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.

AZI Customer Service 800-528-7411 or 602-470-1414 Page 11 of 57
Zero Air Filter (AZI P/N Z2600 3905)
The Zero Air Filter (AZI P/N Z2600 3905) removes hydrogen sulfide, mercury vapor and
mercaptans from the air sample. Readings with the filter installed should be near 0.000 ppm (or
0.00 ppb). For maximum accuracy, wait 15 seconds between samples to allow the sensor to
restabilize.
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 instrument to ambient air.
Repeated 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 maximum accuracy,
wait 15 seconds between samples to allow the sensor to restabilize.
The Zero Air Filter can also be used to identify contamination within the instrument. If the
readings do not reduce to near 0.000 ppm with the filter installed, contamination should be
suspected. If the readings do drop to near 0.000 ppm with the filter installed but elevate with the
filter removed, the presence of hydrogen sulfide at the sampled location is confirmed. Again, for
maximum accuracy, wait 15 seconds between samples to allow the sensor to restabilize.
The Zero Air Filter should be inserted into the intake of the instrument when running the
instrument Warm-up.
For more information on the use of the Zero Air Filter, contact customer service at 1-800-528-
7411 or 1-602-470-1414.

SAMPLE menu
SAMPLE MODE
The Sample Mode setting provides the choice between auto-sampling and manual sampling. For
normal use, use manual sampling, which is the instrument default setting. If auto-sampling is
selected, the instrument will automatically sample at the interval set in SET SAMPLE
INTERVAL (below) without monitoring or attendance by the user. Use the ▲and ▼arrows to
toggle between Manual and Auto, and use ENTER/START to save the selection. Use the ESC
key to exit without saving changes. If auto-sampling is selected, the word Auto will appear below
the system date on the instrument’s main screen.
RANGE
Three different ranges and an Auto-ranging function are available in the J605. If the approximate
value of the expected H2S concentration is known, the instrument can be set into that specific
range prior to sampling (0, 1, or 2). If the expected H2S concentration is not known, Auto-
ranging can be used instead, and the J605 will test each sample in each range before displaying
the concentration. Using Auto-ranging results in longer test times, however accuracy is not
affected. The selected range also determines what units the J605 will use to display the results.
The three ranges and their default display units (ppb or ppm) are shown below:
RANGE
CONCENTRATION
0
3 to 100 ppb
1
0.10 to 1.0 ppm
2
1.0 to 10.0 ppm
The range can be set or Auto-ranging can be toggled on or off by selecting Range from the
SAMPLE menu. Use ▲ and ▼ to scroll through the ranges 0, 1, 2 and Auto, and press
ENTER/START to make a selection. Press ESC to exit without saving changes. The selected
range will be displayed on the main screen as a number (0, 1, 2) or as an Afor Auto-ranging. See
J605 Main Screen Display on page 12 for the location of the Range indicator.
SET SAMPLE INTERVAL
If auto-sampling is being used (as set in SAMPLE MODE above), the sample interval
determines how often the J605 will automatically take samples. Use the ▲and ▼arrow keys to
scroll through the available sample intervals of 1, 2, 5, 10, 15, 30, 45, 60, 90 and 120 minutes, and
use ENTER/START to save the selected interval. Use the ESC key to exit without saving
changes.
The sample intervals refer to specific times on the instrument clock as measured in whole
multiples of the selected interval. For example, selecting a 10-minute sample interval will result

SURVEY MODE
Highlight SURVEY MODE in the SAMPLE menu and press ENTER/STARTto begin
immediate sampling in survey mode. In survey mode, after an initial four-second pause to purge
the flow system, the J605 will sample continuously. For complete information on survey mode,
see Survey Mode on page 25.
REGEN menu
The sensor saturation meter on the main screen (to the right of s. sat) indicates the current level of
saturation of the sensor with hydrogen sulfide.
When the sensor becomes saturated with hydrogen sulfide, as indicated by the sensor saturation
meter, a regeneration (regen) must be performed on the sensor to release the accumulated
hydrogen sulfide, before additional samples can be taken. See Sensor Regeneration on page 23
for more information on the regeneration procedure.
The AC power supply/charger or the external battery pack must be plugged into the back of the
instrument before a regeneration can be performed.
The following options are available from the REGEN menu:
REGEN NOW
Connect external power to the instrument before performing a regeneration.
Highlighting REGEN NOW and pressing ENTER/START will immediately start the sensor
regeneration process. Do not disconnect external power during the regeneration.
WARMUP
To ensure maximum accuracy when sampling at levels less than 10 ppb, the J605 must be
warmed up with the Zero Air Filter in the intake, at the location to be sampled. To run the warm-
up, insert the Zero Air Filter in the intake, highlight WARMUP and press ENTER/START.
While warming up, the pump will run and the J605 will display a 5-minute countdown. When the
warm-up finishes, remove the Zero Air Filter and begin normal sampling. If the J605 is idle for
more than 20 minutes, another warm-up is required to maintain maximum accuracy at these low
levels.

SET INTERVAL
If auto-sampling is being used (as set in SAMPLE MODE above), the J605 can be configured to
automatically perform sensor regenerations at a predetermined interval. Use the ▲and ▼arrows
to scroll through the available intervals of 6, 12, 24, and 48 hours, and press ENTER/START to
save the selected interval. The J605 will now automatically perform a sample followed by a
regeneration every 6, 12, 24, or 48 hours as selected, starting at the time set in SET HOUR
below. Use ESC to exit without saving.
SET HOUR
Use the ▲and ▼arrow keys to select the hour of the day (using a 24-hr clock) to start
regeneration. Press ENTER/STARTto save the setting. At the time set, if auto-sampling is
being used, the J605 will automatically take one sample and then perform a regeneration. This
process will repeat at the interval indicated in SET INTERVAL above. Use ESC to exit without
saving.
NOTE: If the sensor is saturated and a regeneration cycle is performed and completed before the
set hour, the instrument will perform another regeneration at the set hour. However, if the
regeneration cycle does not complete prior to the set hour, the regeneration at the set hour will be
skipped.
DATA menu
Sample data can be stored within the instrument, up to a maximum of twenty thousand (20,000)
data points. On instruments that have the USB Communications option, in addition to viewing
the sample data on the instrument, data can be retrieved from the instrument in one of three ways:
1. SEND TO PC
2. SAVE TO USB MEMORY DRIVE
3. PRINT DIRECTLY TO AN AZI APPROVED PRINTER (AZI P/N: Y990-0098)
The presence of the USB icon on the main screen indicates that the Communications option has
been purchased and that the USB ports are functioning properly. The USB icon will flash during
data transmission. See J605 Main Screen Display on page 12 for the location of the USB icon.
The data is stored in non-volatile memory and will not be affected if the battery is changed or
disconnected.
VIEW STORED DATA
Select VIEW STORED DATA to view previous sample and regeneration history on the screen
of the J605. The Location Name (if specified) corresponding to the data is displayed at the top of
the screen and three sample values at a time are displayed at the bottom of the screen, along with
the time and date the sample was taken. The most recent sample is displayed at the top of the list,
and regenerations are indicated by the word “Regen” instead of a sample value. Use the ▲ and
▼ arrow keys to scroll through the data. If Location Names are used, the Location Name
displayed will automatically update during scrolling to reflect the sampling location of the data
being displayed. The J605 will beep-beep upon reaching the end of the list. After viewing the
data, press ESC to exit and return to the DATA menu.

AZI Customer Service 800-528-7411 or 602-470-1414 Page 19 of 57
On instruments that have the USB Communications option, all of the data is accessible from the
VIEW STORED DATA menu selection. On instruments that do not have the USB
Communications option, only the previous two samples are stored.
SAVE TO USB DRIVE
Before selecting SAVE TO USB DRIVE, connect the target USB memory drive to either USB
TYPE “A” PORT on the back panel of the J605. When ENTER/START is pressed, all of the
