INTRODUCTION

The Guth Model 12V500 Alcohol Breath Simulator is a State-of-the-Art, electroni-

cally temperature controlled, water-alcohol instrument for the purpose of providing

a precise calibration standard for testing or calibration of alcohol breath analyzers.

The Model 12V500 is the rst simulator of its kind to incorporate dual temperature

probes to independently control and monitor the temperature of the solution. The

temperature of the water-alcohol solution placed in the simulator is maintained at

34° C ± .05° C or better. The inlet and outlet port pathways have been designed to

be an integral part of the one piece heated aluminium top housing thus allowing

uniform heating and reduction of condensation. The new LCD graphics display has

a temperature resolution of .01° C and will display simulator status to the user in

the form of messages and status codes. As with all Guth products the 12V500 has

been engineered using the highest quality components to give reliable, accurate and

trouble free operation.

CERTIFIED SIMULATOR SOLUTION STANDARD

PLEASE NOTE: It is imperative your Simulator Solution be of the highest quality in

  ordertoacquirethescienticandlegalstandardsofacceptance.

To establish a precise and accurate calibration standard when using a Guth Simulator,

GUTH LABORATORIES, INC. recommends using Guth Certied Simulator Solu-

tion. Guth Laboratories, Inc., a pioneer and leader in the science of alcohol breath

testing, has provided Certied Simulator Solution to state, municipal, and local law

enforcement agencies for many years.

COMPONENTS & FUNCTIONS

1. TOP HOUSING - The top housing incorporates all the important features

of the simulator. The housing is heated and controlled by use of a head space

heater (U.S. Patent # 8,667,829).

2. LCD DISPLAY - The display indicates the temperature of the solution with

a resolution of .01° C. It also serves to give feedback to the user during use by

displaying status messages. The display is back lighted to allow easy viewing in

all lighting conditions.

3. TEMPERATURE PROBE - The temperature probe consists of two separate

ultra-stable precision thermistor beads. One thermistor bead is used to control

the temperature of the solution at 34° C ± .05° C and the other independently

monitors the temperature of the solution. In the event of either probe failing a

status message is generated on the display.

4. HEATING ELEMENT - The heater element is used to heat the solution to

34° C. It is electronically protected from overheating if the simulator would be

turned on without solution in the container. In the event of a heater failure a

status message will be generated on the display.

5. BAFFLE PLATE - The bafe plate prevents excess solution from entering

the head space or outlet port during a test.

6. AGITATOR - The agitator designed by Guth Laboratories, Inc. stirs the solu-

tion to help maintain a uniform temperature. If the motor fails a status message

will be displayed on the screen.

7. DISPERSION TUBE - A unique dispersion tube disperses the delivery air

uniformly throughout the solution. Tube may be disassembled for cleaning.

8. GLASS CONTAINER - The glass container holds the solution and creates

an airtight seal with the top housing. There is a mark on the container indicating

the solution level at 500 ml ± 5% (#9, Page 3).

10. U.H.C. (Uniform Headspace Conditioner) - To ensure all tests performed

by the Guth Model 12V500 are precise and accurate, an eight (8) blade radial

fan is designed and included in the headspace area. The headspace area is heat-

ed by an imbedded controlled heater. The radial fan provides uniform headspace

heating and the efuent at a constant concentration. Patent Pending.

the external power supply. The 12V500 can be run from the included desktop

switching power supply or any 12VDC source capable of supplying 8 amps.

12. RS-232 COMMUNICATION PORT -The RS-232 port allows the simula-

tor to be interfaced with breath analyzers that support serial communications.

13. POWER SWITCH - The power switch is used to turn the simulator ON/

OFF. It also functions as a RESET switch.

14. CALIBRATION PORT - The calibration port allows the temperature of the

solution to be measured with an external digital or mercury thermometer.

15. FEMALE INPUT CONNECTOR - The standard input connector is a

1/8” ow female SureLoc that allows for easy and secure hook up to various air

delivery methods. (Customized tting options available)

16. MALE OUTPUT CONNECTOR - The standard output connector is a

OPERATING INSTRUCTIONS

1. Unscrew the glass container from the simulator top housing. Pour 500 ml

of Certied Simulator Solution into the container. The Guth laboratory glass

container has a 500 ml ± 5% ll mark.

2.Reassemble the simulator with the glass container. Be sure the container is

properly seated to the top housing. DO NOT OVERTIGHTEN. To check that

the system is airtight cover the outlet port while blowing into the input port. If

back pressure is evident and very few air bubbles are observed emanating from

the dispersion tube the system is airtight.

3. Insert output connector from external power supply to input power jack of

simulator. Insert AC power cord into power supply. Plug power supply into

wall outlet.

4. Turn the power ON. The simulator will beep and the screen shown in gure

1 will be displayed.

5. After approximately 5 seconds the display will change to the screen shown

in gure 2. During this time the simulator will perform an internal diagnostic

check.

6. Figure 3 will be displayed during the warm up cycle. The snow ake icon

indicates that the simulator is still cold and is not ready for use. The temperature

of the solution is displayed in the upper right hand corner of the screen. The

bottom right hand corner shows the status of the top housing temperature.

7. The solution temperature will increase until the set point of 34.00° C has been

attained. When the set point for the top housing is reached the status bar will no

longer blink and will be completely lled to the right (Figure 4).

8. After both set points have been reached there will be a period of approxi-

mately 1 minute before the ready screen will be displayed (Figure 5).

FIGURE 5

9. The simulator will beep indicating that it is ready. It is normal for the simula-

tor to display temperatures in the range of 33.95° C to 34.05° C.

10. Follow the operators manual provided by the manufacturer of the breath

analyzer being used for detailed instructions on how to connect and use the

simulator to perform a calibration or accuracy check. See diagram on next page

for basic hookup and operation.

When manually operating the simulator, take a deep breath and blow

into the mouthpiece rmly and steadily for a 4 to 7 second duration. The blow-

ing technique should imitate a person providing a breath sample into the breath

test analyzer.

Rather than manually blowing into the simulator, the following alterna-

tive means also fulll the requirement of providing air through the tubing at-

tached to the simulator: the breath analyzers internal pump, a simulator bellows

pump, a pump-powered air source, or an atomizer. Several precision models of

pumps are available for purchase through Guth Laboratories, Inc.
