1 INTRODUCTION TO THE JEROME 651
The Jerome 651 is a non-portable hydrogen sulfide gas monitor designed for perimeter
and other outdoor locations. The 651 utilizes a removable 631-X to monitor gas
concentrations. The 651 is protected in an insulated all-weather (except flooding)
enclosure; it is AC powered and has built-in heat and air-conditioning for increased
631-X accuracy. The 651 can be remotely polled for up-to-date readings or left
unattended to log readings for up to a year. A PC that is equipped with “Jerome Monitor
Software” (JMS) and a radio modem serves as a Base Station and downloads readings
from one or multiple 651’s; the software graphs and reports the data. The 651 is set up
at the unit through a menu driven interface and the software can remotely configure the
sample and sensor regeneration intervals. The entire system is designed to help
monitor H2S odor compliance.
This manual contains details that will optimize the results and the life of your Jerome
651. Read and refer to the manual for complete details on operation, maintenance and
troubleshooting.
The Jerome 651 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 AMETEK
Brookfield 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 Customer Service for Return Material Authorization (RMA) information prior to
returning a unit.
•For all shipments, boxes and packing materials are available from AMETEK
Brookfield.

2 WARNINGS (READ THIS BEFORE USING THE 651)
•THE 651 IS NOT DESIGNED TO OPERATE IN
HAZARDOUS LOCATIONS.
•THE 651 IS DESIGNED FOR ODOR MONITORING
OF HYDROGEN SULFIDE.
•Read the “631-X Operation Manual” (P/N 700-0037) for specifics on the 631-X.
•Sample intervals under 30 minutes will result in a 631-X sensor life of less than 1
year.
•Follow local and national codes when installing the 651.
•It is recommended to use a ground fault circuit interrupter (GFCI) on the AC power
circuit for safety in an outdoor environment.
•Do not allow rain to get inside the enclosure.
3 631-X
•In the 651, the 631-X used has been modified to allow remote control of the keypad.
A DB9 connector on the back panel allows the 651 to control the 631-X.
•If the 631-X sample button is pressed, the reading is logged by the 651.
Do not use any other 631-X button.
•For maintenance and calibration, the 631-X is easily removed from the 651. An
additional 631-X (P/N X631-0151/-0152) can be purchased to keep the 651
operating when you send in a 631-X for calibration.
•To remove the 631-X:
➢Disconnect the AC power for safety. If the 651 is left on, the “631 System Error”
occurs on the 651 when a sample is attempted. To clear the error, reset AC
power or wait for the 631-X to stop sampling and select the 651’s SYSTEM /
RESET menu item.
➢Loosen the 631-X nozzle and pull the elbow fitting out.
➢Disconnect the power and data cables from the 631-X.
➢Use a quick tug to remove the 631-X from the 651.
➢Reverse the procedure to reinstall the 631-X.
•When replacing the 631-X, the clips that hold the 631-X in the 651 may need
adjustment. Loosen the three (3) screws for one of the clips and adjust it, so the
631-X snaps in place. If necessary, adjust the second clip as well.
•When the 631-X is calibrated and installed back into the 651, a new VACUSHIELD
filter (P/N 800-0065) must be installed in the 651.
•The serial number of the new 631-X must be entered into the 651 using the
SYSTEM / ID / 631 SN menu selection at the 651.
•The 631-X’s battery pack is internally disconnected to lower heat generation in the
651. To use the 631-X outside of the 651, re-connect the battery pack and connect

7.2 Power Connection
POWER CONNECTION NOTES:
•When a generator is used to power the 651, a high-quality line conditioner or voltage
regulator is required to ensure a pure sine wave and regulated voltage is applied to the
instrument. The gold film sensor may be damaged by voltage that varies in amplitude or
by surges, spikes, and/or noise on the power line.
•Follow appropriate local and national codes when installing the 651.
•It is recommended to use a ground fault circuit interrupter (GFCI) on the 115V or 220V
AC power circuit for safety in an outdoor environment.
•For fixed-point installations where an FTM (P/N Z2600 0930 or Z2600 0918) is going to
be used to verify the operation and compliance of the system, the installation of a
weatherproof electrical receptacle near the monitoring system is recommended.
The 651 power voltage is not switch-able in the field. The 651
is factory configured to operate at either 115VAC or 230VAC.
The switch on the main circuit board indicates the proper
voltage and cannot be changed by the user.

Customer Service 800-528-7411 or 602-470-1414 Page 11 of 68
POWER CONNECTION PROCEDURE:
1. Ensure the facility circuit breaker for the power
line is open.
2. Connect the two power lines and the safety
ground as shown.
3. Close the circuit breaker and the 651 is powered.
•At power UP, the display flashes in order:
➢AMETEK,
➢MONITOR,
➢VX.XX, where X.XX is the version number
of the 651’s operating program, and
➢X.XXXPPM, where X.XXX is the detected
concentration
of the monitored gas.
7.3 Wind Gauge
The optional Wind Gauge can be utilized to track wind speed and direction at sites
where a weather station or similar system is not available.
INSTALLATION:
•Confirm that the SYSTEM / WIND / ENABLE menu item is set to YES.
•Run the “Wind Gauge Cable” into the hole at the bottom of the 651, and seal the
cable entry with the “Grommet” (P/N 350-0128). If desired, cut the excess cable and
install a new modular jack; ensure that the new jack is put on in the same direction.
•Connect the “Wind Gauge Cable” to the “651 Control Circuit Board” using the “651
Wind Gauge Cable” (P/N 200-0137).
•Install the Davis anemometer according to the Davis installation manual. When
attaching the wind vane, use the 651’s “WIND DIR” status item to view the current
directional reading. Refer to §9.1 Status Items to view status items.
SETUP:
•Using a magnetic compass, select a fixed direction (such as North).
•Turn the directional potentiometer at the top of the Davis anemometer until the
display inside the 651 reads the selected fixed direction (e.g. North).
•Carefully install the directional vane on top of the anemometer and secure by
tightening the Allen screw.

8 BASE STATION
The radio modem uses a 2.4 GHz frequency, so the radios may not penetrate a
building. To get the best range between the 651 and the Base Station, the antennas
should have a direct line of sight. An outside roof mount is desirable for the Base
Station antenna. However, for an outside antenna, a lightning arrestor and a ground
strap are required for safety.
The Nano (with RP-TNC adapter) and Spectra radios have a RP-TNC-Jack connector.
The external antenna and lightning arrestor have N-Female connectors.
See §6 OPTIONAL EQUIPMENT for a complete list of radio modem accessories.
8.1 Base Station Setup
•Attach the antenna to the base station radio
modem as shown. If an outdoor antenna is
going to be used instead, see the notes at the
end of this section.
•If the green terminal block does not have a
power supply already attached to it, then test the
power adapter wires with a multimeter to
determine the ‘+’ and ‘-‘ wires, and connect the
wires to the Vin+ and GND positions
respectively.
•Connect the green terminal block to the radio as
shown and plug the AC/DC power adapter into
an AC power outlet. Always have an antenna
connected when the radio is powered.

Customer Service 800-528-7411 or 602-470-1414 Page 15 of 68
•Attach the serial communication cable to the
radio modem’s serial port and the PC’s serial
port. Modern PC’s don’t typically have a serial
port. If necessary, install a serial card (StarTech
16950 UART card is preferred) or use a USB to
RS232 adapter (P/N 990-0238).
•Install Jerome Monitor Software (JMS) to monitor the 651 instrument(s). See §11
JEROME MONITOR SOFTWARE (JMS) INSTALLATION for instructions.
INSTALLATION NOTES:
•If the base station antenna cannot be located in the ‘line-of-sight’ of a 651 or the 651
is out of range, a repeater can be used. If the 651 cannot be located within range of
the base station, the Jerome 651 can run remotely and store up to 50,000 readings.
•If an outdoor antenna is used on the base station:
➢Connect an appropriate cable between the radio modem and the lightning
arrestor. Refer to §6 OPTIONAL EQUIPMENT for information on the different
available cables.
➢Next, connect an appropriate cable from the lightning arrestor to the outdoor
antenna. See the diagram on the next page for an example setup.
➢The lightning arrestor must be grounded to provide protection. Use the
Grounding Strap to ground the lightning arrestor to a metal water pipe running
into the ground, grounding spike, or other appropriate means using #6 gauge
bare copper wire. (Follow national/local codes). See the pictures on the
following pages for assistance configuring the Grounding Strap.
➢For additional protection, install a lightning rod as well to protect the system.
