6.1.I
BATTERY CHARGING
The following instructions detail the correct procedure
for battery
charging.
NOTE: Prolonged
discharge
of
the battery can
cause
permanent
damage to
the
battery. New batteries
must
be
shipped discharged by
law.
1.
Connect
the unit to an AC
power source and
select
"BATTERY"
c)n
the rear panel. Turn the
unit "ON".
The unit will
charge
in either the "BATTERY"
or
"EXT DC"
positions.
2.
Read the
battery voltage by selecting
"BATT"
on the
right LCD. A fully
charged
battery
will
read
I
3
.6
volts.
Overnight charging of the battery can be
accom-
plished by leaving

the
AC power
will
be
used
rather than DC
power.
6.I.2 OPERATION FROM AN EXTERNAL DC
SOURCE
The
following instructions detail
the
correct procedure to
operate the unit
from
an
external DC power
source. The
connector
kit
RPX-4097A
consists
of
a
connector
shell,,
clamp. and
four connector pins.
These parts can
be used
to
fabricate
a
mating plug for
the male
DC
power connec-
tor at
the back of the service monitor and enables
the
user
to
make a
DC power cable to interconnect
a
sepa-
rate power source to the service monitor.
l.
Assemble the connector
kit
RPX-4097A
as
follows:
pin
I to
+ (ll
to
17
VDC)
pin 2 to NC
pin 3 to NC
pin 4 to ground
NOTE: Use wire large
enough
to
carry
6
amps
with
no
significant loss,
ie.
I
tt AWG for
up to 6 feet
20
AWG for up to
16
feet
The terminals supplied are #18-#14 with ins diameter
.
l
10"-. 150"
2.
Select
"EXT DC"
on the rear
panel.
3. with
no
AC
applied to the unit, turn the unit on
and
measure the
External DC voltage
using the
"BATT"
measurement on the
right LCD. This voltage
must be
between
ll
and
17
volts DC
for
proper operation.
NOTE: If AC power
is
connected to the unit,
the
AC power
will
be
used
rather than DC
power.
