Open the catalog to page 3FOR THOSE WHO CAN'T READ THE WHOLE MANUAL NOW This manual contains details that will optimize the results and the life of your instrument. Read and refer to the manual for complete details on operation, maintenance and troubleshooting, special voltage inputs and data output. The Jerome® 631-X is easy to operate and ready for use upon receipt from the factory. • Remove the instrument from the packing material. Retain all packaging materials for any future shipment of the instrument. If the instrument is returned to AZI for any reason, it must be placed in the original packaging materials...
Open the catalog to page 4• Perform a sensor regeneration by following these steps: Connect the line cord between the connector on the back of the 631-X and an AC power outlet. Press the ON switch and then press the REGEN button. The instrument will begin a 10 minute regeneration cycle, indicated by .H.H.H flashing on the display. Do not interrupt this cycle. For a complete description of this process, see page 12. If any error message, such as .P.P.P, appears on the display, see the “Troubleshooting” section beginning on page 24. • When regeneration is complete, zero the sensor by pressing the ZERO button...
Open the catalog to page 5The Jerome® 631-X Hydrogen Sulfide Analyzer is an ambient air analyzer with a range of 0.003 ppm to 50 ppm (parts per million). CAUTION: The Jerome® 631-X is for vapor use only. DO NOT allow the probe or the instrument's intake to be exposed to any liquid, dust or other foreign material. The 631-X is designed to be easy to operate for quick and accurate analysis of hydrogen sulfide vapor levels. It has few maintenance requirements. However, please take a moment to read this manual before attempting operation. If you have any questions about your application or operation, please call AZI...

To change the default voltage range, refer to “Setting the Input Voltage” on page 21. A thin gold film, in the presence of hydrogen sulfide, undergoes an increase in electrical resistance proportional to the...
Open the catalog to page 7Zero Air Filter The Zero Air Filter removes mercury vapor, mercaptans, and hydrogen sulfide from the air sample. Readings with the filter installed should be near zero. Because air that is cooler than the instrument will cause low readings and warmer air will cause higher readings, the Zero Air Filter should be used to equilibrate the unit to ambient air temperature. Continuous sampling with clean air will not cause saturation of the gold film sensor but will equalize temperatures faster to allow accurate analysis to begin sooner. For best results, be sure that the instrument is at the same...

Open the catalog to page 10Daily Operations Before each day's use of the Jerome® 631-X, perform the following steps to verify proper instrument operation: • Press the power ON button. The digital meter displays 000. (Disregard the digital meter's initial momentary reading.) Recharge or replace the battery pack if the LO BAT indicator REMAINS ON. Refer to “Charging Batteries” on page 17 and/or “Replacing the Battery Pack” on page 21. To ensure the instrument's electronics have stabilized, allow a 1-minute warm up before beginning the next step. • Use the Zero Air Filter to equilibrate the instrument to ambient...
Open the catalog to page 11Sensor Regeneration Sensor regeneration is needed to clear the 631-X sensor of any accumulated hydrogen sulfide. This simple procedure should be done: • At the beginning of the day on which the instrument is to be used. • During the day when the sensor becomes saturated. • At the end of the day before storing the instrument. CAUTION: Ensure the voltage selector on the back of the instrument, near the power cord inlet connector, points to the local AC power value. See “Setting the Input Voltage” on page 21. To clean and protect the sensor, the supplied AC power must be 100 to 120 VAC or 220...
