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.
