GE GE Protimeter Aquant
Sensing User Instructions
Introduction
The GE Protimeter Aquant BLD5760 moisture detector is used to
assess and monitor the relative moisture level of non-conductive
and porous materials: such as plaster, masonry, concrete and
fiberglass (GRP). It is an ideal instrument for making rapid surveys
of solid walls and floors and to pinpoint areas of concern in tiled
shower cubicles, GRP boat hulls, motor homes and caravans etc.
The Aquant BLD5760 has a digital display that is synchronized
with a color coded LED scale. The digital display shows the relative
moisture level of the material under investigation on a scale of 01000 and the LED scale indicates moisture condition of the material.
The color-coded zones signify the moisture condition of the material under investigation. The green,
yellow, and red color-coded zones indicate the following:
• Material in the green zone is in a safe air-dry condition.
• In the yellow zone moisture levels are higher than normal but not critical; further investigation is
recommended.
• The red zone represents excessive moisture levels. If sustained, red zone moisture levels will lead
to decay in organic materials.

1Operation
The Aquant BLD5760 moisture detector has a radio frequency transceiver located in the bulge on it’s
underside to give relative readings within the material against which it is held up to a nominal depth of
3/4 in. (19 mm). The depth of measurement is subject to the characteristics of the material under test.
To use the Aquant, do the following:
1. Hold the Aquant away from surfaces as shown and switch ON by pressing
momentarily. The instrument may now be used to take measurements
or zeroed as appropriate.
2. Zero the instrument (with respect to the environment in which it is about to
be used) by pressing and holding
appears in the display.
3. Release
the screen. The Aquant is now zeroed.
; “nuL” will flash for a few seconds and then disappear from
for 3 seconds, until the word “nuL”

4. Place the instrument against the surface of the wall, floor or element at the
chosen point of measurement as shown. Ensure that your forefinger and
thumb do not extend beyond the top of the black plastic grip band and wrap
all fingers around the side of the instrument.
Note: The Aquant should be held at a nominal 25° to the surface so that both
top edge of the instrument and the sensor bulge are in contact with the
surface.
5. Read the relative moisture level value from the display and note that
moisture condition of the material from the color coded LED scale.
2 Zero Feature
The zeroing feature enables the user to compensate for the effects of changes in temperature on the
calibration. It is necessary to zero the Aquant if the following appear on the display when the
instrument is held in air away from surfaces:
• numbers, or
• three lines “---” and symbols “°C°F REL)))”are flashing
The recommended best practice is to always zero the Aquant with respect to the environment in which
it is about to be used, even if the display shows “0”. Read the Operation section above for details.
3 Hold Feature
The relative value shown on the display may be held for 3 seconds by pressing while the Aquant is
being held against a surface. This feature is useful when using the instrument in areas where the
display cannot be clearly seen.
4 Auto Switch-Off Override Feature
Press and hold for 3 seconds to switch the instrument OFF.
5User Set-Up Options
The Aquant is initially set-up to switch OFF automatically after 1 minute and to emit an audible
beep for readings beyond the yellow zone. The user may change these default settings by entering
the Set-up mode.
Setup the User Options as follows:
1. With the instrument switched OFF, press and hold the lower button
upper button . The display will show the firmware version number (e.g. “4.06”) until both
buttons are released.

6Error Messages
When zeroing if the error message E32 appears on the instrument display, signifying that the
instrument reading is beyond the zeroing range of 130.
7 Care and Maintenance
When the Aquant is not being used, then do the following:
• Store the Aquant in the carry case (provided with the kit) in a stable and dry environment.
• Remove the battery, if the Aquant will not be used for extended period of time.
• Replace the battery when the low battery symbol appears on the display.
The information contained in this leaflet is given in good faith. As the method of use of the
instrument (and its accessories) and the interpretation of the readings are beyond the control of
the manufacturers, they cannot accept responsibility for any loss, consequential or otherwise,
resulting from its use.
