<Preparation of Sensor Unit>
1
Remove the sensor cover of the
sensor unit.
Push the tabs on the both sides with
your fingers to move up the sensor
cover.
Remove the sensor cover to check
the sensor.
2
Insert the sensor pin to the
socket on the board.
Because the sensor has two pins,
align them with the open holes on the
board when inserting or removing.
3
Put the sensor cover back on.
CAUTION
When installing the sensor, push it while aligning its pins with the socket on the board. Ignoring
this may bend and damage the sensor pins.
After the sensor is installed, always perform a calibration (zero adjustment and span adjustment).
Do not disassemble the sensor because it contains electrolyte. If contact occurs, rinse the area
immediately with a large quantity of water.
The sensor must be stored under normal temperature/humidity in a clean place away from direct
sunlight.
