9. GENERAL FUNCTIONS
a) Automatic power-off
• The product turns off automatically if neither key nor the rotary switch is used in a period
of 15 minutes. This feature protects and conserves the batteries and thus lengthens the

Immediately prior to powering off, one long beep sounds.
• When automatic power-off is active, the display shows the symbol < > (B).
• Press any key to turn the product back on after automatic power-off. You may also turn the
rotary switch to OFF before returning it to the desired measuring function.

- Turn off the digital clamp multimeter.
- Press and hold the SELECT key (4) and turn the rotary switch (3) from OFF to any
measuring function. 5 beeps sound and the symbol < > is no longer visible on the LCD.
When automatic power-off is deactivated, 5 beeps sound once every 15 minutes.
