in accordance with the specified measurement category, voltage or current rating.
•  Please comply with local and national safety code. Wear personal protection equipment (such as approved rubber gloves, masks and flame retardant clothes, etc.) to prevent being damaged by electric shock and electric arc due to exposed hazardous live conductor
• When it shows low battery indicator, please replace the battery in time in case of any measurement error.
• Do not use the instrument around explosive gas, steam or in wet environment.
• When using the probe, please put your fingers behind the finger protector of the probe.
• When measuring, please connect the zero line or the ground line firstly, then connect the live wire; but when disconnecting, please disconnect the live wire firstly, then disconnect the zero line and ground line.
• Before opening the outer cabinet or battery cover, please remove the probe on the instrument. Do not use the instrument in the circumstances that the instrument is taken apart or battery cover is opened.
• It only meets the safety standards when the instrument is used together with the supplied probe. If the probe is damaged and needs to replace, the probe with same model number and same electrical specifications must be used for replacement.

Measurement operation

Smart (AUTO) measurement:

This measurement mode is default when power on. In this mode, DC voltage, AC voltage, resistance, continuity can be measured, and the meter can automatically identify the measurement signal.

1. Press keyto power on, display Auto and enter the intelligent measurement mode.
2. Insert the red probe into “The INPUr jack and the black probe into the “ COM ” jack.
3. Contact the probe of the probe with both ends of the measured power supply or resistance (parallel), and the meter will automatically recognize the measured signal.
4. Read the results from the display.

NOTE, The minimum measurable voltage is 0.8V

Non-contact AC voltage detection

1. Press key to power on, display Auto and enter the intelligent measurement mode.
2.  Press and hold “|” key to select “NCV ” gear.
3. The NCV induction area is gradually close to the conductor.
4. When the weak electric field signal is detected, it will display “L”; the backlight on, the buzzer will sound slowly and the green light on.
5. When the strong electric field signal is detected, it will display “–H”; the backlight on, the buzzer will sound quickly and the red light on.

• Data hold
  • Press key to turn on or off data holding.
• Backlight
  • Press key to turn on or off the backlight.
• Flashlight
  • Press and hold key for about 2 seconds to turn on or off the flashlight.

Auto power off:

• If there is no operation within 15 minutes, the meter will auto power off.
• Press and hold the one key then turn on the power to cancel the auto power off function and the symbol will no longer be displayed. The next time the key is turned on, the automatic shutdown function will be restored.

WARNING

• It is not possible to measure voltages higher than 600V, otherwise the instrument may be damaged.
• Pay special attention to safety when measuring high voltage to avoid electric shock or personal injury.
• Before use, test the known voltage with the meter and make sure the meter is in good function.
