Caution:
The H-10G is available for operation
on either 110, 120, 220/230, or 240V AC. Operate
the unit only on the proper supply voltage (as
shown on the rating plate); otherwise the unit
could be damaged.
the tip with your finger, then releasing
your finger. If proper flow exists, the
red ball should
noticeably
rise up into
the probe when you uncover the probe
tip. Note that the actual height and
final resting position of the red ball are
not important. See Figure 2.
If the airflow ball does not rise:
-
Tap the probe lightly to ensure
the ball is not sticking.
-
Check the filter in the probe tip,
as described in the
Maintenance
section.
If the flow is still insufficient, then the
unit should be forwarded for repair to
the nearest Authorized Service Center.

the SM(cal) position.
Warning! Personal Injury Hazard
Do not use the H-10G in an explosive or com-
bustible atmosphere. The ambient atmosphere is
drawn through the probe and through the sensor,
which operates at approximately 1000°F (540°C).
The resulting hot mixture of air and combustible
gas could explode.
