Page 7: Introduction
INTRODUCTION ® The Jerome 431-X Mercury Vapor Analyzer is an ambient air analyzer with a range of 0.001 to .999 milligrams of mercury vapor per cubic meter (mg/m Hg). CAUTION: ® The Jerome 431-X is for vapor use only. DO NOT allow the probe or the instrument's intake to be exposed to any liquid, dust or other foreign material. -
Page 8: Principle Of Operation
Applications • Ambient air analysis • Regulatory compliance • Quality assurance and quality control • Scrubber efficiency testing • Accuracy check for other Mercury Vapor monitors and control systems • Mercury Vapor source detection • Leak detection • Portable Mercury Vapor detection ®... -
Page 9: Zero Air Filter
The sample air passes through a filter (removing any acidic gases which interfere with the sensor's response to mercury) and is drawn over the gold film sensor. The sensor absorbs the Mercury Vapor. Nine seconds after starting, the sample solenoid bypass closes and the remainder of the sample is drawn through the scrubber filter and the flow system. -

Page 16: Operating On Ac Power Or Generator
Operating on AC Power or Generator • For stationary use, the 431-X may be operated on AC power. Operating the instrument on AC power at all times eliminates the need for the battery pack and its necessary maintenance. The battery may be unplugged or removed completely whenever the instrument is operating on AC power. -
Page 17: Charging Batteries
Charging Batteries • Press the power OFF button. • Connect the AC power cord between the 431-X power receptacle and an AC power source. Complete battery recharging takes 14 hours. The 431-X contains a trickle charger so it may be continually plugged into an AC power source without damaging the battery pack. -
Page 18: Maintenance
MAINTENANCE Preventive Maintenance Calendar ® To keep the Jerome 431-X operating at peak performance, follow the maintenance schedule below as a guide. Since maintenance is more a function of application and amount of use rather than time, your requirements may be different from the listed schedule. Call AZI Customer Service at 800-528-7411, 602-470-1414, or e-mail support@azic.com for additional guidance for your environment and operation. -
Page 19: Flow System
Flow System ® The Jerome 431-X's flow system is the crucial link between the sensor and the sample. For the instrument to perform correctly, the flow system must be properly maintained. The user maintainable components of this system are the intake filter (.25 inch fritware), a C/M Filter, two scrubber filters and connecting tubing. -

Page 46: Appendix D - Jerome
® APPENDIX D - JEROME 431-X OPTION FUNCTIONALITY On Non-SMV instruments, the Option Functionality is provided by the Option Circuit Board mounted on the Main Circuit Board. On SMV instruments equipped with the Option Functionality, the Option Functionality is integrated into the Main Circuit Board. Proper use of the Option Functionality requires that the base instrument be fully functional and set correctly for the intended operation. -
Page 47: Instrument Zeroing
Instrument Zeroing ® The Jerome 431-X has three ways to zero the sensor reading before samples are taken if the Option Functionality is installed: (1) The instrument automatically re-zeroes between samples so that each sample is a unique reading. To take a sample, simply press the SAMPLE button. (2) The manually adjusted zero, using the switch on the top of the 431-X, is used to re-establish a baseline between the reference and sensor gold films only after a sensor regeneration. -
Page 48: Timed Regeneration
Timed Regeneration If the unit is to be operated unattended for extended periods, AZI recommends that the sensor be regenerated regularly. Operation under JCS or Data Logger control automatically regenerates saturated sensors. The Option Functionality can control regeneration on a regular basis, every 6, 12 or 24 hours. -
Page 49: 4-20 Ma Analog Output
4-20 mA Analog Output The analog output signal at pin 18 of the 25-pin connector can be configured to provide the instrument's native mode 0-2 Volt output or the optional 4-20 mA output by setting a single jumper. Refer to the tables below for jumper placement. (Pin 23 is the ground pin for the analog output function. -
Page 50: Connection And Setup
® Jerome 431-X instruments shipped after early 1995 are capable of providing 0-2 volts analog output. Instruments shipped before that time can be upgraded by a firmware update and adjustment. Instruments can be upgraded to have 4-20 mA output with the addition of the Option Functionality upgrade. This must be performed at the factory. - Page 51 • The 4-20 mA passive receivers do not contain a voltage source to power the loop current. They require the addition of a separate isolated power supply. Typically a supply that delivers 15 to 20 volts DC at 50 mA is sufficient. Wire these as in Figure 3. Note that some 12-volt DC wall transformers (as used on portable equipment) may deliver 15 to 20 volts when they are lightly loaded.
-
Page 52: Fresh Air Solenoid
Fresh Air Solenoid An external three-way solenoid can be used to provide fresh air or conditioned air during sensor regeneration. This may be necessary if the sample stream lacks molecular oxygen. A low current six volt DC solenoid, connected between pins 19 and 11 of the 25 pin rear panel connector, will be energized during the regeneration cycle if the Option Functionality switch SW100 #6 is placed in the OFF position. -
Page 53: Dc Power Operation
DC Power Operation Instruments with the 431-X Option Functionality can be used with any +12 VDC source for continuous operation, if the AZI Power Inverter Kit, P/N Y031 0902 is purchased. To preserve the life of the DC power source, usually a car or truck battery, the power inverter will switch on automatically to supply the AC necessary for regeneration only. - Page 54 Ensure that the inverter’s power switch is in the “OFF” position. LEAVE the power switch in the “OFF” position at all times. The interface board will activate the inverter when necessary. If the inverter power switch is placed in the “ON” position, it will cause a continuous drain on the external 12-volt power system.
