Section 3. Calibration and
Performance
3.1. Heater Adjustments
The sensor heater circuit can be adjusted
to control the sensitivity of the unit. A
heat setting that is too high causes
instability due to excessive sensitivity and
shortens sensor life. A heat setting that is
too low causes decreased sensitivity. The
heater adjustment LEDs,
heater
adjustment, and calibration reference
bottle is a unique system for setting the
correct sensor heat (sensitivity) for
optimum performance and long sensor
life. To check the heater setting:
1.
Slide the mode switch to AUTO, slide
the leak switch to SMALL, turn ON
the unit and allow it to stabilize
(approximately 2 minutes).
2.
When stabilized (at approximately 1
click per second), briefly touch the
probe tip to the calibration reference
bottle with the probe (ensure the
sticky label disc is removed from the
top of the bottle.
3.
If adjusted properly, the red LOW
LED will go out and the green OK LED
will briefly glow. This indicates the
sensor’s heat/sensitivity is adjusted
for optimum performance.
If the red LOW LED remains on when
you briefly touch the bottle, the
sensor heat is set too low and the
Heater Adjustment must be turned
slightly clockwise using a small
screwdriver. Allow unit to stabilize
about one minute and retest. Repeat
