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 10
hours (typical) before the batteries must be recharged.
601-3. SPECIFICATIONS
6014. The specifications for the 80S0A-ol are given in
Table 601-1. All other specifications are equivalent to
those given for the 80S0A in Section 1 of this manuaL
601-5. OPERATION
WARNING
DO NOT OPERATE YOUR 80SOA-01 WITH
THE BATTERIES REMOVED.
601-6. Operation of an 8050A-ol 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
1.
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-ol
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
