1. Vacuum Pump Connection Issue

a. Ensure the pump is properly attached to the left interface (no leaks).

b. Verify the hose isn’t kinked or clogged.

2. Incorrect Knob Position

a. Double-check that the knob is turned off (if "off" enables vacuum mode—confirm device manual instructions).

3. Pressure Not Dropping Below 100 psi

a. If the vacuum isn’t pulling enough suction:

i. Check pump functionality (e.g., weak seal, low power).

ii. Test with another gauge to rule out pump failure.

4. Reset Button Not Working

a. Hold the reset button longer (some systems require 3–5 seconds).

b. Try a hard reset (power cycle the entire system).

5. Zeroing Procedure Error

a. After zeroing with the pump attached, wait 10 seconds before removing the pump and clicking zero again.

b. Some systems need ambient pressure re-zeroing after vacuum removal.

6. Mechanical Gauge Failure

a. Tap the gauge gently to free a stuck needle.

b. If hardware is faulty, contact the manufacturer.

Step-by-Step Retry

1. Reconnect the vacuum pump securely.

2. Turn the knob to the correct "off" (vacuum-on) position.

3. Let the pump run until pressure stabilizes below 100 psi.

4. Press/hold reset until the gauge responds.

5. Remove pump, then immediately press zero again.
