NOTE: For EPA clean-up levels less than 3 μg/m3, 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®J405 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 a
unit.
•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
(602) 470 -1414 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 at
800-528-7411 or 602-470-1414, or e-mail
[email protected], to schedule instrument
calibration.
•The digital meter displays 0.00 μg/m3(or 0.000 mg/m3).
•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 J405 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 6 of 61
•Perform a sensor regeneration by following these steps:
Connect the AC power supply/charger between the matching (DIN) connector on the back
of the J405 and an AC power outlet or connect the external battery pack to the back of the
J405.
If the J405 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 respond with “Perform Regen Using EXTERNAL POWER?”
Press ENTER/START to proceed or ESC to exit.
The instrument display will warn “Do Not Disconnect External Power while Heating”.
Press ENTER/START to proceed or ESC to exit.
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 “Troubleshooting” section
beginning on page 38.
•Ensure the instrument has been powered on for at least five (5) minutes prior to sampling.
•The instrument is now ready to sample.
•Press the SAMPLE BUTTON at the end
of the handle of the J405 to start a
16-second sampling cycle.
•When the instrument measures mercury
vapor, the 0.00 μg/m3(or 0.000 mg/m3)
display will be replaced with a value.
•To ensure the input to the instrument
contains no mercury vapor or mercaptans, use a Zero Air Filter (AZI P/N Z2600 3905). The
Zero Air Filter cleans the air sample and should produce sample readings of 0.00 μg/m3(or
0.000 mg/m3). Therefore, use the filter to:
Equilibrate the instrument to temperatures that are higher or lower than the instrument.
Sample every 15 seconds with the filter installed until the reading is 0.00 μg/m3(or
0.000 mg/m3).
Identify contamination within the unit.
Confirm the presence of mercury vapor when readings are elevated. Install the filter and
verify that the readings decrease with the filter installed.
•The instrument is designed for ambient air monitoring.
•The instrument is not explosion proof.
•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 J405, as this could cause errors
in readings and damage to the flow control system.

2. INTRODUCTION
The Jerome®J405 Mercury Vapor Analyzer is an ambient air analyzer with a range of 0.5 to 999
micrograms of mercury vapor per cubic meter (µg/m3Hg).
CAUTION:
The Jerome®J405 is for gaseous 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 J405 is designed to be easy to operate for quick and accurate analysis of mercury 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 Customer Service at [phone] or [phone] or e-mail
[email protected] for assistance.
J405 Features
•Much lower detection levels than the previous Jerome®models.
•3 ½ inch (9 cm) backlit display, showing everything you need to be confident in the
instrument, including 5/8 inch (1.6 cm) tall character readout, battery charge indicator,
and sensor saturation percentage.
•Choice of units for results: micrograms per cubic meter (µg/m3) (default) or
milligrams per cubic meter (mg/m3).
•Easy to understand diagnostic and error detection.
•Auto zero bridge adjustment.
•Updated electronics including 24-bit a/d conversion and on-board storage for 20,000
samples.
•Controlled temperature film heat ensures the sensor removes all mercury and returns
to its original state.
•The Jerome®J405 can be operated for 24 hours from the internal 12V battery source
or it can be operated using the external AC power supply/charger.

4. PRINCIPLE OF OPERATION
The heart of the J405 is the well-proven gold film sensing technology. A thin gold film, in the
presence of mercury vapor, undergoes an increase in electrical resistance proportional to the mass
of mercury vapor in the sample.
When the SAMPLE button is pressed, an internal pump pulls ambient air through a scrubber filter
(AZI P/N: 600-0262) and into the flow system.
After three seconds, the sample solenoid bypass opens, closing off the scrubber filter from the
flow system.
The sample air passes through the AG filter (AZI P/N: 600-0293), an acidic gas filter that
removes any acidic gases that interfere with the sensor's response to mercury. Then the sample
air is drawn over the gold film sensor. The sensor adsorbs the mercury vapor. Eleven seconds
after starting, the sample solenoid bypass closes and the remainder of the sample is drawn through
the scrubber filter and the flow system. The instrument determines the amount of mercury
adsorbed and displays the measured mercury concentration on the digital meter in micrograms per
cubic meter (µg/m3) or milligrams per cubic meter (mg/m3) of mercury.
