1 Introduction
The Geismar Garnet is a portable, lightweight, hand operated digital track gauge for measuring the
following seven track parameters:-
Gauge
Cross-level
Groove Clearance
Checkrail to opposite Running-rail
Running-rail to opposite Check-rail
Back-to-back Check-rail
Twist
1.1 Packing List
The Garnet is supplied with the following components. If any of these items are missing then contact
your local Geismar representative.
Track Gauge
Mains Battery Charger
Operating Manual
Calibration Certificate
1.2 Initial Instructions
The Garnet track gauge is fitted with an internal Ni-MH battery. Before the instrument is first used,
the battery must be fully charged using the procedure described in Chapter 5 of this manual.

2 System Controls
The Garnet has three buttons on its front panel as shown here. Many of the measuring modes are
selected automatically and an explanation of these modes and manually selected functions are detailed
in the following sections. The diagram below identifies these controls along with the other major
components found on the Garnet.
2.1 Switching On
The button marked () should be pressed for a period of approximately 2 seconds, this will run a
system test and then start the gauge operating.
2.2 Switching Off
Pressing both buttons (+

) simultaneously for 5 seconds will switch off the gauge. Alternatively,
if the auto ‘Power Off’ option has been enabled, then the gauge will automatically switch off after a
preset time of inactivity. This is detailed in the ‘Software Menus’ section of the manual..
2.3 Control Buttons
These two buttons are marked () and (

) and are used to operate the Garnet. Their functions
change depending on the current mode, but in most cases contextual help is provided to aid the user.

2.4 Backlight
With the Garnet in measuring mode, pressing the () button will either will activate the LCD
backlight, for a pre-determined period, or toggle the backlight on and off. This is detailed in the
‘Software Menus’ section of the manual.
2.5 Contextual Help Icons
To assist the user in menu navigation, the Garnet makes use of on-screen contextual help icons. These
appear on the LCD alongside the relevant control button (or

) to remind the operator of their
function. Commonly used icons and an explanation of their meaning are listed below:-
() OK or Enter
() Scroll through option
() Next menu
2.6 DC Charging Socket
This socket is used for charging the battery and can be found on the underside of the Garnet. A battery
charger is provided with the Garnet and instructions on charging are covered in Chapter 5 of this
manual.
GAD04DOC820Ver9 - en.docx 7

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.

3.3 Intuitive Measuring Mode Selection
The Garnet is fitted with a high accuracy inclinometer, and two measuring ‘paddles’ enabling it to
measure up to seven track parameters. In order to maintain measurement integrity and improve ease
of use, the Garnet records the most extreme (max or min) value measured in the selected direction,
even if this is not the current value.
In the case of the Gauge paddle, a change in direction (and hence a change in measuring mode) will
only be acknowledged if the paddle movement exceeds 5mm in the opposite direction.
In the case of the Groove paddle, the maximum value will be stored until the paddle movement
exceeds 5mm in the opposite direction if Groove Latch is [Disabled], or if the user manually exits that
measuring mode by pressing the (

) button if Groove Latch is [Enabled]. See ‘Software Menus’.
3.4 Measuring Modes
The Garnet uses ‘intuitive measuring mode selection’ to determine which measurement(s) the
operator is attempting to make, based whether the paddles are being moved ‘In’ towards or ‘Out’
away from the track centre. The table below illustrates how the different measuring modes are
selected:-

In the case of the Gauge paddle, a change in direction (and hence a change in measuring mode) will
only be acknowledged if the paddle movement exceeds 5mm in the opposite direction.
In the case of the Groove paddle, the maximum value will be stored until the user manually exits that
measuring mode by pressing the (

) button (if Groove Latch is on) or if the paddle movement
exceeds 5mm in the opposite direction (if Groove Latch is off).
