HydroSense II Soil Moisture Measurement System

10.1.2 How to replace the battery pack

The process to replace the battery pack is as follows:

Place the HydroSense II face down on a clean dry surface.

Remove the four (4) Philips screws on the back of the HydroSense II

case with the Philips screwdriver provided in the carry case.

Carefully separate the back cover from the front cover, taking care to

keep the HydroSense face down. If the unit is turned face up, the

battery holder inside may fall out. This may lead to damage of the

battery wires.

Unclip the battery connector from the battery holder. This connector

looks similar to the terminals of a 9V PP3 battery.

Do not connect a 9V battery to the battery terminals. This may cause permanent

damage to the HydroSense II. Damage of this kind is not covered under

warranty.

Connect the spare battery holder to the battery connector.

Carefully replace the back cover of the HydroSense II and replace the

four (4) Philips screws.

Turn over the HydroSense II and hold the power button to activate.

10.2 Rod installation/replacement

Threaded inserts in the epoxy body of the CS658 and CS659 allow user

replacement of the stainless steel rods. Initially, these rods are fitted at the

factory and with normal use should provide years of trouble free service,

however sometimes insertion into rocky soils can lead to bending of the probes.

Bent rods should be straightened or replaced as soon as possible since non-

parallel rods can introduce error and can lead to more serious bending or

breaking. Small bends can often be straightened by hand, but more serious bends

may require probe replacement to avoid instrument downtime. Spare rods can be

purchased from your local agent.

The rods have a hexagonal nut-like collar at the base of the unthreaded portion.

When threaded into the sensor body, this collar distributes lateral forces over a

relatively large area to reduce rod bending/deformation during probe insertion

for measurements. The rods must be fully threaded into the sensor body with the

collar in full contact with the probe body. The nut should be tightened using the

open-ended wrench provided with the HydroSense II.
