WARNING: Personal Injury Hazard
.
D
o not use the RLD-H10G in
an explosive or combustive
atmosphere. The ambient
atmosphere is drawn through the
probe and over the sensor, which
operates at approximately
1000
°
F (540
°
C). The resulting
hot mixture of air and
combustible gas could explode.
!
CAUTION: Equipment Damage Hazard.
To avoid equipment damage,
operate the RLD-H10G on the
proper supply voltage, as given
on the rating plate.
Figure 8: RLD-H10G Faceplate (Sensor heat control
adjustment is on the bottom of the unit.)
1.
Plug the cord into a 120 VAC, 60 Hz outlet.
2.
Flip power switch to “on” position. (See Figure 8.)
3.
Slide range switch to small (“SM”) leak position.
(See Figure 8.)
4.
Check for sufficient airflow by pointing the probe tip
toward the floor and observing the airflow ball in
the probe. (See Figure 9.) If the airflow is
sufficient, the ball will rise and float a small
distance above the tip of the probe. If the ball
does not rise, tap the probe lightly to make sure it
is not sticking. If the ball still does not rise, check
the filter in the probe tip as described in the
Maintenance
section.

5.
Allow two minutes for the sensor to warm up.
When the sensor is warm, the light and sound
indication should idle at around three or four beats
per second. The balance control (see Figure 8)
may be used to adjust the idle rate.
6.
Proceed to the
Calibration and Verification
section.
