4.1 Backlit
The instrument is provided with user selectable Backlit for
measurements
in poor light conditions or dark area.
Switching the Backlit ON and OFF:
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 t
hree digital displays, one main display and two sub-displays, show the
measurement value with correct decimal 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 above the measuring
range upper limit for the following measured quantities: VDC, IDC,
VAC,IAC,mAAC,mADC,F ‘
Ω
’
,Hz:.
Refreshing of the digital display occurs at different intervals for the various
measured quantities ..
