Turn the Control Knob to select one of the nine possible films, then press the Control Knob to enter the film parameters menu.

Turn the Control Knob to set the first film parameter (density). The parameter value is shown in Display 2 . Press the Control Knob to save the value and move to the next film parameter. If you press Clear , the film parameter returns to its original value. Continue to set each parameter. When the last film parameter is entered, the SQM-160 returns to normal mode. See Chapter 2 for detailed instructions on setting Film Parameters.

To Enter the system menu, press Program, then Prev. Set system parameters by turning, then pushing, the Control Knob as described above. See Chapter 2 for detailed instructions on setting System Parameters.

If the sensor(s) you selected during film setup are connected to the SQM-160, the Crystal Status LEDs should be lit. If not, return to the Film Parameters menu and set the Sensor Average parameter to the desired sensor(s).

If the Crystal Status LED is flashing, it is most likely that sensor is not properly connected. Sigma supplies a small test crystal with each oscillator module that can be used to test sensor connections external to the vacuum chamber. Referring to Section 1.4, disconnect the oscillator from its 6” BNC cable. Attach the test crystal to the oscillator’s feedthrough connector. The Crystal Status LED will remain lit if the external sensor connections are correct.

Refer to the Sensor Selection, Frequency Display and Sensor Min/Max sections of Chapter 2 for information that can assist in troubleshooting sensor problems.
