power pack is used, and need not be removed from the instrument.
If rechargeable batteries are used, they must be recharged externally.
If the external power supply is switched off, the device is automati-
cally switched to battery operation without interruption.
3.2 Activation
Switching the Instrument On Manually
∞
Press the ON / OFF | LIGHT key until the display appears.
Power-up is acknowledged with a brief acoustic signal. As long as
the key is held depressed, all of the segments at the liquid crystal
display (LCD) are illuminated.
The LCD is depicted on page 13.
The instrument is ready for use as soon as the key is released.
Display Illumination
After the instrument has been switched on, background illumination
can be activated by briefly pressing the
ON / OFF | LIGHT key. Illu-
mination is switched back off by once again pressing the same key, or
automatically after approximately 1 minute.
Switching the Instrument On via PC
The multimeter is switched on after transmission of a data block from
the PC, assuming the “i rStb” has been set to “i r on” (see chapter 6.4).
However, we recommend using the power saving mode: “i roff ”.
Note!
Electrical discharge and high frequency interference may cause
incorrect displays to appear, and may disable the measuring
sequence.
Disconnect the device from the measuring circuit. Switch the
instrument off and back on again in order to reset. If the problem
persists, briefly dislodge the battery from the connector contacts
(see also chapter 9.2).
