CF 26 5 4/2001

Transducer Excitation

The bridge excitation supply voltage is set by SWB-1 and potentiometer E. Set SWB-1 ON for a fixed 10 Volts. This

will provide the best temperature stability. The supply can be adjusted between 5 and 10 Volts by setting SWB-1

OFF and adjusting potentiometer E. The supply will deliver up to 120mA current at any voltage setting to power up

to four 350-ohm sensors.
