3.3 External Supply Operation

In battery powered operation, the 5184 requires four 9 V alkaline cells (type NEDA
1604, PP3 or equivalent). Each battery fits into its own removable tray accessible
from the rear panel. When they are exhausted, all four batteries should be replaced
together. Care should be taken when exchanging the batteries to observe the correct
polarity which is marked on the inside of the battery trays and the top of the batteries.
The batteries will provide up to eight hours operation at 1 V rms. output level.
Nickel-cadmium rechargeable batteries can be used if preferred, but there will be a
penalty of a reduction in the operating time obtained. In addition it will be necessary to
recharge these batteries in an external charger.
External power can be provided by a stand-alone external power supply (see
Appendix B) providing ±18 V DC, or the Preamplifier Power Output of most
PerkinElmer Instruments lock-in amplifiers which provide ±15 V DC. Connection is
by a DIN 5-way socket on the rear panel of the 5184.
