■ BATTERY AND EXTERNAL POWER

The instrument is powered by two 1.5V dry batteries (Alkaline C) for

an operating period of typically 250 hours or two 1.2V

rechargeable batteries for an operating period of approximately

125 hours.

Do not use lithium batteries or other batteries with a nominal

voltage greater than 1.8 V. The instrument will be damaged.

When the batteries are low, the low-battery indicator is shown

on the display. At this stage, there is approximately enough

energy for another 30 minutes of use.

For saving of energy the instrument automatically turns off after

10 minutes without operation.

For changing the battery, open the cover of the battery

compartment at the base of the instrument, remove the batteries,

insert new batteries (check polarity) and close the cover again.

Rechargeable batteries must be charged by an external charger.

For operation of the instrument by external power use Agilent

AC adaptor N3979A (9V DC, 1.33 A, ).

Use of the external power supply disconnects the batteries.

Ensure that the mains supply has the correct voltage rating and

safety compliance as relevant. Do not use non-compliant or

doubtful mains equipment.
