Shure Electronic Accessory BLD5760 User Manual

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 0-
1000 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.

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   for 3 seconds, until the word “

nuL” 

appears in the display.

3. Release  ;

 

nuL” will flash for a few seconds and then disappear from 

the screen. The Aquant is now zeroed.
