Wall mounting the calibration station:
If wall mounting calibration station, hold unit
complete with backplate in required location on
wall then, using backplate as a template, mark
(4) hole positions on wall. Use (4) suitable screws
(and rawlplugs if positioning the unit on a brick
wall) to secure. The calibration station backplate
can be removed, if required, to mark hole
positions more accurately. Refer also to paragraph
3 below: permanent power cable connection.
Calibration station power supply
67109(Q):
There are three methods of providing power
to the GT series calibration station 67109(Q).
1. Via a 12V PSU (GMI Part No. 12444)
located in a socket on the top face of
the calibration station. Refer to Fig. 2.
2. Via a 12V vehicle power supply (GMI Part
No. 12988) also located in a socket on the top
face of the calibration station. Refer to Fig. 2.
3. Via permanent 12V power supply cable.
This requires removal of backplate before
wall mounting the unit, procedure as follows:
a) Remove (6) screws that attach backplate to the
calibration station.
b) Remove blanking plug from underside of unit.
c) Fit 20mm. ( 3 /
4
in.) cable gland - size to suit cable.
Note max. wire cross section area = 2.5mm2
d) Connect permanent 12V power supply cable to
J25 connector on calibration station PCB. (observe
correct polarity). Refer to Fig. 3.
e) Replace backplate then secure using (6) screws.
Calibration station power supply 67611(Q):
The GT series calibration station 67611(Q) is powered
via 12V power supply cable from PC Controller
unit. The PC Controller unit is powered via mains
cable (both cables are supplied with the unit).
1. The 12V power supply cable from PC controller is
located in a socket on the top face of the calibration
Fig. 2 12V Power Socket - Top station. Refer to Fig. 2.

Calibration Station
Calibration Station Gas Supply:
The gases can be plumbed in by using nylon tubing and
connect these to swage connector gas inlets at the top of
the calibration station. Outer diameter is 6mm. ( 1 /
4
in.).
1. Air 5. H2S (if applicable)
2. PPM 6. - Empty -
3. LEL 7. - Empty -
4. CO (if applicable) 8. Vol. Gas
Swagelok connectors must be finger tightened then,
using two spanners, tighten a further 11 /
4
turns. Do
not overtighten.
A gas pressure of 590 to 690 mBar (8.5 to 10 PSI)
should be provided to these gas inlets.
Calibration station computer connection and driver software:
* The calibration station has a USB connector that can be easily connected to a free USB port on the
computer. (*not applicable to 67611 and 67611Q)
Install the software from the enclosed CD-ROM to initially set up the gases.
Start the software. The first time you will be asked to select the com-port.
Install instrument in the Calibration Station
Make sure that the power contacts, on the back of the GT instrument and on the calibration station (shown
in Fig. 4), are clean and free of dirt / grease. As detailed on calibration station instructions label, carefully
position the GT in its docking location, as shown in Fig.1, with the bottom part first, placing the extension
pole recess at the bottom of the GT so that it docks with the holding clip shown in Fig. 4. Push the instrument
backwards so that it is located between the two holding arms then engage the securing strap. Locate the
probe as shown in Fig. 1.
Follow the further instructions on the front of the calibration station.
