The permissible crest factor CF of the AC quantity to be measured is a function of the
displayed value :
Wave form
of the
measured
quantity

The meter switches automatically to :
the next higher range
at + (3099 1 digit)
the next lower range at + (240/280 digits - 1 digit)
from the 300mA to the 3mA range
at + (24 digits - 1 digit)
provided the 300 mA, 30 mA and 3 A ranges are not selected according
to section 4.1
4.3 Manual range section
You can switch OFF autoranging and select the ranges manually
according to the table on the following page.
Manual mode is switched OFF when pushbutton AUTO/MAN is pressed
(4) for approximately 1s, when the function selector switch (6) is operated,
or when the meter is turned OFF and ON again.
When switching back to autoranging from 30 mV
or 300 mV ranges,
3 V range is automatically selected.

5. Liquid crystal display
5.1Digital 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 upper range limit 3099
( on the range :1999), is exceeded then "OL" is displayed.
With V, A and W measurements, the digital display is updated two times
per second.
5.2 Analog indication
The analog indication with pointer presentation gives the dynamic
response of a moving-coil movement and is updated 20 times per second,
when measuring V, A and W. 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
