65-2443SS-XX PPM Hydrogen Transmitter • 17
Materials
• 0.5 LPM fixed flow regulator with an on/off knkob
• calibration cup
• humidifier tube
• calibration gas cylinder with a full-scale concentration
• calibration gas cylinder with a half-scale concentration
Preparing for Calibration
1. Screw the calibration cup onto the bottom of the hydrogen detector.
2. Use the humidifier tube to connect the regulator to the calibration cup.
3. Set a voltmeter to measure in the millivolt (mV) range.
4. Remove the junction box cover, then plug the voltmeter leads into the test points on the amplifier.
Plug the positive lead into the red + test point; plug the negative lead into the black - test point.
5. Place the controller into its calibration mode or disable external alarms.
NOTE: Calibrating the ppm hydrogen transmitter may cause alarms. Be sure to put the controller into
its calibration program or disable external alarms before continuing.
Setting the Zero Reading
The detector’s zero setting is controlled by electronics and is not user-adjustable.
