(1 % of rdg. + 10 Digits)
1) With zero adjustment
2) With temperature : Error data apply per 10 K change in temperature.
With frequency : Error data apply to a display of 10% of the measuring
range.
3) With unknown waveform (crest factor CF>2), measure with manual
range selection.
4) With the exception of sinusoidal waveform.
5) After the “
^
” symbol is displayed.

4.1
Digital display
The digital display (9) shows the measured value with correct location of decimal
point and sign. The selected measuring unit (12) and the function (11) are
simultaneously displayed. When measuring DC quantities, a minus sign appears
in front of the digits, when the positive pole of the measured quantity is applied to
the “
^
” input terminal. When exceeding the upper range limit 30999 [on the
range F:3099], “OL” is displayed.
With V, A and
W
measurements, the digital display is updated two times per
second.

Meter reaction
4.2 Analog indication
The analog indicator with pointer presentation gives the dynamic response of a
moving coil movement and is updated 20 times per second. Analog indication
is of particular advantage when observing variations of measured values and
for calibration procedures.
The analog indicator has its own polarity indication.
When measuring DC quantities. the analog scale (15) has a negative range of
5 scale divisions. so that variations of the measured values around “zero” can
be observed exactly. When the measured value exceeds the range of
indication, the left triangle (16) is shown before the polarity of the analog
indicator switches over after approximately 0.7s. Exceeding of the measuring
range (>30999 digits, on the range F:>3099) is shown by the right triangle(13).
The graduation of the analogue scale is automatic which is helpful for the
manual range selection.
4.3 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/MAX” keys simultaneously the Backlit can be switched
ON.
And by pressing the same keys simultaneously Backlit can be switched
OFF.

“DATA” hold / compare facility
The DATA (hold) function allows you to automatically “hold” measured values
This is particularly useful, for instance, when applying the probes to the
measuring point requires full attention. When the measured value is applied
and the “condition” according to the table shown below is met, the meter holds
the measured value on the digital display and issues a sound signal. The
probes can now be removed from the measuring point and the measured
value on the digital display (9) can be read. When the measured value falls
below the limit specified in the table, the meter is reactivated for a new storage.
If the new stored value differs by less than 100 digits from the previous value
the sound signal is issued twice (DATA-Compare)
