The clip on battery pack attaches onto the base
of the handle and provides power for additional
4-6 hours.
The Desktop charger will recharge the battery in
about 1.5 hours.
The VChange sensor system allows sensor heads
to be quickly and easily changed without using
any tools. The Vchange system can be retrofitted
to existing MX+ handles and sensors. Sensor
heads can be freely interchanged between
different handles.
To swap the sensor head squeeze the orange
release tabs on the Vchange collar and pull the
sensor off the handle. Push the new sensor into
place until the collar lock clicks. The sensor can
be swapped without turning off the GapGun.
The GapGun Pro has an internal battery which can
power the GapGun for 4 to 5 hours of normal use.
The battery can be recharged using the docking
station or via the clip-on battery which can be used to
extend the period of use by a further 4-6 hours.

Some heads have a three position mask in front of the laser. Turning the laser cap changes the mask:
Position I places a mask line in the centre of the laser line. This artificially divides the laser line into a left and
right side. It can be used to measure features where it is difficult to identify the left and right sides
of a feature.
Position II is the default position which allows the full width of the laser line to be used.
Position III masks the laser on the right and left ends of the line presenting a shorter laser line on the feature.

The Docking Station connects the GapGun to the PC
though an Ethernet connection.
It also powers the GapGun, recharges the internal
battery and is a safe place to store the GapGun.
Standoffs are used in applications where the
parts being measured can’t possibly move. The
standoffs help stabilise the GapGun and position
it correctly.
The black V standoffs are for measuring gaps and
the grey H standoffs are for sealant beads.

Protect the GapGun by always using the Head
Jacket (above) and wrist loop.
Before each use: check lenses are clean, check
for any damage and verify calibration.
If the GapGun is dropped, check it for damage
and verify calibration.
The GapGun lenses need to be clean: Inspect the
highlighted areas for dust, grease or fingerprints;
clean them with the kit provided if required.
The GapGun Pro is designed for indoor use; keep
the system and its accessories dry and clean. Do
not use solvents on any surface.
Always verify calibration before use by measuring the Gauge Block or Pin Gauge supplied with your system. See
the Checking Head Calibration section in this manual for more details on running the Head Check checkplan.
FOV15/40/80 To perform a calibration check successfully, place the gauge block on a flat, stable surface.
Using the V-standoff, locate the tip in the gap to position the sensor at the correct distance
from the block.
FOV7 To perform a calibration check successfully. Using the V-standoff, locate the pin into the V
from the top of the standoff, taking care not to apply undue pressure to the pin.
NOTE: Failure to follow these steps may cause false calibration failures.

1. Tapping on the name of the Work Order displays five copies of the same checkplan, this number can be
changed in the Checkplan properties or globally in System options... under WorksOrderDefaultNumJobs .
2. The GapGun then prompts for a serial number which can be typed in, read by a barcode. The previous serial
number can be incremented or decremented using the +1 and –1 keys.
3. The Groups in the checkplan are then displayed showing how much of each Group has been measured.
4. Tapping on a Group displays the list of Features to be measured in that Group. Groups and Features can be
run in any order. However, the GapGun is configured to run through in the given order by pulling the trigger.
Note: Pressing and holding the up and down arrow keys automatically scrolls through the Groups and Features
lists.
The GapGun regularly searches for PCs running SPC3D when it is connected to a network. When it finds PCs
running SPC3D the Download… item appears.
1. Clicking Download… displays a list of the PCs running SPC3D.
2. To download a checkplan to the GapGun it must first be opened in SPC3D on the PC. Selecting a PC
displays a list of the checkplans that are open on that PC.
3. Selecting the checkplan downloads it to the GapGun where it becomes a Works Order.
4. The new Works Order is displayed on the Works Orders menu with the starred icon.

V7.6
Once all Features in all Groups have been measured the GapGun returns to the Groups menu. The percentage
shows how many Features were measured and the green and red bands quickly show how many were in and out
of tolerance.
The Summary describes these results in more detail. Returning from the Groups menu prompts the Operator to:
 Save & exit the Works order which saves the results so far but allows further Features to be measured.
 Lock & exit which locks the Works order in preparation to be returned to SPC3D.
 Lock & upload which locks the Works order and then prompts the Operator for a PC running SPC3D.
Once the upload is complete, the Works order can be deleted from the GapGun.
The features can be displayed in three formats, tapping the right and left arrows changes between the formats.
 List format shows Features in a text-only list. By default, the Actual measurement and Deviation from nominal
is shown, displayed in green if they are in tolerance and red if out of tolerance. Other details can be displayed
using the context menu (see below).
 Small Icon format shows Features with a small graphic to demonstrate how the measurement should be taken.
 Large Icon format shows a large graphic to demonstrate how the measurement should be made.
The large Icon formats also show a text instruction to guide the operator. This text is set using the “Instructions” item
on the card view in the workspace window.

V7.6 15
A Works Orders is normally deleted from the GapGun when it is completed and the results uploaded to SPC3D.
To delete it before this point requires Administrator Mode privileges, notice the Admin Icon in the top right
corner.
 The new menu item Delete works order is tapped and the list of Works orders currently loaded on the
GapGun is shown.
 Tapping the Works Order to be removed displays a prompt to confirm the action before deleting the
Works Order and any results associated with it.
Note: The Tools and Head check Works Orders should not normally be deleted.
Filters allows the Operator to only display subsets of Features such as all unmeasured features, all in-tolerance
features or all out-of-tolerance features.
Delete results allows the Operator to delete all the results measured so far in this Works order. If this is called
from the Groups or Features screens then the results from a single job only will be deleted. This allows wrongly
entered serial number to be corrected without losing all other results in this Works Order. If this is called from the
Jobs screen then ALL results associated with this Works Order will be deleted.
Delete works order allows the Administrator to delete the whole Works order from the GapGun.
Note: The Tools and the Head Check Works Orders should not normally be deleted.

16 © Third Dimension Confidential Document D13-1604-GGUSER-EN-3.4
V7.6
The calibration of the head can be checked by selecting the Head Check item at any time during measurement.
1. The Operator should then select the Group relevant to the head installed on the Gapgun.
2. Each of the features on the gauges should be tested using the up and down arrows.
3. Each measurement must be taken at least three times and the Cg and Cgk calculated. The check can be
restarted at any time by tapping Restart. Once enough successful measurements have been captured the
result is shown, in green if the calibration is okay and in red if it is out of calibration. The Operator should
seek advice on how to proceed from a Supervisor.
Columns allows the details displayed in the List format to be customized. These settings are changed for all
Works orders measured on this GapGun once set.
Selecting more columns decreases the number of Features that can be displayed on one screen so there is a trade
-off between showing Features and showing details. All the details are displayed in the Large Icon Feature display
and can be accessed by using the left and right arrow keys at a time.

V7.6 17
The GapGun can be turned on and off switch using the button below the trigger guard. The GapGun can also be
turned off by tapping the Power off option on the Context menu.
The battery icon indicates the charge remaining in the internal battery, an estimate of the remaining battery life is
displayed when the GapGun is running on its internal battery.
The battery will recharge from any external source such as a Docking station or a clip-on battery pack. It will
display a yellow flash to show that it is recharging.
The battery will not recharge if the internal temperature rises above 43°C, the temperature and a red cross are
displayed to shown when this condition occurs, charging recommences once the temperature drops below 43°C
again.
The Vchange sensors can be exchanged at any time in normal operation other than when in a measurement.
 The GapGun registers that the sensor has been removed;
 The GapGun registers that a new sensor has been mounted;
 The GapGun tries to load the calibration data for the new sensor. If a no calibration file is found, the GapGun
will search a mounted USB stick for the required file. The calibration file must be loaded before it can be used
for measurement.
If the calibration file has expired, a warning message is given and the option to continue or search for a newer
calibration file is offered. The GapGun will probably continue to measure accurately which can be checked by
performing a Head Check but is technically out of calibration.

18 © Third Dimension Confidential Document D13-1604-GGUSER-EN-3.4
V7.6
Many management and configuration options can only be performed by an Administrator.
 To access these functions the GapGun must first be put into Administrator Mode. Click on the context
menu icon and tap on the Administrator item.
 The password must be entered into the input screen. By default the password is set to 4321
 The Administrator Menu lists various management and configuration options to configure the GapGun as
required. Because the list is longer than one screen the up and down arrow keys can be used to scroll up
and down the screen.
Note: When the GapGun is in Administrator Mode a small green figure is shown in the top right corner.
GapGun Name Before V7.6 this is set to the serial number of the GapGun but can be changed as required. From
V7.6 onwards it is used as the network name of the GapGun. The handle operating system adheres to RFC-952
which means this name cannot start with a number so “3DSW-xxx” is illegal. It now defaults to “GapGun”.
Language The GapGun interface language can be set to any of the languages on this menu.
Note: Checkplans will be displayed in the language of the SPC3D used to create them.
Font Size The size of the text on the GapGun screen can be changed between Huge and Tiny.
Date/Time The Date and Time on the GapGun can be altered. However, the date and time are normally
synchronised with SPC3D whenever the GapGun connects to the PC. The time zone should be set to match that
set on the PC.

V7.6 19
The GapGun can operate in two modes; Roaming mode where GapGun does all its own processing and
Coprocessor mode where a PC running SPC3D does the calculations so that the GapGun can process the data
more quickly.
When using the GapGun MX+ and for some measurement Features such as the BSE family or complex multi-
curve fits when using the GapGun Pro, Coprocessor mode should be used to achieve acceptable speeds of
measurement.
To configure this mode:
 Select a particular SPC3D server from the list or
 Select Any so that any SPC3D server on the network may be used as coprocessor or
 Select None to disable coprocessor mode.
The selection of co-processor configuration has been moved
from the GapGun to each individual Checkplan. This means
that which ever GapGun the Checkplan is run, it will try to use
the same co-processor.
However, this means that Checkplans produced by SPC3D V7.5
or earlier are not compatible with GapGuns running V7.6 or
later.
The co-processor is configured in SPC3D on the Works order
Tab of the Checkplan Properties.
The IP address or hostname of the PC running the co-processor
is specified, the port on which the co-processor will
communicate is set, this is normally
port 21030. Ticking the Coprocessor
box will make the GapGun contact
the co-procerssor on the specified
port when it runs the Works order.
This dialog is also used to define
where add-ins such as Inline View
are being run.
Note: V7.6 and later versions of
Inline View can also operate as co-
processors removing the need to run
a separate copy of SPC3D.

To control the GapGun MX+ via CERDISP uses a slightly different method the the GapGun Pro.
On the PC the program to run is: C:\Program Files (x86)\Third Dimension\SPC3d7\Utils\CERHOSTGG4.EXE
 On the GapGunMX+, CERDISP requests the IP address of the PC on which CERHOSTGG4 is being run.
 The utility can then be hidden by tapping the Hide button. Tapping CERDISP again will display the dialog
to allow the utility to be closed down.
 On the PC a live image of the GapGun screen is displayed and this can be used to control the GapGun
interactively using the mouse and keyboard.
The GapGun can be accessed remotely from a Windows PC. Tap CERDISP on the Administrators Menu on the
GapGun.
To control a GapGun Pro, on the PC run: C:\Program Files (x86)\Third Dimension\SPC3d7\Utils\CERHOSTGG5.EXE
1. Run CERDISP from the Administrator Menu to advertise the GapGun on the network.
2. Run CERHOSTGG5, select File->Connect , select the target GapGun and click OK.
3. CERHOSTGG5 displays a live image of the GapGun screen. The GapGun can be used to controlled
