NOTE: Make sure the bottom ferrule is laying flat in the nut.
4. Insert the cone-shaped front ferrule on top of the bottom ferrule. Insert the ferrule so
the smaller end of the cone is facing up.
5. Screw the nut onto the fitting, then connect the sample tubing to the fitting. Make sure
you firmly tighten the tubing to the fitting.
Calibration
This section describes how to calibrate the Model 1017-01. It includes procedures to
prepare for calibration, set the zero reading, set the response reading, and return to
normal operation.
The standard calibration gas for the Model 1017-01 is methane. The Model 1017-01 may be
calibrated to other combustible gases such as hexane or hydrogen. Use the correct
calibration gas for your installation.
NOTE: Calibrating the Model 1017-01 may cause alarms. Be sure to put the controller
into its calibration program or disable external alarms before continuing.
NOTE: This procedure describes calibration using a demand flow regulator.
Preparing for Calibration
1. Follow the instructions in the controller’s operator’s manual for entering calibration
mode.
2. Screw the regulator into a zero air calibration cylinder.
NOTE: If you can verify that the Model 1017-01 is in a fresh air environment, you do not
need to apply zero air to the detector before setting the zero reading.
Setting the Zero Reading
1. Connect the sample tubing from the demand flow regulator to the Model 1017-01’s
inlet line. This step is not necessary if you verified a fresh air environment earlier in
this procedure.
2. Allow the Model 1017-01 to draw sample for one minute.
3. Follow the directions in the controller’s operator’s manual for setting the zero
reading. If you used a zero air calibration cylinder to set the zero reading, proceed to
step 4. If you verified a fresh air environment, proceed to the next section, Setting the
Response Reading.
4. Disconnect the sample tubing from the inlet line.
5. Unscrew the regulator from the zero air calibration cylinder.
Setting the Response Reading
1. Screw the regulator into the combustible gas calibration cylinder.
2. Connect the sample tubing from the demand flow regulator to the Model 1017-01’s
inlet line.
