Daily Operations
Before each day's use of the Jerome
®
J605, perform the following steps to verify proper
instrument operation:
•
Press the power I/O button to turn the instrument on.

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 at 800-528-7411 or 602-470-1414, or e-mail support@azic.com , to schedule
instrument calibration.

The digital meter displays 0.000 ppm (or 0.00 ppb, depending on what Range is
currently selected).

Check the battery level as indicated by the battery icon at the top center of the
instrument display.

If the battery meter is empty and flashing, refer to Charging Internal Battery on
page 28 .

If the battery meter is not empty, but is flashing, then the instrument is currently
charging the battery.

When the instrument is plugged in and powered off, the display will stay active
and indicate “Charging.”

To ensure the instrument's electronics have stabilized, allow a 5-minute warm up
before beginning the next step.
•
Perform sensor regeneration. Refer to Sensor Regeneration on page 23 for the procedure.
•
Ensure the instrument has been powered on for at least five (5) minutes prior to sampling.
•
Use the Zero Air Filter to equilibrate the instrument to ambient air temperature.

Install the Zero Air Filter in the instrument’s intake.

Sample repeatedly every 15 seconds until the readings stabilize, then remove the Zero
Air Filter.
•
Press the SAMPLE button (at the end of the handle).
•
At the end of the sampling cycle, read the digital meter.

The number shown on the digital meter is the hydrogen sulfide concentration in ppb or
ppm as appropriate.

This sampled hydrogen sulfide value remains on the display until the next sample is
taken.

The digital meter automatically re-zeroes at the start of each sample.
•
At the end of each day's use, perform sensor regeneration as described in the next section.
DO NOT ALLOW HYDROGEN SULFIDE TO STAY
ON THE GOLD FILM SENSOR OVERNIGHT.
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 .
For levels of 10 ppb and above, the warm-up routine is not necessary.
