Battery Information
Go Direct Temperature contains a small lithium-ion battery in the handle. The
system is designed to consume very little power and not put heavy demands on
the battery. Although the battery is warranted for one year, the expected battery
life should be several years. Replacement batteries are available from Vernier
(order code: GDX-BAT-300).
Storage and Maintenance
To store Go Direct Temperature for extended periods of time, put the device in
sleep mode by holding the button down for at least three seconds. The red LED
will stop flashing to show that the unit is in sleep mode. Over several months,
the battery will discharge but will not be damaged. After such storage, charge
the device for a few hours, and the unit will be ready to go.
Exposing the battery to temperatures over 35°C (95°F) will reduce its lifespan. If
possible, store the device in an area that is not exposed to temperature extremes.
Water Resistance
The Go Direct Temperature Probe can be submerged in water for limited periods
of time. It has been tested to a depth of one meter for up to 30 minutes.
However, submerging the sensor impacts the radio operation by absorbing much
of the energy. This may make it difficult or impossible to connect to the sensor
