Instruction manual

HS2 and HS2P

The HydroSense II is an easy-to-use, portable device for measuring volumetric

water content of soil. The major components of the system are the display, the

sensor, and the software. A sensor with 12 cm rods (model CS659 or CS659P)

and a sensor with 20 cm rods (model CS658 or CS658P) are available.

Campbell Scientific offers the HS2, the standard HydroSense II system, and

the HS2P, a HydroSense II system with a strong handle and pole. FIGURE

1-1, HS2 HydroSense II System (p. 1) shows the HS2 and FIGURE 1-2, HS2P

HydroSense II Pole System (p. 1) shows the HS2P.

Throughout the manual, HydroSense II refers to both the HS2 and

HS2P, unless specified otherwise.

2. Cautionary Statements

• The connectors that connect the HydroSense II display to the sensor are a

push-pull type with locators to align the connectors. DO NOT TWIST.

The connectors can be damaged if the user twists them or attempts to

screw or unscrew them.

• Remove the AA batteries before putting the HydroSense II display into

storage.

• An unobstructed view of the sky may be required to achieve the most

accurate global position data possible from the HydroSense II GPS.

• Sensor rods must be completely inserted into the soil before making a

measurement.

3. Quickstart

1. Remove the HS2 display or HS2P from the carry case.

2. Remove the blue protective strip from the display window.

Steps 3 and 4 are for the HS2 only because the HS2P comes fully

assembled. If using an HS2P, go directly to step 5.

3. Remove the HS2 sensor from the carry case.

4. Connect the HS2 sensor to the display by mating the connector on the

cable to the connector at the bottom of the display. DO NOT TWIST the

connectors.

The connector is a push-pull type with locators to align the

connectors. The connectors can be damaged if the user

attempts to screw or unscrew them. To mate the

connectors, simply bring them together and turn until they

are aligned, then applying firm pressure, slide them together

until they click. To disconnect, pull back on the connector

collar with the thumb and forefinger and pull the two

connectors apart.
