3M™ Compressed Air Filter and Regulator Panel W
3M™ Compressed Air Filter and Regulator Panel W-2806/07006 Calibration
The 3M™ Calibration Kit is available in two sizes. The large kit (part 529-04-48
automotive part 75787) will allow you to complete approximately 36 calibrations.
The small kit (part 529-04-49/ automotive part 72012) will allow you to complete
approximately 10 calibrations.
1. To zero the monitor:
a. Remove the protective cap from the ZERO AIR cylinder outlet.
b. Connect the plastic tubing provided in the kit to the plastic fitting and
connect the opposite end of the tubing securely to the barbed fitting on
the regulator.
c. Connect the monitor's sample tube to the proper end of the
tubing/regulator assembly, described in the previous step.
d. Locate the ZERO adjustment potentiometer and verify monitor has had
adequate warm-up time (see 3M™ CO Monitor User Instructions).
e. Screw the regulator valve onto the ZERO AIR cylinder outlet, making
sure not to "cross thread" the regulator or cylinder outlet port, and
tighten the regulator firmly. Open the knob on the regulator
counterclockwise to start gas flow.
f. Observe the display on the monitor. The reading should move to zero
(00) after approximately one (1) minute. If the display does NOT read
zero (00), adjust the ZERO potentiometer such that the display now
reads zero (00).
g. When these steps have been completed, close the knob on the
regulator clockwise to stop gas flow. Unscrew the regulator valve from
the ZERO AIR cylinder and replace the plastic protective cap.
h. Disconnect the associated calibration test tubing from the monitor and
reconnect the monitor’s sample tube to the sampling supply on the
filtration system.
i. NOTE: When using the small kit, be aware that the regulator valve
allows gas to flow from the cylinder as soon as it is tightened down. To
conserve the gas in the cylinder do not attach the regulator valve until
you are ready to begin zeroing, and remove the valve as soon as
zeroing is complete.
2. To span the monitor:
a. Remove the protective plastic cap from the SPAN GAS cylinder, noting
the concentration of carbon monoxide printed on the cylinder.
b. Connect the plastic tubing provided in the kit to the plastic fitting, and
connect the opposite end of the tubing securely to the barbed fitting on
the regulator.
c. Connect the monitor's sample tube to the proper end of the
tubing/regulator assembly, described in the previous step.
d. Locate the SPAN adjustment potentiometer and verify the monitor has
had adequate warm-up time (see CO Monitor's User Instructions).
e. Screw the regulator valve onto the SPAN GAS cylinder outlet, making
sure not to "cross thread" the regulator or cylinder outlet port, and
tighten the regulator firmly. Open the knob on the regulator
counterclockwise to start gas flow.
f. Observe the display on the monitor. The reading will increase, and
then stabilize. As soon as the reading is stable (approximately one
minute), compare the value indicated on the display, with the value
noted on the SPAN GAS cylinder. If the display does NOT read the
same value as noted on the SPAN GAS cylinder, adjust the SPAN
potentiometer until the reading indicated on the display matches the
concentration of carbon monoxide printed on the SPAN GAS
calibration cylinder.
g. When these steps have been completed, close the knob on the
regulator clockwise to stop the gas flow. Unscrew regulator valve from
the SPAN GAS cylinder and replace the protective plastic cap.
h. Disconnect the associated calibration test tubing from the monitor and
reconnect the monitor's sample tube to the sampling supply on the
filtration system.
i. When using the small kit (part number 529-04-49 or automotive part
number 72012), be aware that the regulator valve allows gas to flow
from the cylinder as soon as it is tightened down. To conserve the gas
in the cylinder, do not attach the regulator valve until you are ready to
begin spanning the monitor and remove the regulator valve as soon as
spanning is complete.
This concludes the Filter & Regulator Panel with Carbon Monoxide Monitor
Training.
