NOTE: For levels less than 10 ppb, it is necessary to run a warm-up routine before
sampling. To initiate the automatic five minute warm-up, install a Zero Air Filter (AZI
P/N Z2600 3905) in the intake and select Warmup from the REGEN menu. Refer to the
Daily Operations section for more information.

1. UNPACKING THE INSTRUMENT
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®J605 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 that have been tested and
proven to be effective protection during shipment.
•Call AZI Customer Service at 800-528-7411 or 602-470-1414 or go to the AZI website
www.azic.com for Return Material Authorization (RMA) information prior to returning an
instrument.
•Boxes and packing materials for all shipments are available from AZI.
•Pack the Jerome®instrument only in a Jerome®shipping container.
AZI WILL NOT BE RESPONSIBLE FOR SHIPPING DAMAGE.
IF YOU RETURN THE INSTRUMENT IMPROPERLY PACKAGED OR
SHIPPED,
YOU SHOULD INSURE IT FOR FULL VALUE.
•Check for any damage and confirm receipt of all parts
on your packing list. Contact Arizona Instrument
Customer Service at [phone] or
[phone] if you have any questions.
•Press the I/O button. The display will light up and
show instrument serial number and software revision.
If necessary, press ESC to clear any calibration
reminders. Call AZI Customer Service or e-mail
[email protected], to schedule instrument
calibration.
•The digital meter displays 0.000 ppm (or 0.00 ppb).
•Look at the battery icon in the top center of the display
to determine the current battery level.
If the battery icon is empty and flashing, recharge
the battery. See page 28.
•The included AC power supply/charger can utilize 110V or 220V AC power, and it is not
necessary to manually select the input voltage.
•The J605 contains an auto-resetting fuse that does not require care, maintenance or
replacement by the user.

AZI Customer Service 800-528-7411 or 602-470-1414 Page 5 of 57
•Perform a sensor regeneration by following these steps:
Connect the AC power supply/charger between the matching (DIN) connector on the back
of the J605 and an AC power outlet or connect the external battery pack to the back of the
J605.
If the J605 is turned off, press the I/O power button to turn the instrument on.
Press the RIGHT arrow button (►) to enter the main menu.
Press the DOWN arrow button (▼) to move the cursor to Regen.
Press the RIGHT arrow button (►) to select Regen from the menu.
Press the ENTER/START button on the keypad to select Regen Now from the Regen
menu.
The instrument will now begin a 45-minute regeneration cycle, indicated by
“Regeneration in Progress” on the display. Do not interrupt this cycle. For a
complete description of this process, see page 23.
If any error message appears on the display, see the J605 TROUBLESHOOTING
section beginning on page 37.
•Ensure the instrument has been powered on for at least five (5) minutes prior to sampling.
•The instrument is now ready to sample.
•The instrument is designed for ambient air monitoring.
•The instrument is not explosion
proof.
•Press the SAMPLE BUTTON at the
end of the handle of the J605 to start a
sampling cycle.
•When the instrument measures
hydrogen sulfide, the 0.000 ppm (or
0.00 ppb) display will be replaced
with a value.
•To ensure the input to the instrument contains no hydrogen sulfide or mercaptans, install a
Zero Air Filter (AZI P/N Z2600 3905) in the intake of the instrument. The Zero Air Filter
cleans the air sample and should produce sample readings of 0.000 ppm (or 0.00 ppb).
Therefore, use the filter to:
Equilibrate the instrument to temperatures that are higher or lower than the instrument.
Sample with the filter installed until the reading is 0.000 ppm (or 0.00 ppb).
Identify contamination within the instrument.
Confirm the presence of hydrogen sulfide when readings are elevated. Install the Zero Air
Filter and verify that the readings go down with the filter installed.
•Perform sensor regeneration before each day’s use.
•Perform another sensor regeneration after each day’s use.
•During periods of storage or inactivity, perform sensor regeneration every 30 days.
Call AZI Customer Service, at [phone] or [phone] if you have any questions.
If you prefer, you may send e-mail to [email protected].
WARNING
DO NOT allow the probe or the instrument’s intake to be exposed to any liquid.
DO NOT obstruct the intake or exhaust ports of the J605, as this could cause errors
in readings and damage to the flow control system.

*Sample values below 3 ppb (0.003 ppm) are recorded and displayed as 0.00 ppb by the J605. Sample
values above 10 ppm (or above the upper limit of the chosen range) are recorded and displayed as “High
Concentration.” “High Concentration” may occur in Auto-range if the gas concentration increases while
the instrument is switching down ranges. In this situation, sample again and use the following result or
lock the J605 in the desired range.

4. PRINCIPLE OF OPERATION
The heart of the J605 is the well-proven gold film sensing technology. A thin gold film, in the
presence of hydrogen sulfide, undergoes an increase in electrical resistance proportional to the
mass of hydrogen sulfide in the sample.
When the SAMPLE button is pressed, an internal pump pulls ambient air over the gold film
sensor for a precise period of time. The gold film sensor adsorbs the hydrogen sulfide, and the
instrument determines the amount adsorbed and displays the measured concentration of hydrogen
sulfide in parts per million (ppm) or parts per billion (ppb) depending on the Range in use.
During normal sampling in Range 1 or 2, the ambient air sample is diluted in the flow system at a
ratio of 100:1.
Initial Pump, Range 1 or 2
Sample Period, Range 1 or 2

AZI Customer Service 800-528-7411 or 602-470-1414 Page 10 of 57
When sampling in Range 0, (where low levels of hydrogen sulfide are expected) undiluted air
samples are drawn across the gold film sensor.
Initial Pump, Range 0
Sample Period, Range 0
The instrument’s microprocessor automatically re-zeroes the digital meter at the start of each
sample cycle and holds the meter reading until the next sample cycle is activated.
During the sample mode cycle, a sensor saturation meter on the LCD represents the percentage of
sensor saturation, or adsorbed hydrogen sulfide collected on the gold film. With use, the sensor
becomes saturated and needs to be cleaned. This is accomplished by a manually activated 45-
minute sensor regeneration cycle, which removes the hydrogen sulfide from the sensor. The
bypass solenoid closes during the sensor regeneration cycle, causing the air to pass through the
scrubber filter, providing clean air for the regeneration process. The closed loop film heat cycle
ensures the sensor is cleaned to its original state. The hydrogen sulfide released during
regeneration is absorbed by the flow system’s final scrubber filter (AZI P/N: Z2600 3930) to
prevent any external contamination from the desorbed hydrogen sulfide. The 45-minute
regeneration process includes a cool-down phase, so the instrument is ready for use as soon as the
regeneration process finishes.
