This section contains information about different features of the HI-4460
Graphical Readout.
Startup
When the HI-4460 is turned on, the screen flickers for one to two seconds. If a
menu key is pressed before this, the menu will exit and the screen will reappear
after the flicker.
Charging
The HI-4460 utilizes a gas gauge microchip to determine battery life. The charger
has a discharge button that works with the gas gauge to discharge the battery to
a reference level and then charge it to the maximum. This enables the HI-4460 to
keep track of the amount of charge that is left.
Battery Operation
Do not disconnect the battery pack from the HI-4460. Disconnecting the battery
will interfere with the calibration of the battery charge status indicator and will
cause a battery fault indication.
If the battery is disconnected, you must recalibrate the battery charge status
indicator.
1. Turn off the HI-4460.
2. With the battery charger connected to the 120/240 VAC mains power
supply, connect the battery charger to the HI-4460.
This will discharge and recharge the battery, and will properly initialize the battery
charge status indicator.
When fully charged, the battery graphical display may indicate a charge level of
97% to 105%. This is normal; this fully-charged level may begin to drop as the
battery ages.
