Safety Information

Warning: Read this manual before using the instrument. The "Warning" mark indicates conditions and operations which may cause danger to users. The "Caution" mark refers to conditions and operations which may cause damage to the instrument or equipment.

General Safety Warnings:

• 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.
• Voltage applied between terminals or between each terminal and grounding point shall not exceed the rated value.
• By measuring the known voltage to check whether the meter works normally, if it is not normal or damaged, do not use it again.
• Before using the instrument, please check whether there are cracks in the instrument shell or plastic parts damaged. If so, please do not use 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.
• Do not exceed the lowest rated Category of Measurement (CAT) rating in products, probes or accessories.
• Do not measure the current when the probe is inserted into the input jack.
• Don't work alone.
• 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 neutral wire or the ground wire firstly, then connect the live wire. When disconnecting, please disconnect the live wire firstly, then disconnect the neutral wire and ground wire.
• Before opening the outer cabinet or battery cover, please remove the probe on the instrument. Do not use the instrument in 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 be replaced, use a probe with the same model number and electrical specifications.

Operating Instructions

Video Demonstration

Watch this video for a visual guide on how to use your GVDA Clamp Meter for various measurements:

Video demonstrating various functions of the GVDA Clamp Meter.

1. Smart Measurement Mode

The meter enters smart mode by default upon powering on. In this mode, it can automatically identify and measure AC/DC voltage, AC/DC current, resistance, and continuity. Current is measured with the clamp, while other measurements use the test leads.

• Press the power button to turn on the meter. After self-test, the meter will display “Auto”.
• No need to select a specific measurement function; simply measure the AC/DC voltage, AC/DC current, resistance, or continuity. The instrument will automatically identify and measure.
• Read the measurement results from the display screen. The frequency is displayed when AC signals are measured.

2. AC/DC Current Measurement (Professional Mode)

• Press the power button to turn on the meter. After self-test, the meter will display “Auto”.
• Press the FUNC button to set the pointer to “A”, then press the FUNC button again to select AC or DC current measurement function.
• In DC current measurement, if the display is not zero when not measuring, press and hold the ZERO key to clear it.
• Open the clamp by pressing the trigger, clamp the conductor to be tested, and slowly release the trigger until the clamp is completely closed. Ensure the conductor is centered in the pliers for accurate readings.
• Read the measurement results from the display screen. Frequency is also shown when measuring AC current.

3. Inrush Current Measurement

• Press the power button to turn on the meter. After self-test, the meter will display “Auto”.
• Press the FUNC button to set the pointer to “A”, then press the SEL button to select inrush current measurement function, displaying “INRUSH”.
• Open the clamp by pressing the trigger, clamp the conductor to be tested, and slowly release the trigger until the clamp is completely closed.
• Turn on the device to be tested (e.g., a motor) and then trigger the measurement by the surge current.
• Read the measurement results from the display screen. The measuring range of inrush current is 5-600A.

4. AC/DC Voltage Measurement

• Press the power button to turn on the meter. After self-test, the meter will display “Auto”.
• Press the FUNC button to set the pointer to “V”, then press the FUNC button again to select AC or DC voltage measurement function.
• Insert the red probe in “INPUT” jack, insert the black probe in “COM” jack.
• Contact the probes to the measured circuit (connect to the measured power supply or circuit in parallel).

5. Temperature Measurement

The GVDA Clamp Meter can measure temperature using the included K-type temperature probe.

• Connect the K-type temperature probe to the meter's input jacks.
• Select the temperature measurement function (usually indicated by °C or °F).
• Place the probe tip on the object or area whose temperature you wish to measure.
• Read the temperature from the display.

6. NCV Measurement (Non-Contact Voltage)

The NCV function allows you to detect AC voltage without direct contact with the conductor, enhancing safety.

• Select the NCV function on the meter.
• Bring the NCV sensor (usually at the top of the clamp jaw) close to the conductor.
• The meter will indicate the presence of AC voltage through an audible alarm and/or visual indicator.

7. Data Hold

Press the HOLD button to freeze the current reading on the display. Press again to release.

8. Flashlight

Press and hold the HOLD button for more than 2 seconds to turn the flashlight on or off.

9. Auto Power Off

If there is no operation within 15 minutes after starting up, the meter will automatically shut down to save battery energy. To cancel this feature, press and hold the FUNC key, then press the power button to turn on the instrument. The display will show a “no-auto-off” symbol. Restart the machine to restore the automatic shutdown function.
