* Prone to flooding!!Keep desiccant dry or use absolute sensors.
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.

Changing Batteries
Changing Batteries
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.

Calibration
Overview
Calibration Overview
Aqua4Plus’ built in calibration calculator allows you to easily perform two-point calibrations on each channel.
Calibration Overview
Using the interactive calculator, enter known points and take measurements.
Aqua4Plus determines the needed calibration values.
Calibration Overview
Step-by-step instructions display on the calibration window for ease of reference.
