Switching the Instrument Off Manually
➭
Press and hold the ON|OFF key until OFF appears at the
display.
Shutdown is acknowledged with two, brief acoustic signals.
Switching the Instrument Off Automatically – SLEEP MODE
The instrument is switched off automatically if none of the keys
or the rotary switch are activated for approximately 10 minutes.
Shutdown is acknowledged with a brief acoustic signal.
Transmission mode: In this case, checking is first performed to
determine whether or not the sampling rate has been set to a value
of greater than 10 s. The instrument is switched off after 10
minutes, but the instrument is reactivated 10 s before data is to be
saved to memory. The instrument is then switched back off again.
In the transmission mode, the instrument can be manually
activated with the ON|OFF key. After activation of this type, the
instrument returns to the “SLEEP MODE”.
If the instrument is to be fully shut down, it must first be activated
and then switched off with the ON |OFF key. This ends both
memory mode and transmission mode operation.
We recommend setting the instrument to continuous operation for
transmission mode operation.
The continuous operation mode is not effected by automatic
shutdown.
Disabling Automatic Shutdown
The instrument can be set to continuous operation.
➭
Press and hold the FUNC key and then switch the instrument
on by pressing the ON|OFF key. Continuous operation is
indicated at the display with the
symbol.
Switching LCD Illumination On and Off
➭
Briefly press the ON |OFF key after the instrument has
already been switched on.
Illumination is switched off automatically after approximately 2
minutes.
Note: Electrical discharge and high frequency interference may
cause incorrect displays to appear, and may disable the measuring
sequence. In such cases, switch the instrument off and back on
again in order to reset. If the problem persists, briefly dislodge the
rechargeable batteries or batteries from the connector contacts.
Disconnect the instrument from the measuring circuit before
opening and refer to chapter 14.1, “Rechargeable Batteries and
Batteries”!

Selecting Measuring Functions and Measuring
Ranges
3.1
Automatic Measuring Range Selection
The multimeter is equipped with auto-ranging for all measuring
ranges, except for temperature measurement, and diode and
continuity testing. Auto-ranging is active as soon as the
multimeter is switched on. The instrument automatically selects
the measuring range which allows for highest possible resolution
for the applied quantity. When the instrument is switched to
frequency measurement, the previously selected voltage
measuring range remains active.
The instrument automatically switches to the next highest or next
lowest measuring range for the following measured quantities:
3.2
Manual Measuring Range Selection
Auto-ranging can be deactivated and measuring ranges can be
selected manually in accordance with the following table.
The manual mode is deactivated by pressing and holding the
MAN|AUTO key (approx. 1 s), by activating the rotary switch,
or by switching the instrument off and then back on again.
Automatic range selection is disabled as long as the
MIN/MAX function is active.
