3 Operating Instructions

In order to protect the Garnet from water and dust ingress, it must remain in its normal
upright measuring position, even when not in use!!

After use in wet weather, remove standing water from the Garnet using a clean, dry
cloth. Pay particular attention to the LCD/keypad recess and surrounding area.

Always remember that the Garnet Digital Gauge is an accurate measuring instrument
and not a hand tool. It is designed to operate in the railway environment but must at all
times be handled with care!!

During sudden changes in temperature, for example removing the Garnet from a warm
car on a cold day, the Garnet should be left to ‘stabilise’ before it is re-zeroed or used
for measurements!!
3.1 Positioning the Garnet
To maintain integrity of measurement, it is essential that the Garnet be placed on the track such that it
is absolutely perpendicular to the rails. This is achieved by ensuring BOTH measuring ‘feet’ found
on the Groove measuring side of the Garnet are in contact with the running face of the rail.
The Gauge paddle is spring-loaded outwards so it is necessary to retract this paddle before it can be
correctly positioned. Alternatively, and depending on what is being measured, this paddle can be
permanently retracted using the small catch found on the underside of the Garnet.
3.2 Power On
To switch on the Garnet, press the button marked (

) for
approximately 2 seconds. During the start-up process, the equipment
model, and the firmware version are displayed on the screen. After
approximately 10 seconds the initialisation message is replaced with the measuring screen.
If the remaining battery capacity is at 25% or less, a message is
briefly flashed up on the LCD during normal operation to alert the
operator. The frequency by which the message is displayed is
dependent on the remaining battery capacity, i.e. with 20% charge remaining, the battery level will be
displayed every 20 seconds, increasing to every 5 seconds with 5% charge remaining.
