What to do if Raven Laboratory Equipment displays DI high vacuum error?
- CcodymaddoxSep 5, 2025
If the Raven Laboratory Equipment is showing a DI high vacuum error, follow these steps: 1. Disconnect the vacuum switch from the product cable and test for continuity between pins A and C. If the OHM meter reads a short, the switch is good. If it reads open, the vacuum switch is bad. 2. Check for obstructions from the inlet of the tank. Look for debris in the inlet, a plugged filter/strainer, a hand valve turned in the wrong direction, or an obstruction in the outlet of the chemical tank.
