Alkaline Battery Operation
For convenient field service, four (4) AA-type alkaline batteries may
be used to power the 525N Series optical test set after the nickel-
metal hydride battery pack has been removed. Alkaline batteries will
provide up to 24 hours of continuous operation.
NOTE: The instrument will not charge alkaline batteries when the
power transformer/NiMH battery charger is connected. This allows
the instrument to be operated using AC power when alkaline batter-
ies are installed.
To use alkaline batteries, do the following:
1. Remove the battery compartment cover.
2. Remove the nickel-metal hydride battery pack.
3. Install four AA-type alkaline batteries as shown inside the bat-
tery compartment. Do not reverse the polarity of the batteries.
4. Replace the battery compartment cover.
AC-Only Operation
The 525N Series optical test set may be used without any batteries
installed. To do so, connect the power tranformer/NiMH battery
charger to the instrument, and plug the other end into an AC power
outlet.
