1.
Screw the calibration cup onto the bottom of the detector you wish to calibrate.
NOTE:
If you can verify that the multi-point detector is in a fresh air environment, you
do not need to apply zero air to the detector before adjusting the zero reading.
2.
Screw the regulator into the zero air calibration cylinder. Make sure the regulator is
off. It is off when the on/off knob is turned all the way clockwise.
3.
Use the calibration kit sample tubing to connect the fixed flow regulator to the
calibration cup.
4.
Put the controller into its calibration program. See the controller operator’s manual
for instructions to enter the calibration program.
NOTE:
RKI controllers have a minimum hold feature for zero adjustment and a peak
hold feature for span adjustment. Because of this, the instructions call for turning
off the gas to a detector before making adjustments.
Setting the Zero Reading
1.
Follow the directions in the controller operator’s manual for setting the zero reading.
2.
When the instructions call for applying zero air to the detector, turn the regulator’s
on/off knob counterclockwise to open it. Gas will begin to flow.
3.
Allow the gas to flow for two minutes.
4.
Turn the regulator’s on/off knob clockwise to close it.
5.
Set the zero reading according to the controller operator’s manual.
6.
Unscrew the regulator from the zero air calibration cylinder. Leave the sample tubing
connected to the regulator and the calibration cup.
Setting the Response Reading
1.
Screw the regulator into the calibration gas cylinder. Make sure the regulator is off. It
is off when the on/off knob is turned all the way clockwise.
NOTE:
Ensure that you are using an appropriate calibration cylinder for the channel you
are calibrating.
2.
Follow the directions in the controller operator’s manual for setting the response
reading (span).
3.
When the directions call for exposing the detector to gas, turn the regulator’s on/off
knob counterclockwise to open it. Gas will begin to flow.
4.
Allow gas to flow for 2 minutes before continuing with the directions.
5.
Turn the regulator’s on/off knob clockwise to close it.
6.
Set the response reading according to the controller operator’s manual.
7.
Unscrew the regulator from the cylinder.
