CHARGING PROCEDURE
Step 1. Plug the charger into a suitable AC source.
Step 2. Set the probe switch to OFF. Insert the plug on the
charger cable into the probe's CHARGER jack.
Step
3. The battery is now charging. This may take
approximately one hour, depending on how deeply the batteries
are discharged. When charging is complete, the charger
automatically goes into a trickle charge and will continue to do so
until the probe is disconnected.
BATTERY TIPS
NiCd batteries have several characteristics that can affect both
their performance and operating life. The following tips advise
you how to take advantage of these characteristics to get the
most out of your probe’s battery.
• Although NiCd batteries are rated for operation in
temperatures from -20°C to +65°C (-4 °F to +140 °F),
operating the probe in extreme temperatures will reduce
operating time significantly. The optimum operating
temperature range for these batteries is
+20°C to +30°C (+68°F to +86°F).
• The battery in the HI-4450/FP2080/FP4080/FP5080
probe does not require periodic "deep discharges" to
reverse the capacity-depleting "memory effect" caused
by repeated shallow discharges; however,
undercharging can reduce battery capacity. Therefore,
after the charging procedure is complete, be sure that
the battery is fully charged before resuming field
operation.
• If the battery exhibits low terminal voltage during
charging, or if it appears unable to acquire or maintain
an appreciable charge, individual cells in the battery may
be shorted or damaged. If, for any reason, your battery
needs replacement, contact ETS-Lindgren Customer
Service for assistance.
