Bench Check Procedure
1. Sensor Input:
In order to provide an input to your STA TPRG you will need to use an appropriate input
simulator. By example – if you plan to use your STA with a thermocouple input you will
need to use a thermocouple simulator to provide the appropriate input during your bench
check. The same goes for an RTD simulator, a millivolt source, a potentiometer, or a
decade resistance box. Use whichever input source is correct for your intended application.
Please see Figure 2.1 for the correct sensor input connections.
2. Power Input:
Connect the appropriate power source as shown in Figure 2.2.
