The span pot is located to the right of the zero pot (see Figure 3). Use a small flat blade screwdriver to turn the span pot’s adjustment screw and adjust the amplifier’s response output during the calibration procedure. Turn the adjustment screw clockwise to increase the output and counterclockwise to decrease the output. 8 • 65-2330RKSS H S Transmitter... -
Page 9: Junction Box
The amplifier is factory installed in the junction box. A cover on the front of the junction box allows access to the interior of the junction box. A locking set screw on the junction box cover allows you to secure the junction box cover and prevent it from being removed. 65-2330RKSS H S Transmitter • 9... -
