Protimeter MMS Moisture Measurement System

1.1 Switching the MMS ON and OFF

Prior to initial use, ensure that two 

AA

 batteries are correctly inserted in the 

battery compartment.

Note:

Low battery power is indicated by

 

 

on the display; when this 

symbol appears, replace the batteries.

Switch the MMS 

ON

 by pressing 

 momentarily.

The MMS switches 

OFF

 automatically after 1 minute, unless the default setup 

is changed (see section 2.5 for instructions). To switch the instrument 

OFF

 

immediately, press 

 and hold for at least 3 seconds. Once 

 has been 

depressed for 3 seconds or more, all text blocks appear on the display; when 

 is released, the text blocks disappear and the unit switches 

OFF

.

1.2 Optional Accessories

A range of optional accessories may be used with the Protimeter MMS. These 
include:

•

hammer electrodes

•

data download software & cable

•

additional Hygrosticks and Humisticks

For more information please contact GE Sensing.

2 Moisture Meter Modes

The Protimeter MMS can be used to detect and measure moisture in non-
conductive solid materials such as wood, drywall and masonry. Two modes of 
operation are available, the 

Search Mode

 for qualitative measurements and the 

Measure Mode

 for precise and localized moisture content measurements in 

wood or WME values in materials other than wood.
