601-1. INTRODUCTION
601-2. The Option 8050A-Ol replaces the standard
8050A power supply with a power supply
that
will operate
from either rechargeable batteries
or
line power.
If
the
batteries are fully charged, your 8050A will operate for l
O
hours (typical) before the batteries must be recharged.
601-3. SPECIFICATIONS
601-4. The specifications for the 8050A-Ol are given in
Table 601-1. All other specifications are equivalent
to
those given for the 8050A in Section l
of
this manual.
601-5. OPERATION
WARNING
DO
NOT
OPERATE YOUR 8050A-01 WITH
THE BATTERIES REMOVED.
601-6. Operation
of
an
8050A-O
l differs in two respects
from operation
of
a standard 8050A - battery charging
and the BT annunciator
on
the display. When the BT
annunciator appears,
on
the display during operation,
measurement accuracy may deteriorate beyond the limits
specified in Section l.
If
the BT annunciator appears
and
you still need
to
make additional measurements before
recharging, set the
POWER
switch
to
the
OFF
position
for a couple
of
minutes, then set the
POWER
switch back
to the
0 N position.
If
the BT annunciator does
not
appear
immediately, you have
at
least two minutes
of
in-
specification operation.
If
the BT annunciator appears
immediately after the
POWER
switch
is
set back to the
ON position, none
of
the measurements should be
accepted as being within the specified
limits._
Normally,
when the BT annunciator appears, recharge the batteries
as soon as possible.
601-7.
To
recharge the batteries, connect the
8050A-O
l
to line power and set the
POWER
switch
to
the
OFF
position.
If
the
POWER
switch is set
to
the ON position,
the batteries receive a reduced charge that
is
sufficient
to
maintain their charge level
but
insufficient
to
charge the
batteries
to
a higher level.
