The
following instructions detail
the
correct
procedure
for
battery
charging.
NOTE:
Prolonged
discharge
of
the
battery
can
cause

on
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 13.6 volts.
Overnight
charging
of
the
battery
can
be
accom-
plished by leaving the unit in
"ON"
or
"STANDBY"
and will fully
charge
the newly installed battery.

6.1.2
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-4097 A 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.
I.
Assemble the
connector
kit RPX-4097 A as follows:
pin I to
+
(II
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.
IR
AWG
for up
to
6 feet
20 A
WG
for up
to
16 feet
The
terminals supplied
are
#18-#14
with ins
diameter
.110"-.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
11
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.
