I. GAGE CONFIGURATION
Section I is a one time setup. After a successful gage configuration is finished there should be no
need to repeat section I. It is recommended to store a copy of the gage files onto a personal
computer or laptop. Consult the collector manual or, if purchased, the TranSend manual for
further details.
Flush Setup
This configuration will produce a negative value for flush when the tip extends beyond the
nominal (master) point. To reverse the values enter -10 in step 10.
1. Press <menu> to turn on the collector.
2. Press ▼to highlight “Gage”.
3. Press <enter>.

It is recommended to assign simple user name to the gage files such as; flush, margin, etc. This
will help to identify different setups.
4. To assign the gage file name, press ▲or ▼to highlight “G2”* in the “Gage List” and press
<enter> on the collector.
*G2 has the ability to support “sub files”. These are files that allow multiple styles or
configurations of gages to be used by the same collector. To create sub files highlight G2 and press
►►, this will create a sub file of G2a. Each press of ►► creates another sub file. The balance of
this instruction will be based on G2
5. Use the ▲,►,◄, or ▼to highlight the first character of the new file name then press
<enter>, repeat the process until the gage file name is spelled. Then press ►► to accept the
new name.
6. Press the ►to “Configure”, by
default the screen may read as
follows.

7. The “Configure Gages” screen needs to be set as follows. Failure to set this screen properly
may cause undesired results.
8. If changes to this screen are needed, press ▲or ▼to highlight either “Type”, “Master Type”,
“Master With”, or “Zero Before Read” then press <enter> to toggle the different choices.
9. To make changes to the “Scale” or “Zero Master” press ▲or ▼to highlight “Scale” or “Zero
Master” and press <enter>. This will bring up the numeric keypad. Key in the new value and
press ►► to accept.
“Gage Port G2” must
be matched to “Master
with G3” to calibrate
both flush and gap at
the same time.
If the “Gage Port” is
set to “G2a” then the
“Master” needs to be
G3a

Gap Setup
This configuration will produce a negative value for flush when the tip extends beyond the
nominal (master) point. To reverse the values enter -10 in step 10.
11. To assign the gage file name, press ▲or ▼to highlight “G3”* in the “Gage List” and press
<enter> on the collector.
*G3 has the ability to support “sub files”. These are files that allow multiple styles of gages to be
used by the same collector. To create sub files highlight G2 and press ►►, this will create a sub
file of G3a. Each press of ►► creates another sub file. The balance of this instruction will be
based on G3
12. Use the ▲,►,◄, or ▼to highlight the first character of the new file name then press
<enter>, repeat the process until the gage file name is spelled. Then press ►► to accept the
