March 4, 2025

The provided context does not contain specific instructions for fixing a zero Torr issue on the Pfeiffer Vacuum TPG 362. However, you can try the following general troubleshooting steps:

1. Check Sensor Connection – Ensure the gauge sensor is properly connected to the Amphenol C91B appliance connector.
2. Verify Compatible Gauge – Confirm that the connected gauge is compatible (e.g., Pirani TPR 261, TPR 265, TPR 280, TPR 281, or Pirani Capacitance PCR).
3. Inspect Power Supply – Ensure the device is receiving the correct voltage (100–240 VAC, 50–60 Hz).
4. Check for Firmware Updates – If necessary, contact Pfeiffer Vacuum service for a firmware update.
5. Look for Damage or Contamination – Inspect the sensor for contamination or damage and clean or replace it if needed.
6. Ensure Proper Operating Conditions – Verify that the unit is operating within the specified temperature (5–50°C) and humidity limits (≤80% at 31°C).

If the issue persists, contacting Pfeiffer Vacuum support is recommended.
