OPERATING THE AT10.1
25
• If you have an optional temperature compensation probe installed, the
front panel displays LEAD during startup, indicating that the 
temperature compensation is set up for lead-acid batteries. While this is 
being displayed, you can press any front panel key to change the display 
to read NICD, to change the temperature compensation setup for nickel 
cadmium batteries. The choice you make is saved internally, and will be 
used again by the AT10.1 then next time it starts. 
• Turn on the front panel ac circuit breaker. The digital meter displays the
output voltage and current. See Using the Digital Meter on page 24. You 
should hear a soft hum from the AT10.1 as the output current increases. 
NOTE: If you turn on the ac breaker before the dc breaker, 
and you have a filtered model of the AT10.1, there is a 
possibility that the dc breaker will trip when you try to turn it 
on. This is caused by the filter capacitors discharging into the 
battery. To get around this problem, turn off the ac breaker. 
Restart the AT10.1 by turning on the dc breaker first. 
• The green FLOAT indicator lights. Press the
CHRG MODE
key on the
front panel. The FLOAT indicator goes off, and the yellow EQLZ 
indicator lights. Press the 
CHRG MODE
key again to return the charger to
the float mode.
The table below shows the normal factory settings for float and equalize 
voltages, equalize time, current limit setting, and alarm settings. If your 
purchase order specified other float or equalize voltage settings, a tag 
attached to the front panel of the AT10.1 lists the actual voltage settings.
