How often should I charge my battery?
It is okay to leave the unit on charge all the time.

My brake tester will not take charge.

Why is the distance shown on the meter different to that measured with a tape measure?
AutoStop brake meters measure deceleration (braking efficiency) directly (which is the design parameter used in original homologation) to an accuracy of 2%. Distance is calculated by the meter in its internal computer using the average deceleration measurement, time to stop (from the internal real time clock – accuracy 1.0%) and the assumption that the final speed is zero. The double integration process involved in the mathematics compounds these measurement accuracies and dependent on the shape of the deceleration versus time trace can generate a different result. The difference will be much less than that obtained from using any peak deceleration instrument such as a Tapley meter. The difference is due solely to the mathematics and is not a function of the AutoStop meter. Regulators in certain jurisdictions still use “distance to stop” – because in the 70’s and 80’s direct measurement of braking efficiency to an accuracy of 2%. The regulations will “catch-up” eventually.

Can I store two tester ID numbers in the meter?
No, only one ID can be stored. Please press “N” on the
Examiner ID prompt to reset it.

How long does my warranty last?
12 months parts and labour. 3 months parts and labour for repairs.

Why the Brake Meter turns off while printing, even it has been charged overnight?
The battery is not holding charge and needs to be replaced.
Send it in to us for a replacement.

The charging light is not tuning on when I plug in the charger.
The charging socket may be damaged, or the LED may be blown. Send it in to us for repair. Please also send in with the charger you are using.

The Brake meter turns off in the middle of a test or print out, but it shows 100% battery.
The battery is not holding charge and needs to be replaced.
Send it in to us for a replacement.

Why the keypad shows 12V input but I need to use a 14V charger?
That means 12V non-regulated. It should be shown as 14V if the charger output is regulated. We recommend using the charger that came with the Brake Meter only.
Never use a 12V regulated charger, it will drain the battery. You can purchase a new charger through our website or your local distributor.

The charging light is not going off even when the battery is fully charged.
The charging light only indicate if a charger is plugged in, it won’t change according to the battery level.

Please install the USB drivers included with the Brake Meter software, these are located in the ‘USB drivers’ sub-folder of the main folder where the datalogger was installed to (Typically: C:\Program Files (x86)\AutoTest\Maxi and Heavy Datalogger).
Please contact us for further assistance if this still doesn’t recognise your Brake Meter.

How do I find which Comm Port number my Brake Meter was assigned?
Open ‘Device Manager’ and expand ‘Ports(Com & LPT)’.
Search the list of devices for ‘USB Serial Device’ and to the right of its name will be the Com port number.

How do I use my Brake Meter with serial connection with newer desktops or laptops that don’t have a serial ports?
It is still possible to use a Brake Meter with serial connection on newer PCs that lack serial ports by using a USB-to-serial converter. Compatibility with individual converters may vary however and AutoTest can only offer minimal support in assisting you when using one.
