F.A.Q.

Is the PosiTest CMM calibrated at the factory

The PosiTest CMM arrives fully calibrated and ready to measure. A Test Certificate is included, which documents actual readings taken by your instrument at our calibration laboratory on concrete blocks with the moisture content determined gravimetrically (percentage of dry weight) as described in ASTM F2659.

Beware of Certificates or Certificates of Conformance offered by competitors. These typically do not include actual instrument readings, and are often insufficient to meet common quality requirements.

How often should the PosiTest CMM be recalibrated

PosiTest CMM Concrete Moisture Meters include a Test Certificate with no expiry or end date. They have no shelf life, therefore the length of time in the field is not a good indicator for recalibration intervals. Many organizations with quality programs and recertification programs require annual recalibrations, and this is a good starting point for most users. DeFelsko recommends that customers establish calibration intervals based upon their own experience and work environment. Based on our product knowledge, data, and customer feedback, a one year calibration interval from the date the instrument was placed in service is a good starting point.

How does the PosiTest CMM differ from the PosiTector CMM IS

The PosiTector CMM IS measures concrete moisture as described in the ASTM F2170 test Method. It involves drilling a hole into the concrete (generally 40% of the depth of the slab), and using an electronic relative humidity probe to quantitatively measure the moisture directly in the slab. It is a destructive test that requires at least 24 hours of being in-situ before an acceptable reading is taken.

The PosiTest CMM measures concrete moisture as described in the ASTM F2659 test method using a non-destructive electronic impedance meter to instantaneously measure comparative moisture content within the top of a concrete slab.

Why is concrete moisture measurement important

Before applying a protective coating or other flooring materials to a concrete slab, it is critical to ensure that the moisture level inside the concrete has decreased to acceptable levelstypically 75% Relative Humidity (RH), 3 lb/1000 ft2/24 hours MVER, or 5% Moisture Content (MC).

If not, moisture can accumulate below the coating or flooring causing discoloration, cupping, buckling, blistering, adhesive failure, and/or mold growth. There are various methods used for concrete moisture measurement. One common method to determine the moisture condition of a concrete slab uses a non-destructive electronic impedance meter, such as the PosiTest CMMas described in ASTM F2659.

How many readings can the PosiTest CMM store into memory

The PosiTest CMM is capable of storing up to 200 readings into memory. It features a USB port and includes a USB cable to download, view, and print stored readings quickly and easily with PosiSoft Desktop.

What information does the PosiTest CMM store into memory

The PosiTest CMM Concrete Moisture Meter stores each saved reading with the reading numberin all three available units (concrete 0-6%, carbide 0-4%, and relative).

What are the different measurement scales available for the PosiTest CMM

The PosiTest CMM features three different measurement scales:

  • Concrete 0 to 6%: This scale is calibrated using the gravimetric method (percent dry weight).
  • Carbide Method 0 to 4%: This scale is equivalent to the carbide method.
  • Relative 0 to 100: Used for taking readings for reference comparisons. This scale does not indicate moisture content or humidity.

What are the different measurement modes available for the PosiTest CMM

The PosiTest CMM features three different measurement modes:

  • Continuous Measurement Mode is the default mode and continuously updates the display with the current measurement value.
  • Hold Max Mode displays and holds the maximum reading until the memory button is pressed to save it, or the power button is pressed to discard it.
  • The innovative Hold Max and Save Mode waits for the reading to stabilize, then automatically saves it into memory.

How long do the batteries last in the PosiTest CMM

The PosiTest CMM uses two AAA batteries. Typically, operation life extends to 30 hoursideal for all day use.

How is the PosiTest CMM checked for accurate operation

The PosiTest CMM includes a Check Standard to verify the meters operation and accuracy. The PosiTest CMM is placed onto the Check Standard and the reading is checked against the range written on the standard.

Is reporting software available for the PosiTest CMM

Yes. The PosiTest CMMs readings can be downloaded, viewed, and printed quickly and easily with PosiSoft Desktop, a free download.

Fully customizable reports can be created to match existing paper forms or layouts. If other DeFelsko instruments such as the PosiTector CMM IS, PosiTector 200, or PosiTector DPM are used on the same job, measurement data can easily be compiled into one report.
