4.1 Backlit

Switching the Backlit ON and OFF:

The instrument is provided with user selectable Backlit for measurements

in poor light conditions or dark area.

By pressing “AUTO/MAN” and “DATA/MIN/MAX” keys simultaneously the
Backlit can be switched ON.

And by pressing the same keys simultaneously Backlit can be switched

OFF.

Although the main display is activated immediately after the multimeter is

switched on, the two sub-displays must be activated with the MIN/MAX key.
This prevents the contineous display of an undefined condition which was
present at the start of measurement, e.g. open-circuit, as a maxi-mum
value.

The three digital displays, one main display and two sub-displays, show the

measurement value with correct deci-mal point and sign. The selected unit
of measure and the current type are also displayed. A minus sign appears in
front of the number for the measurement of zero-frequency direct quantities,
if the positive pole of the measured quantity is applied to perpendicular

input.

OL” (overload) is displayed, if the actual value falls below the measuring

range lower limit for the following measured quantities: VDC, IDC,
VAC,IAC,mAAC,mADC,capacitance, ,Hz:309999

Refreshing of the digital display occurs at different intervals for the various
measured quantities ..
