CAUTION
SHARP PINS
Care and Safety
The rods of the SM150 are sharp in
order to ease insertion. Care must be
taken and handling precautions
followed.
Avoid touching the rods or exposing
them to other sources of static charge,
particularly when powered up.
Keep the SM150 in its protective tube when not in use.
Take care when attaching cables to ensure that the connectors are clean,
undamaged and properly aligned
before
pushing the parts together.
Do not pull the SM150 out of the soil by its cable.
If you feel strong resistance when inserting the SM150 into soil, it is likely you
have encountered a stone. Stop pushing and re-insert at a new location.
Do not touch the pins, particularly when the sensor is
attached to a cable. An electrostatic discharge from
your body can typically cause a temporary -10mV
offset in sensor readings for up to one hour. At worse
it may permanently damage the sensor.
