1Introduction

This Calibration Manual details the procedures for performing the calibration of the

Alcolizer LE 5 alcohol breath testing device.

This Calibration Manual is divided into various Sections and Sub-sections to enable the

authorised calibration technician to access the required information with ease. It includes

Cautions and Notes applicable to calibrating the LE 5 device.

IMPORTANT NOTE

Calibration of the Alcolizer LE 5 device should only be performed by a qualified technical person

using certified alcohol solutions dry gas standards.

2Getting Started

Prior to beginning the calibration procedure, ensure the following steps are taken and

precautions adhered too:

Read the entire manual carefully before calibrating the device for the first time.

Ensure the device has at least 3 bars or battery power prior to calibration.

If a dry gas standard is being used, ensure that the gas reference value has being

certified and a certification certificate is attached to the cylinder.

NOTE

Fuel cell sensors have different sensitivity parameters to wet and dry reference gas standards, a

correction factor must be applied when using dry gas as the calibration standard to correctly correlate

with wet gas solution standard.

3Serial Number

Turn the unit on and record the days to cal and the battery bars on the record sheet.

Record the serial number found on the back of the unit onto the record sheet.

Replace any damaged or faded serial number stickers.

4Check Firmware

Enter the ‘About’ menu and press the main button until the unit’s details are

displayed.

The firmware version will be displayed for both the SM and MM. Check that it is the

latest version.

If it is not the latest, update using Alcoconnect toolbox.

Record the number of days until calibration is due if any.

5Alcoconnect

Plug in USB into port on unit

Open Alcoconnect

Type in technician password and press enter

Click on the ‘Technician’menu and then select ‘Check for Firmware Upgrades’

Note: To this function work, the ‘Firmware Upgrade Location’ must be pointing to

the folder with the latest firmware versions.

If outdated firmware versions are detected, select ‘Upload’ to upgrade device.

A code error 32 will in most cases be displayed after update. Reset the unit by

holding down all three buttons at the same time for several seconds then release.

Main screen should appear again.

While still connected to Alcoconnect, sync the date and time to the PC using SET

TIME option.

Note: Upload the firmware first before the date as the firmware change and

change the time and date.

Turn unit off and on again.

Go back into the ‘About Menu and make sure the correct firmware did in fact load.

6Authorisation Calibration Key (AuthKey Cal)

Activate the AuthKey Cal as follows:

Switch on LE 5 unit.

Insert the LE 5 AuthKey Cal USB security key into USB port. The security key symbol

will be displayed on the display screen when the connection is recognised

7Check Unit Parameters –System Check Menu

Check that the serial number in the About menu matches the back of unit

Enter the Special Access Menu, then Enter into the Technician menu, and select the

System Check option.

Back up battery must be at 2.75V or higher

Press the main button on the back up battery option and listen for a good sounding

click.

Attach unit to the manometer and check for leaks. Should be about 11-15mls/L.

Fuel cell temp must be ±2°C that of ambient air temp

Check that the Fuel cell voltage is stable and not fluctuating

Fuel cell voltage should be no less than 0.01V and no more than 0.15V.

Select the ‘Back’ option

8Calibration

8.1 Calibration Gas Value Input

Input the reference gas calibration value into Calibration Gas menu as follows:

Press the Test key to open the Calibration Gas menu input function (refer Figure 1).

Figure 1 - Calibration Gas

Press the Test key again to start input function. The calibration gas first digit value

(underlined) can be changed by pressing either of the Up/down keys to required first

digit number value (refer Figure 2).

Figure 2 - Setting Calibration Gas Value

Press the Test key to accept the entered value and to proceed to the next digit

number input value.

Repeat the above procedure to set and accept each digit’s calibration gas value to

the required (currently used) Wet or Dry gas calibration reference standard e.g.

0.100g/100mL (refer Figure 3).

8.2 Calibrate

Perform calibration as follows:

Install a fresh mouthpiece onto the device

Connect appropriate calibration reference solution to mouthpiece inlet.

Press either of the Up/down keys to scroll to the Calibrate menu function (refer

Figure 4).

Figure 4 –Calibrate

Press the Test key to start the Calibrate process.

The device will display Please Wait… while performing an internal self-check.

After the internal self-check is completed the Ready screen will be displayed (refer

Figure 5 - Self check underway (Please Wait...) and Ready messages



If the self-check is unsuccessful error code 6 will be displayed. If the error code is

shown, consult Alcolizer LE 5 Maintenance Manual).

REF: LE5 Calibration Instructions_Whole Units V5 Page 8 © Alcolizer Technology

Figure 5 - Self check underway (Please Wait...) and Ready messages

Press the Test key to start the calibration sequence. The device displays a

countdown sequence: 13 - 12 - 11 - 10 etc. at one second intervals.

Turn on the calibration gas flow when the count is approximately 10 or 9.

When the countdown reaches 0, the device will take a sample of the calibration gas

and a beep sound will be heard. The Analysing Sample screen will be displayed

(refer Figure 6).

Figure 6 - Analysing Sample message

Turn off the calibration gas flow after the device has taken a sample and the beep

tone has ceased.

NOTE

If the calibration process is unsuccessful, error code 43 will be displayed. Consult Alcolizer

Technology for further technical advice on 1300 789 908.

9Displaying Calibration Results

The results of the calibration are displayed on the screen. The table below describes what

each message means.

The new GAIN needs to be recorded on the data sheet.

Screen Message

preventing calibration of device for the period displayed (refer Figure 7 - Calibration Lockout message).

Figure 7 - Calibration Lockout message

Turn device off and then on.

Enter the ‘About’ menu and press the main button until the unit’s details are

displayed.

Check if device displays the correct remain days to next calibration.

10 Post Calibration Check

It is recommended that a calibration check be performed after a calibration procedure to

verify calibration accuracy. The recommended sequence is:

1st calibration solution test.

1st zero test.

2nd calibration solution test.

2nd zero test.

3rd and final calibration solution test.

For these post calibration checks conducted in normal operation mode.

All readings should be between ±5 percent of the calibration solution value.

Make sure you blow a zero value through the unit as the last test to zero off the screen.

Clean and fully charge all units before returning to the customer.

11 Going Back

To revert back to previous operation screen, perform the following steps:

Press either of the Up/down keys to scroll to the Back menu function.

Press the Test key to revert back to previous menu or operation screen.

12 Additional Information

12.1 Calibration Lock Out

This is a pre-set time period in which a calibration of the device will not be allowed if the

device’s last test was a positive result and the calibration lockout time period from that test

has not elapsed (timed out) (refer Figure 7).

12.2 Dry gas Calibration

As fuel cells have a small sensitivity differential between wet and dry gas readings, a

correction factor must be applied to dry gas calibration values so that correlation between

wet and dry readings are the same.

Consult Alcolizer Technology for technical advice on this issue.

13 Gas Configurations Setup

13.1 Dry Gas setup

The recommended dry gas setup for in-house and field use is as follows

Ensure gas is Dry reference gas 200–220PPM Ethanol (BAC: 0.081-0.090g/100ml).

Turn valve on (1 turn anticlockwise) to commence calibration procedure. Ensure

valve is turned off (clockwise) after completion of calibration procedure.

Ensure blue tube to mouthpiece connection is a friction fit (finger tight).

Set flow-rate on Pre-set flow rate valve to approximately 10-12lts/min.
