Testing Procedures - TRAMEX CME 4 Manual De Instrucciones

Concrete Encounter CME4
Where covered floor slabs are being tested, all covering
materials, adhesive residue, curing compound, sealers, paints
etc., shall be removed to expose a test area of clean bare
concrete. For removal of any existing flooring or adhesives,
strictly observe all the appropriate safety and health practices
relevant to cleaning and removal of these types of materials.
Removal of covering materials and cleaning if required shall
take place a minimum of 48 hours prior to testing.
Use of water based cleaning methods that could lead to
elevated surface and/or sub-surface moisture levels in the
floor slab are not recommended, and testing after such
treatment could result in elevated readings.
No visible water in liquid form should be present on the
concrete at the time of testing with the CME 4.
Avoid testing in locations subject to direct sunlight or sources
of heat.
Use of artificial aids for accelerated drying of concrete is not
recommended. If they are being used it is recommended they
should be turned off at least four days before taking final
readings.

Testing procedures

1. Remove any dust or foreign matter from the Concrete
Encounter CME 4 electrodes before commencing tests.
Make sure that the floor slab being tested is clean and bare
and free from dust, dirt or standing water.
2. Push the ON/OFF button and press the instrument
directly onto the surface of the material being tested
ensuring that all of the electrode spring loaded pins are
fully compressed. Read the moisture measurement from
the appropriate scale of the moving coil meter dial.
3. On a rough surface, take a number of readings in close
proximity to one another. If the readings vary, always
use the one with the highest value.
