Automatic Power Off Infrared Themometer Digital Clamp Multimeter

function exchange

Press Power button, then can measure automatically

Backlight and lighting clamp head

1) if the ambient light is too dark, difficulties to get resulting, press the “ H/ ”key more than 2seconds,Open the back light, automatically shut down in about 30 seconds.

Automatic power off

1) Without operation after 15 minutes ,The meter will enter the sleep state automatically shut down to save power. 1 minutes before the shutdown, each 1 minutes the buzzer 1 sound prompt, dormant into a long sound after that before the shutdown.

Buzzer

Press any key or switch the rotation function , if the function key is effective, the buzzer will be issued "Beep" sound (about 0.25 seconds);set in measuring voltage or current is greater than the alarm value,For example, AC voltage greater than 600V DC voltage is greater than 600V, AC / DC current is more than 200A, the buzzer will continue as pronunciation and to be a over range alarm; Automatically shut down about 1 minutes before the buzzer will sound a warning for the issue of 5 times, before the shutdown will send a warning buzzer sound;；Automatic shutdown function is cancelled, every 15 minutes take 5 warnings.

3.2.1 AC Current

- Max input:400A AC

- Frequency:50Hz

- When ac current is measured, the meter automatically opens an internal low-pass filter to filter out high-frequency current.

3.2.2 DC voltage

- Input impedance:10MW

- Maximum/ input voltage:600V AC (Effective value)OR 600V DC

3.2.4 AC voltage

- Input impedance:10MW

- Maximum/ input voltage:600V AC (Effective value)or 600V DC

In the small voltage range, the meter pen is not connected to the measured circuit, the meter may have jumping reading, this is normal, because of the high sensitivity of the meter, does not affect the actual measurement results

3.2.5 Resistance

- open-circuit voltage:About 0.4V

- Overload protection:600V DC or AC(Effective value)
