Selecting Measuring Functions and Measuring Ranges
4.1.1 Automatic Range Selection
The multimeter is equipped with auto-ranging for all measuring
functions, except for temperature measurement, and diode and
continuity testing. Auto-ranging is active as soon as the
instrument is switched on. The instrument automatically selects
the measuring range which allows for highest possible resolution
of the applied quantity. When the instrument is switched to
frequency measurement, the previously selected voltage
measuring range remains active.

AUTO-Range Function
The multimeter is switched automatically to the next higher range
at
at
±(3099 d + 1 d → 0310 d), and to the next lower range at
±(
280 d - 1 d
→ 2799 d).
With high resolution the multimeter is switched automatically to
the next higher range at
the next higher range at
±(30999 d + 1 d → 03100 d), and to the
next lower range at ±(
2800 d - 1 d
→ 27999 d).
4.1.2 Manual Measuring Range Selection
Auto-ranging can be deactivated and measuring ranges can be
selected manually in accordance with the following table by
pressing the MAN / AUTO button.
Auto-ranging can be deactivated and measuring ranges can be
selected manually in accordance with the following table by
pressing the MAN / AUTO button.
The desired measuring range can then be selected with the
Y
or
Z
key.
The instrument is automatically returned to range selection when
the MAN / AUTO key is pressed, the rotary switch is activated or the
instrument is switched off and back on again.

Overview: Auto-Ranging and Manual Range Selection
* Via manual measuring range selection only
The multimeter is held in the selected measuring range. If the
range limit is exceeded,
range limit is exceeded,
0L appears at the display. You should
then switch to the next higher measuring range with the help of
the
the
Z
key.
