Setting the Response Reading
1. Screw the regulator into the calibration gas cylinder.
2. If you want to skip adjusting the span setting, press and release the DOWN/NO button. The
display will indicate
Leaving Cal Mode
and the Beacon 110 Rig Monitor will return to normal
operation.
If you want to continue with adjusting the span setting, press and release the UP/YES button.
APPLY
will alternate with
SPAN Gas
on the top display line and the current gas reading will
be on the bottom display line.
3. Turn the regulator’s on/off knob counterclockwise to open it.
When calibration gas is applied, the Rig Monitor will freeze the display gas reading at
the highest level reached while the gas was applied.
4. Allow gas to flow for 2 minutes.
5. Turn the regulator’s on/off knob clockwise to close it. The Rig Monitor will continue to
display the maximum gas response on the display and retain the response level in its memory.
6. Adjust the gas reading up or down to match the calibration gas cylinder concentration by using
the UP/YES and DOWN/NO buttons, then press and release the ENTER button.
7. The Rig Monitor will perform a span operation. The display will indicate
SPAN Gas PASS
for
a few seconds, then indicate
SPAN Gas SAVED
before indicating
Leaving CAL Mode
for a
few seconds.
8. Unscrew the regulator from the cylinder and disconnect the sample tubing from the calibration
cup/splash guard hose barb.
NOTE:
For convenience, leave regulator connected to the sample tubing.
Returning to Normal Operation
1. The display will now alternate between the normal operation screen and the message
REMOVE CAL GAS
for 1 minute. If the calibration gas has not been removed from the
detector, remove it now to avoid unwanted alarms.
During this 1 minute period, the 4 - 20 mA output will remain fixed at 3.5 mA and the
relays will remain in their non-alarm state to avoid unwanted alarms while the
calibration gas clears from the detector. At the end of the 1 minute period, the
REMOVE CAL GAS
message will stop appearing and the Rig Monitor will return to
normal operation.
2. Store the components of the calibration kit in a safe place.
