How accurate are the results?
The performance figures are in “G force” units and are accurate to within +/-0.02G

How does the Brake Testa Millennium HV (BTMeHV) work?
The BTMeHV has 3 major components: An accelerometer, a Microprocessor and a Real Time Clock (RTC). By using the data provided by these 3 components during a test, the initial speed, test duration and stopping distance can be calculated. This allows the Brake Performance (in %G) to be determined.
This Brake Performance figure can be compared with statutory requirements, or the vehicle manufacturer’s guidelines.

How is the BTMeHV triggered to commence a test?
The device can be triggered in several ways depending on the type of test being performed. A Pedal Force Transducer (PFT), an optional manual Trigger or the detection of a predetermined deceleration will start the test.

Where is the BTMeHV placed while performing a test?
The unit can be placed on a vehicle seat, on the floor or in a cargo area. The “Direction of Test” arrow must face forward. The BTMeHV should be positioned as near as possible to parallel with the road surface.

How are operator and vehicle details entered into the BTMeHV?
Details are entered using the alphanumeric membrane keypad as prompted on the LCD.

How is the BTMeHV battery recharged?
The battery should be recharged regularly, using only the plug pack supplied.

How often should the battery be charged?
The BTMeHV’s battery is similar to a car’s and therefore should be recharged regularly. Circuitlink recommends overnight charging at least 3 times per week.

How is the BTMeHV cleaned?
The BTMeHV can be cleaned with a soft sponge or rag and with a normal liquid detergent if required. Do not use chemical or petroleum derivatives or abrasives.

What types of printer paper can be used?
Standard printer paper is used. Single print or carbon copy is acceptable.

What type of printer ribbon is used?
Only the correct ribbon for the integral printer should be used. (Usually an “Epson” brand Printer)

Where can replacement printer paper and ribbons be purchased?
Paper and ribbons are normally the only consumables. These can be purchased from any Brake Testa distributor or from most stationery stores.

Can the BTMeHV output deceleration results in different units of measure?
Results can be expressed in G, %G or m/s/s. See the owner’s manual for more details.

How often should the BTMeHV be calibrated?
Check the requirements for your area. Some authorities require calibration every 2 years. Circuitlink recommends an annual calibration routine.

Who can calibrate the BTMeHV?
Calibration can be carried out by any authorised distributor or by Circuitlink International. Calibration normally takes about 1 hour.

Does the BTMeHV have a clock?
The unit has a clock that will output the time and date on all tests performed.

Does the BTMeHV provide a PASS or FAIL report?
The BTMEHV is designed to test a wide range of vehicle types including specialised vehicles that aren’t registered for road use. Because Braking Performance criteria varies greatly between these vehicles, a PASS or FAIL needs to be determined by the operator with reference to local requirements or the vehicle manufacturer’s guidelines.

How are test results shown?
Report can be designed to include operator name, business name or any special ID number etc.

Can repoirts be personalized?
The Brake Testa can be personalized with your name, business name or a special I.D. number.

Does the BTMeHV need to be levelled before carrying out a test?
The BTMeHV will automatically compensate for any test area that runs slightly up or down hill, however the unit should be positioned as near as possible to parallel with the road surface.

What is the maximum angle (slope) on which a test can be performed?
The BTMeHV will automatically compensate for an angle of up to 25 degrees.

What values can the BTMeHV calculate?
• The Slope of the test area is calculated and displayed on the both the LCD and reports.
• The Stopping Distance is calculated and reported.
• The Brake Performance is calculated and reported. This is the result that can be used to determine a PASS or FAIL.

Can the Brake Testa Calculate slope of the road?
Yes, the report can show the road slope that the test was conducted on.

Can the BTMeHV perform other tests?
As well as deceleration tests, the device can be configured to test the closing force of automatic doors on buses, at shopping centres and so on. The BTMeHV can also be configured to test vehicles that have long, slow deceleration rates such as rail and mine equipment.

Can the BTMeHV store test results?
The unit itself can store results for up to 4 tests. The optional Download Smart Module (DSM), which is used to transfer results to a PC, can hold up to 150 tests.

How is test data transferred to a PC?
The DSM is plugged into the unit’s RS232 port and a download made following the LCD prompts. The DSM is then plugged into a DSM interface attached to the PC’s com port. Using Circuitlink’s Link software the results stored on the DSM are copied onto the PC.

Can the unit be powered from the cigarette lighter?
This can be provided as an option.

What warranty period applies to the BTMeHV?
12 months.

Does the unit have an automatic power-down?
The BTMeHV will turn off automatically after about 12 minutes of inactivity.

What is the operational temperature range??
The normal range is -15° to 45° C (5° to 113° F)

What is the operational humidity range?
The maximum recommended relative humidity is 90%.

Can the BTMeHV be used for heavy and light vehicles?
The BTMeHV Millennium is recommended for vehicles weighing over 4500 kg (9900lb) and for specialised vehicles.
For regular testing of light, road-registered vehicles Circuitlink recommends the Brake Testa Millennium or the BrakeCheck.

At what speed is a test performed?
For heavy vehicles, a speed of 15km/h for the Service brake (foot brake) is recommended although any speed in excess of about 8 km/h will provide a legitimate test result.

Will the BTMeHV indicate if a specific wheel has faulty brakes?
The device will indicate the overall Braking Performance, not the performance for an individual wheel.

Can results be reported in different units?
The BTMeHV can be configured for local requirements including metric or imperial measures.

Can the BTMeHV perform an acceleration test?
The BTMeHV can be used to provide an indication of acceleration in terms of G. This test can be affected by various things like gear changes for example. Results should be viewed as approximate and in relative terms only. An absolute result cannot be guaranteed.
