B. Meter reads 100.0 when the READ switch is depressed.
1. Verify that a sensor is properly connected to the instrument.
2. Ensure the helium level is not actually at the top of the sensor.
C. Other erroneous level indications.
Most inoperative instruments are traced to improper wiring between the sensor and the
instrument. Verify the sensor is connected in accordance with the color code outlined in
the installation section (see table in installation section and Figure 1).
