Battery complement:
(Supplied) Two 6 volt, 8 ampere-hour sealed
rechargeable batteries and one nonrechargeable 1.5 volt
mercury cell. Estimated service life of the batteries is 2
years.
Battery charger:
Will recharge battery in 24 hours on HIGH
charging rate and maintain battery charge on LOW charging
rate.
Power transfer:
Chamber temperature shall not change by
more than 0.003C when transferred from line to battery
operation.
Battery endurance:
When fully charged, battery endurance is 2
weeks, at an ambient temperature of 20C and 72 hours at
0C.
115 volts ac 10% 50 to 60 Hz at less than
15 watts or 230 volts ac 10% 50 Hz at less than 15 watts.
Dimensions:
Transvolt - 12 in W x 13 1/2 in D x 9 in H
(40 cm x 34.5 cm x 23 cm).
Transit case - 16 in W x 18 in D x 11 in H
(40 cm x 45.5 cm x 28 cm).
Weight:
Hand carried - approximately 25 lbs (11.4 kg).
In transit case - 36 lbs (16.3 kg).
3.
Installation.
Using the demountable line cord supplied, plug the
instrument into the appropriate power outlet with the BATT CHARGE switch in
the LO position and check that the AC ON lamp on the front panel is
illuminated.
a. The instrument is shipped with the batteries fully charged and
generally will still be maintaining operating temperature on arrival.
However, the standard cells may require 12 to 24 hours to stabilize from any
mechanical disturbance due to common carrier transportation. This recovery
period is considerably reduced if the unit has been hand carried.
The
CHARGE switch should be switched to HIGH for no more than 24 hours to bring
the batteries up to full charge. The switch should then be set in the LO or
trickle charge position.
b. If the unit has been in transit for an extended period of time the
internal batteries may be discharged and the standard cells may not be at
the correct temperature.
The cells should be allowed to stabilize at
operating temperature for at least 10 days before use.
4.
Operation.
The Transvolt Model 9145B (fig 2-13) is operated at all
times from the internal battery.
The AC power energizes the battery-
charging circuit and the instrument should always be left connected to the
ac power with the CHARGE switch in the LO position when not in transit to
maintain the batteries in the fully charged condition.
