Calibrating the Sensor
Calibration is not always necessary, especially if you are
measuring a change in temperature rather than absolute
temperature values. However, it is possible to calibrate
the sensor. For detailed information, see Appendix B
.
Battery Usage
The Wireless Temperature Sensor includes a 3 V coin
cell battery (CR2032). Battery life is very important to
making the sensor simple and always ready to use, so
all of the PASCO wireless products are designed for
long battery life. For example, the sensor turns itself off
after a short time of inactivity.
We expect more than one year of battery life, but the
actual amount depends on factors such as the data
collection sampling rate.
Sensor Storage
If the sensor will be stored for many months, we
recommend that you remove the battery to avoid
damaging the sensor in case of a battery leak.
Battery Removal and Replacement
If the sensor’s battery status LED blinks red, the battery
may need to be replaced. Replacing the small,
disk-shaped battery involves removing the Battery
Compartment Door on the bottom of the sensor,
removing the old battery, installing a new battery of the
same type, and replacing the Battery Compartment
Door. The procedure needs a coin and a CR2032 three
volt battery.
(NOTE: This battery is commonly available in electronic
and commercial stores.)
Remove the Battery Compartment Door
Hold the sensor bottom-side
up. Use a coin in the slot to
turn the Battery Compartment
Door counterclockwise
(left-to-right) until the indicator
on the door is aligned with the
second mark on the sensor.
Turn the sensor bottom-side
down so that the Battery
Compartment Door can drop
into the palm of your hand.
Make sure that the battery door gasket stays on the
door. The gasket is an “O-ring” that is held in place by
the tabs on the door. Please do not touch the inside of
the battery compartment
Remove the used battery from the Battery Compartment
Door and replace it with a new identical type battery.
Note that the battery is held in place by the small tabs on
the door
. The side of the battery with the “+” on it should
be against the door.
Replace the Battery Compartment
Door
Put the Battery Compartment Door
with the new battery back onto the
sensor. Align the indicator on the
door with the second mark, and
use the coin in the slot to turn the
door clockwise (right-to-left) until
the indicator is aligned with the first
mark on the sensor.
(See “Battery Disposal Instructions” under Technical
Support.)
