Making Measurements

Measuring DC or AC Current

Warning: Do not attempt to measure current if the open-circuit vol between the live and ground exceeds 250V, as this may damage the digital clamp meter and pose a risk of electr shock or personal injury.

Caution: - - To avoid damaging the digital clamp meter or the measured dev check the digital clamp meter before measuring current. Ensure

correct input terminals, function settings, and range are used for measurement.

- The current measurement function must be operated between 0°C and 40°C. Avoid suddenly releasing the trigger; the Hall effect is sensitive not only to magnetic fields but also to heat and mechanical stress. Impact can temporarily alter readings.

- For accurate measurement, ensure the conductor is positioned at center of the clamp heads. Positioning outside the center can introduce an additional error of ± 1.0% of the reading.

1. Press to switch DC Current measurement mode, A, will be

displayed in the upper left corner.Then press to switch into AC Current measurement mode, AC will be displayed in the upper left corner.

1. Hold the trigger to open the clamp heads. Place the conductor to be measured in the clamp and then slowly release the trigger until the clamp heads are fully closed. Ensure the conductor is centered in the clamp as shown in the diagram. If not centered, additional errors may occur. The clamp meter can measure only one current conductor at a time; measuring two or more conductors simultaneously will result in incorrect readings.

1. Read the display. Press or to enable and cycle through the manual ranges. If "OL" is displayed, it indicates the input exceeds.

2. In AC current mode, press the key to switch to the second page of the menu, then press the key to enable the surge current measurement mode. At this point, start the electrical device to measure its inrush current. Press the key again to exit this mode.

Note:

• After testing DC current, especially with large currents, the open-circuit baseline might be high. Perform an AC current test to eliminate residual magnetic signals from the clamp heads.
• If there is residual magnetism, press the key to select "Zero." This will temporarily subtract the current residual magnetism from the readings. Note that the residual magnetism value will return after restarting the instrument.

Measuring AC or DC Voltage

Warning: Do not measure any voltage of over 1000 Vdc or 1000 rms to avoid instrument damage or electric shock. Do not apply more than 1000 Vdc or 1000 Vac rms between the common terminal and the earth ground to avoid instru damage or electric shock.

[1] When measuring capacitance, for the 20.00mF range, the measuring duration should be over 30 seconds.
[2] When measuring frequency, the typical waveform is Square or Sine. The signal meets the following conditions:

Frequency	Amplitude (rms)
1 Hz – 20 MHz	≥ 1 V

[3] When measuring duty cycle, the typical waveform is Square.
Note: when measuring resistance and capacitance, the influence of the resistance reactance of the pen itself on the measured value should be considered.

Appendix B: Maintenance and Cleaning

General maintenance

Do not store or place the instrument in a place where the LCD screen will be exposed to direct sunlight for a long time.

Caution: Do not let spray, liquid or solvent touch the instrument or probe to prevent damage to the instrument or probe.

Cleaning:

Check the instrument and probe frequently according to the operation. Clean the external surface of the instrument as follows:

1. Please wipe the floating dust outside the instrument and probe with a soft cloth. When cleaning the LCD, be careful not to scratch the transparent LCD protection screen.
2. Wipe the instrument with a damp but non dripping soft cloth. Please disconnect the power supply. It can be scrubbed with soft detergent or water. Do not use any abrasive chemical cleaning agent to avoid damaging the instrument or probe.

Warning: Please make sure the instrument is dry before re-energizing to avoid electrical short circuit or personal injury caused by moisture.

Charging and Replacement of Battery

During the long-term storage of the device, the battery may be too low due to the self-discharge of the lithium battery and the device cannot be turned on. This is a normal phenomenon.

Please use the attached adapter to pre-charge the device for 0.5 to 1 hour (depending on the storage time) before turning it on. In addition, if the device is not used for a long time, it is recommended to charge it at regular intervals to avoid over-discharge of the lithium battery.

Battery Charging

The lithium battery may not be fully charged when delivered. To make the battery be charged, this device has an approximate charging time of 8 hours and a peak discharge battery life of about 18.5 hours. The power supply and battery indicator symbols in the upper right corner of the screen are explained as follows:

symbol indicates the power-on charging status;

symbol indicates battery power supply;

symbol indicates that there is only about five minutes of use time left.

Please charge as soon as possible according to the relevant tips to avoid damage to the battery.

Charging Method

Connect the digital clamp meter to a computer or other equipment through a USB data cable for charging (pay attention to the load capacity of the power supply equipment to avoid abnormal operation of the equipment).

Note

To avoid overheating of the battery during charging, the ambient temperature must not exceed the allowable value given in the technical specifications.

Replacement of Lithium Battery

Generally, the battery does not need to be replaced. However, when necessary, it can only be replaced by qualified personnel, and only lithium batteries of the same specification can be used.
