Page 5: Overview
WARNING: When using the 65-2443SS, you must follow the instructions and warnings in this manual to assure proper and safe operation of the 65-2443SS and to minimize the risk of personal injury. Be sure to maintain and periodically calibrate the 65-2443SS as described in this manual. -
Page 6: Description
The leads allow you to connect the detector to the amplifier. The detector has a built in molecular sieve that only allows hydrogen to diffuse into the detector. The output of the detector is non-linear and is linearized by the amplifier (see below). 6 • 65-2443SS PPM Hydrogen Transmitter... -
Page 7: Amplifier
The linearizing pot (labeled LINEAR) is located in the bottom left corner of the amplifier (see Figure 2). Use a small flat blade screwdriver to turn the linearizing pot’s adjustment screw while applying mid-scale gas to linearize the transmitter’s output during the calibration procedure. 65-2443SS PPM Hydrogen Transmitter • 7... -
Page 8: Junction Box
Use the cover on the front of the junction box to access the interior of the junction box. The detector and amplifier are factory installed in the junction box. A locking set screw on the junction box cover allows you to secure the junction box cover and prevent it from being removed. 8 • 65-2443SS PPM Hydrogen Transmitter... -

Page 10: Wiring The Ppm Hydrogen Transmitter
10. Route the cable or wires leading from the ppm hydrogen transmitter through one of the conduit hubs at the controller housing. CAUTION: Do not route power and transmitter wiring through the same controller conduit hub. The power cable may disrupt the transmission of the transmitter signal to the controller. 10 • 65-2443SS PPM Hydrogen Transmitter... - Page 11 12. If shielded cable is used, connect the cable’s drain wire to an available chassis (earth) ground at the controller. RKI controllers typically have a ground stud that can be used to ground the cable’s drain wire. 65-2443SS PPM Hydrogen Transmitter • 11...

14. Allow the replacement detector to burn-in for at least 5 days before you continue with the next step. A burn-in period of 7 days is recommended. 15. After the burn-in period, calibrate the transmitter as described on page 16. 14 • 65-2443SS PPM Hydrogen Transmitter... - Page 15 Be sure to make arrangements so that this does not cause unwanted alarms. 9. Turn on power to the controller. 10. Turn on the controller and place it into normal operation. 65-2443SS PPM Hydrogen Transmitter • 15...

Page 16: Calibration Frequency
Although there is no particular calibration frequency that is correct for all ppm hydrogen transmitter applications, a calibration frequency of every 6 to 12 months is adequate for most applications. Unless experience in a particular application dictates otherwise, RKI Instruments, Inc. recommends a calibration frequency of every 6 months. -
Page 17: Preparing For Calibration
4. Verify a reading of 300 mV (±2 mV) on the voltmeter. If necessary, use the linear pot on the amplifier to adjust the reading. 5. Turn the regulator knob clockwise to close the regulator. 6. Unscrew the regulator from the 1,000 ppm H calibration cylinder. 65-2443SS PPM Hydrogen Transmitter • 17... -
