  If your Pfeiffer Vacuum Measuring Instruments display a continuous measuring signal of approximately 0 V, it could be due to several reasons. First, ensure the sensor connection is secure and that the supply voltage is properly established. Next, inspect the measurement cable for any defects or incorrect connections. Finally, the gauge might be in an undefined state; try switching it off, waiting for 5 seconds, and then switching it back on to reset it.

  If your Pfeiffer Vacuum Measuring Instruments show a measuring signal of approximately 0.5 V, it could be due to a Pirani error, indicating a defective measurement system, in which case replace the measurement system. Alternatively, the electronic unit might not be correctly connected to the measurement system; check the connection to resolve this.
