Initial Start-Up – Setup
3 Initial Start-Up
3.1 Inserting Batteries or Rechargeable Batteries
Be certain to refer to chapter 9.2 regarding correct battery
installation.
Momentary battery voltage can be queried in the Info menu (see
chapter 6.3).
Attention!
!
Disconnect the instrument from the measuring circuit before
opening the battery compartment lid in order to replace the
batteries.
Operation with the Power Pack
(accessory for METRAHIT⏐X-
TRA, not included, see chapter 10.3)
Installed batteries are disconnected electronically if the NA X-TRA
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
automatically switched to battery operation without interruption.
3.2 Activation
Switching the Instrument On Manually
Ð 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 illumina-
tion can be activated by briefly pressing the ON / OFF | LIGHT key. Il-
lumination is switched back off by once again pressing the same
key, or automatically after approximately 1 minute.
Switching the Instrument On via PC (METRAHIT⏐X-
TRA⏐OUTDOOR only)
The multimeter is switched on after transmission of a data block
from the PC, assuming the “irStb ” has been set to “ir on ”
(see chapter 6.4).
However, we recommend using the power saving mode: “ir off ”.
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).
