Glazier Test Tool
The View Glazier Test Tool (GTT) is a portable, convenient way to test the View IGU, IGU Smart Window
Connector, and cable operation. In a 30-60 second test, the GTT will indicate whether the windows, Smart
Window Connector, and cables are connected and operating properly. This device should be used on all
View installations as per the below instructions.
This device is designed for use by Glaziers, LVEs, and View FSEs who install and test View Smart Windows.
This guide is relevant only to the successful operation of the Glazier Test Tool. For information related to
glass returns, remediations, and testing documentation, please refer to the View Glazier Quick Start Guide.
Glaziers:
Testing upon receipt from View (required):
It is required that the glazier test the IGU’s upon receipt from View. These tests that are completed before
the IGU goes into the framing system do not need to utilize the grounding clip.
Testing of shop installed systems (required):
For shop built (unitized systems), it is required that glaziers test the cabling before the unitized frames are
sent to the job site.
Testing upon installation (required):
This is the critical test to ensure proper final installation and is required as per View Specifications. Once the
windows and any adjoining elements that could interfere with cabling have been installed, it is time to do
final testing of all IGU’s and record the results. The testing should be done on the IGU cable, which exits the
framing system for each IGU. This test should be completed for all framing types.
Low Voltage Electricians:
Testing on cabling exiting framing system (required):
It is required that the LVE test the IGU cable leaving the framing system before connecting to any further
IGU cable runs.
Cabling up to but not including the Window Controller (required):
The LVE must test on the cable up to where the window controller will be connected. Note that this cable
must be connected to the window in order for a valid test. Also, note that any cabling upstream of the
window controller cannot be tested with the GTT.
The included ground alligator clip should be used for all testing of in frame cabling both at glazing shops
(unitized) and on installed framing systems.

Turn on the GTT by holding down the center button for 3 seconds. The LED lights will turn on to indicate the
device is on. Ensure there is available battery charge by checking the battery indicator as shown below. If
the charge is low, charge the device using the included 12V DC Wall Charger. The GTT can take up to 8 hours
for a full charge.
Ensure battery is charged:
STOP: The glass must be clear
In order to have an accurate test result, the glass must be clear (free of charge). Please ensure that a
shorting cap is on the IGU Smart Window Connector. If there is no shorting cap, please connect one and wait
15 minutes before testing. This must be done for all windows.
Step 1: Connect GTT to IGU Cable or Smart Window Connector
In order to test, attach M8K connection on the GTT to the IGU cable or Smart Window Connector to be
tested.

Step 2: Attach the alligator clip to the window
frame or bonded metal if testing field cabling
Attach the alligator clip to a grounded metal part
(not anodized or painted) of the frame to create a
common ground (without this, the system will be
unable to test for ground shorts such as a screw
going through cable or bare wire touching the
frame). This is required for all testing where the
cabling is inside the frame (not required for IGU
receipt testing). If the frame does not have raw
metal to connect, connect to a screw going into the
frame. If there is a doubt whether there is continuity
between the frame and the alligator clip, complete
a continuity test between the alligator clip body
and the frame to be connected using a digital
multimeter.
Step 3: Ensure GTT is ready to test
The GTT can start testing once it reads the Smart Window Connector. This will be indicated by a slowly
flashing green light on the test status indicator. This should take less than 5 seconds. If the indicator does not
indicate the test is ready within 10 seconds, there is an issue with the cable and the test has failed.

If the test is passed for the final onsite installation, apply a green TESTED label (as provided by View) to the
IGU cable or Smart Window Connector and move on to the next test.
Step 4: Start test
Once the GTT indicates it is ready to test, press the test button to begin testing. The test can take up to 30
seconds to be completed. The LED indicator on the bottom of the device will go either solid red or solid
green to indicate either pass (green) or fail (red). Flashing lights indicate that the test is still underway.
The progress indicator lights indicate dierent states before, during and after testing. Consult the table
below for troubleshooting of dierent LED configurations of the progress indicators.
Cable Damage: Any cable damage will either lead to a failed completed test or failure to begin the test. If
the GTT is fully connected and the test won’t begin (flashing red light), this indicates either a damaged cable
or missing IGU parameters. Depending on which wire in the cable is damaged, the test may do a full test and
then fail or fail to start completely. Both should be considered failures.
Missing Smart Window Connector Parameters: If the IGU parameters are missing, the test will fail to start
and show double blinking light on large indicator light as per chart above.
Non tinting IGU: If an IGU is completely unable to tint and hold charge (i.e. Busbar disconnected), the test
will fail.
What types of failures does the GTT test for?
Tinting Performance: The GTT does not tint the glass. Slow tinting IGU’s are not tested as part of this test.
Visual Defects: The GTT does not tint the glass so visual defects will not be visible. Otherwise, working IGU’s
which have halos or other visual defects will pass the GTT test.

Q: The GTT is charging slowly. Is something wrong?
A: The GTT requires 8-10 hours for a full charge.
Q: How can I be sure the alligator clip is connected to the frame?
A: The best way to ensure a connection is to attach the clip to a raw (unpainted or anodized) part of the
frame after installation; in most framing system this could be any part of the frame but for coated system
like Hylar, the best alternative is a screw fastened into the framing system. The framing system does not
need to be earth grounded but rather the GTT needs to be grounded to the framing system. If doubt exists,
a multimeter can determine if the metal is grounded. In this case, with the grounding clip connected to the
frame, one lead should touch the ground clip and one should touch a similarly coated part of the frame. If
the continuity test passes, you are properly connected.
Q: I’ve received a high portion of failures in a particular area of the system. What’s wrong?
A: Please contact your View Project Manager (PM) for assistance with troubleshooting.
Q: I need more GTT’s. How can I order them?
A: Please reach out to your PM contact at View. The GTT can only be ordered as part of a complete kit.
