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.

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.
