Preparation for Use
Charging the NiMH Battery Pack
The 525N Series optical test set is shipped with a nickel-metal
hydride (NiMH) battery pack installed. This battery pack must be
charged before the instrument is used for the first time.
To charge the NiMH battery pack, do the following:
1. Plug the power transformer/NiMH battery charger into a wall
outlet.
2. Insert the plug from the power transformer/NiMH battery
charger into the DC input receptacle on the side of the instru-
ment.
3. The red charge state indicator will illuminate. Allow the batter-
ies to charge until the indicator turns off (4 hours maximum).
4. Disconnect the unit from the power transformer/NiMH battery
charger.
The instrument can now be used.
NOTE: The NiMH battery pack and power transformer/NiMH bat-
tery charger will become warm during use. This is normal.
Trickle Charge Function
The 525N Series optical test set incorporates a trickle charge function
that prevents the batteries from being damaged from overcharging.
The instrument can remain connected to the power
transformer/NiMH battery charger indefinitely without damaging the
batteries.
The trickle charge function monitors the condition of the batteries
when the instrument is connected to the power transformer/NiMH
battery charger. If the batteries are drained, the instrument will begin
a maintenance charge cycle to ensure they are at full capacity.
Setting the Internal Clock and Calendar
The 525N Series optical test set incorporates an internal clock and
calendar, permitting the time and date to be recorded when a meas-
urement is saved.
The internal clock and calendar should be set before using the instru-
ment for the first time using the Set 525 Clock feature in the Utilities
mode of the ReportWriter software.
