Power Management

Both the Display (DH) and Remote (RH) handset use interchangeable rechargeable lithium-
ion battery packs (Li-ion).
• The Display (DH) and Remote (RH) handsets can be run on battery power for
approximately 18 hours. Actual battery power times depends on various factors,
such as operating time versus standby time, use of the display backlight, and
ambient temperature.
• When charge state of battery drops below the required voltage, a warning appears.
Tester automatically shuts down before testing results are affected.
• To save battery power, the Display (DH) and Remote (RH) handset automatically
power down after a certain period of inactivity.
• If the instrument will not be used for a prolonged time it is recommended that the
battery protection strips be inserted to conserve battery charge.
2.3.1

Operating the Display and Remote handset from AC Power

The Display (DH) and Remote (RH) handset can also be operated from an external DC
source (AC/DC adapter). The adapters are universally applicable.
When using the AC/DC adapter to power the handsets, please note that:
• Both handset batteries will receive a trickle charge.
• A power plug will appear in the upper left corner of the Display handset (DH).
CAUTION!
Only the adapter provided with the instrument shall be used. Other types of adapters
may cause damage to the tester.
NOTE:
Do not connect to AC power when testing shielded cables, as this may result in ground
loops which in turn can cause input protection warnings.
