Advanced Functions

AC current measurement With "Inrush" function
Inrush current is the instantaneous high input current drawn by a power supply or electrical equipment at turn-on. This arises due to the high initial currents required to charge the capacitors and inductors or transformers.

Note: The measuring time of inrush current is about 100ms.
When an electrical device powers is on, inrush current is the surge or momentary burst Of current that flows into it.

Operating Instructions

Insert and replace the batteries

Replace the batteries immediately when the symbol "" appears in the display. Disconnect the meter from power source. Remove the test leads from the measuring device, loosen the screws on the back and remove the lower half of the housing, replace the old batteries and screw the cover back on.

Turn on/off the meter

1. Press and hold the key for about 2 seconds to turn on.
2. When the measurement is finished, press and hold the key for about 2 seconds to switch off the meter.

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

Data hold
Press the button to enable or disable the data hold function.

Automatic shutdown

If there is no operation within 15 minutes after starting up. the meter will automatically shut down to save battery energy.

Cancel Auto Power off
When the meter is power off, please press and hold the button, then turn on the instrument and then release the button. "" symbol will disappear and that means automatic switch-off function have canceled.
Next time you restart the machine, automatic shutdown function will be reactivated again and the display screen shows the "" symbol.

3. Read the measurement results from the display screen. The frequency is displayed when the AC signal is measured.

Note 1:
Minimum identifiable DC current 0.8A.
Minimum identifiable AC current 0.5A.
Minimum identifiable AC/DC voltage 0.8V.
Note 2: Automatic identification priority: resistance, DC voltage, AC voltage, DC current, AC current.
