Installation Practices Do not drop into well – Lower gently to prevent damage to end of sensor.
Installation Practices Do not scrape cable over edge of well – May nick or fray cable.
Installation Practices Do not bend cable sharply – This may close off vent tube*. *Gauge (vented) pressure sensors contain a vent tube inside the cable. If this vent tube is closed off, readings will be wrong.
Installation Practices Install in vertical position – Off vertical may introduce an offset.
Installation Practices Do not lower into mud or silt – This may clog or blind sensor.
Use a strain relief kit to prevent excess pulling on the cable. Installation Practices
Install so that service connector stays dry. Installation Practices
On vented pressure sensors… Install so as to keep desiccant dry. Installation Practices
Replace desiccant when it turns pink. Installation Practices Pink = Bad Blue = Good
Should be done in a clean, dry environment to avoid contamination or moisture damage to the circuitry.
Changing Batteries Top- cap Cable O-rings AA batteries 1.Twisting gently, unscrew the top-cap. Note: Two O-rings provide a water-tight seal and often seal tightly. Pulling hard can cause the O-rings to release suddenly and the top-cap to disengage with enough force to pull the insides out of the sensor.
Changing Batteries 2.Gently separate the top-cap from the body of the sensor. Top-cap remains attached to body via several colored wires. 3.Gently slide batteries out. 4.Insert new batteries – positive terminals towards top-cap. 5.Replace and retighten top-cap.
