APPA A1 Mini AC/DC Clamp Meter

Safety Information

Use the Meter only as specified in this manual or the protection by the Meter might be impaired.

Always use proper terminals, switch position and range for measurements.
Verify the Meter’s operation by measuring a known voltage. If in doubt, have the Meter serviced.
Do not apply more than the rated voltage, as marked on Meter.
To avoid false readings that can lead to electric shock and injury, replace battery as soon as low battery indicator blinks.
Do not use Meter around explosive gas or vapor.
To reduce the risk of fire or electric shock do not expose this product to rain or moisture.
Individual protective equipment should be used if HAZARDOUS LIVE parts in the installation where measurement is to be carried out could be ACCESSIBLE.

Caution

Do not expose Meter to extremes in temperature of high humidity.

ACA & DCA

Auto ACA&DCA Detection / ACA & DCA

Dut to the high sensitivity of the clamp meter, perform DCA Zero in the same direction as measurement to avoid interference by external magnetic field.

Data Hold

The display will flash continuously if the measured signal is larger 50counts than the display reading. However, it cannot detect across the AC and DC Current.

DCA ZERO

Inrush Current

The meter calculates the RMS value for 100ms as detecting a more than 5A current.

Low Pass Filter

The cut-off frequency of the low pass filter is about 160Hz with attenuation characteristic of approx-24db/octave.

Backlight on/of

Voltsense

The number of dashes displaying on the LCD indicates the electric field intensity.
If no indication, voltage could still be present.
