The ETEKT+ RED/FAR and GREEN/CLEAR lights are optimized for single pane or IG
windowassembliesmanufacturedwith3/32"(2.5mm)or1/8"(3mm)glasswithanair
space between 1/4" and ½". Whenever you are operating on glass or air spaces
BEYOND this range, DISREGARD the and indicators--they have NO
meaning.
Therefore to fully test an IG unit when the thickness is not known, you must take a
reading from both sides of the window, measuring each piece of glass
individually. Watch ONLY for the NEAR/YELLOW indicator. If you do not obtain a
NEAR indication on either side of the IG unit, it is a CLEAR IG assembly. If you do
obtain a NEAR indication on one side of the window, that piece of glass contains
the low e, and it is on the second surface of the glass as explained on the
previous page.

The AE1601 is equipped with a low battery indicator that will indicate when it is
necessarytoreplacethebattery. Thelowbatteryconditionisindicatedbyblinking
the LED that gives the results of the test. Typically the LED result is shown in a
“constant-on” style. However when the battery needs replaced, the LED result will
be blinked. This is the warning indication that a new battery should be installed
sometime soon. The instrument will continue to operate correctly for a given time
after the warning is indicated. It is recommended that you replace the battery
soon. Once the battery voltage drops to a dangerously low level, the instrument
will NOT operate and the LED indicators will go into a continuous blinking pattern,
NOTallowingyoutousethemeter.
TheAE1601ispowered by a 9 volt alkaline battery. Please replace the battery with
analkalinebatterywhennecessary.
The AE1601 instrument will only detect the nearest low e coating it encounters.
Therefore if you have a window with more than one low e coating, the AE1601 will
only show the presence of the coating that is closest to the meter. If you believe
thereis morethanone coating,youwill needtotest theotherside ofthe windowto
confirm this. Remember, the instrument will only identify the nearest coating it
encounters. For triple pane applications, it is necessary to test both sides of the
window.
The AE1601 instrument can be used to identify ANY conductive coatings, even if
they are not low e coatings. Other known applications for the AE1601 include
identifying non-ceramic window films and also Pilkington’s “Optiview” anti-
reflectivecoating. Inmostcasesthe ETEKT+is ableto identifyother coatingsevenif

3. If the YELLOW/NEAR indicator lights on one of the sides of the window,
then that pane of glass contains the LOW-E coating.
4. Totally disregard the FAR and CLEAR indicators, as they are not valid in
this application.
5. The "CONTACTING" coating indication is valid for ALL applications,
regardless of thickness or air space.

Red Indicator
The RED light indicates that a
LOW-E coating exists on a FAR
surface of the window. The far
surfaces of the window are
surface #3 or #4 as you look at
the window.
The YELLOW light indicates that
a LOW-E coating exists on the
NEAR surface of the window.
The near surface of the window
is surface #2 as you look at the
window.
The GREEN light indicates that the
window is CLEAR of any LOW-E
COATING. NO LOW-E coating
exists on any of the surfaces
When the ETEKT+ is in direct
contact with a LOW-E coating
the GREEN, YELLOW and RED
indicators will all be lighted.
