Initial Start-Up

3.1

Battery test

Four different battery symbols, ranging from fully depleted to fully
charged, continuously indicate the momentary charge level in the
upper left-hand corner of the display
If battery voltage has fallen below the allowable lower
limit, the pictograph shown at the right appears. The
instrument does not function if the batteries have been depleted
excessively, and no display appears.
3.2

Installing or Replacing Batteries

New batteries must be inserted for initial start-up, or if only one
filled segment remains in the battery symbol.

Attention!
Before opening the battery compartment (see page 5 for
location), disconnect the instrument from the measuring
circuit (mains) at all poles.
Eight 1.5 V size AA batteries in accordance with IEC LR 6 are
required for operation of the insulation measuring instrument. Use
new alkaline manganese batteries only.
Rechargeable NiCd or NiMH batteries may also be used. These
can only be recharged externally. We recommend rechargeable
NiMH batteries.
Always replace batteries in complete sets.
Dispose of batteries in an environmentally sound fashion.
Ð Loosen both slotted screws for the battery compartment lid
on the back, and remove the lid.
Ð Remove the battery holder and insert eight 1.5 V size AA bat-
teries with correct polarity in accordance with the symbols.

Attention!
Make sure that all of the batteries are inserted with correct
polarity. If just one battery is inserted with reversed polar-
ity, it will not be recognized by the instrument and may
result in leakage from the batteries.
Ð Push the battery holder into the battery compartment such
that the battery holder's contacts touch the contact springs at
the bottom of the battery compartment (see drawing on
page 3).
If the battery holder is not inserted as specified, the instrument
cannot be supplied with power.
Ð Replace the battery compartment lid and retighten the
screws.
!
Attention!
The instrument may only be placed into service if the
battery compartment lid is securely fastened!
