Automatic switch-off

The instrument switches off after c. 15 minutes (APO). Continuous actuation of the "APO" but-
ton switches the Auto Power Off function on or off.
Backlighting
Continuous pressing of the "HOLD" button switches on the backlighting.
The illumination switches off automatically after c. 1 minute.
Saving function (HOLD)
At difficult measurement positions, the display cannot perhaps be read correctly.
Pressing the "HOLD" button freezes the current measured value which can then be read in
comfort.
Repeated pressing of the "HOLD" button returns to normal measuring mode.
True RMS
If measuring non-sinus wave forms, low measurement errors can occur if using the True RMS
function, in comparison to using traditional measurement procedures.
Sinus-form and non-sinus form signals can be accurately measured using the True RMS function.
