Replacing the Sensor
The sensor is a plug-in unit that can
be discarded when expended. It needs
replacing when the H-10G no longer
responds to the calibrate reference
bottle, even with the sensor heat control
fully clockwise. Make sure that the cali-
brate reference bottle contains fluid.
1. Unplug the AC power cord and open
the sensor cover (fig. 1). The sensor
is now visible.
2. Allow the sensor to cool before touch-
ing it (approximately 15 minutes).
3. Unplug and discard the sensor.
4. Insert a new sensor and close the
cover.
5. Set the sensor heat control (fig. 4) to
its 7 o’clock position.
6. Place the unit in operation and
check its sensitivity by following the
procedure in steps 5, 6, and 7 in
the
Operating Instructions
section.
Gradually adjust the sensor heat con-
trol more clockwise until the proper
response is obtained. Each time the
sensor heat control is adjusted, make
only small adjustments either up
or down as appropriate. After each
adjustment: wait about 30 seconds
for the sensor temperature to stabi-
lize; adjust balance knob to 1–3 ticks;
and then re-check the sensitivity.
WARNING!
Personal Injury Hazard
Sensor surface temperature may reach
390°F (200°C) during operation, and may
cause a burn if not allowed to cool.
