The PosiTest CMM Concrete Moisture Meter uses the principle
of electrical impedance specifically calibrated for comparative
moisture measurements of concrete.
Accurate and simple to operate, the nondestructive PosiTest
CMM records up to 200 measurements for download to a
computer with the included USB cable.
Before measuring with the PosiTest CMM, ensure that the
concrete surface is bare (uncoated), and free of dirt, dust, or
standing water. Inspect the spring-loaded sensor pins on the
underside of the gage and remove any dust or debris.
1. Press
to power up the Meter.
2. Verify operation using the included Check Standard (see
instructions on Check Standard).
3. Press
to select the desired measurement scale (pg. 3).
4. Press
to select between the 3 operating modes (pg. 3).
5. Place the Meter onto the concrete surface and press down to
fully compress the sensor pins. The sensor pins are designed
to measure accurately on smooth, rough, or uneven concrete
surfaces.
NOTE:
It is suggested that the Meter operator take 3 - 4
measurements in close proximity to one another, noting the
maximum measurement value for that inspection area. Using
the Hold Max mode (pg. 3) makes this process rapid and
convenient.
