REPLACING SENSORS
The AL3500 is equipped with Pre-Calibrated Replaceable
Sensor Modules. Although every consumer
breathalyzer requires periodic re-calibration, the AL3500
allows you to simply discard an old or worn sensor and
replace it with a brand new factory calibrated sensor
module.
Sensor Replacement is recommended every 250~300
tests, or at least once a year (whichever is sooner).
Sensor modules can also be replaced if there is defect
or malfunction in the sensor.
Sensor Module Replacement Instructions
Step 1
: Power Off the AL3500 (
VERY IMPORTANT -
The new sensor may be severely damaged if power
is on
).
Step 2
: Remove the old sensor module from the AL3500
circuit board and replace it with a new sensor module.
Step 3
: Make sure the sensor module is seated securely,
and power on the AL3500.
