Operating Instructions; Measuring Moisture Levels - General MMD950 Manual Del Usuario

OPERATING INSTRUCTIONS

To power on the meter, press the
seconds. (To power off the meter, follow the same instruction.)
By factory default:
• The beeper is enabled, and beeps faster the higher the readout above
17%WME in pin measurement mode (17 in REL mode).
• The auto power off function is enabled, and activated by 3 minutes of
front-panel inactivity.
• The backlight is on.
• Manual calibration checking (see p. 9) is enabled.
To change the default settings for the beeper, backlight or auto power function,
follow the Advanced Setup Instructions beginning on p. 7.

MEASURING MOISTURE LEVELS

Surface moisture levels should be measured by the test pins of the remote
probe if the surface can tolerate pinholes. If it cannot, use the meter's spherical
sensor. Internal moisture levels can be gauged by the spherical sensor for
comparison purposes.
To use the remote probe, remove the small rubber yellow plug from the jack
on the right side of the meter (callout K of the figure). Then insert the white plug
at the end of the cable into the jack.
To make a surface moisture level measurement, press the Mode button as
many times as necessary until %WME appears on the top line of the LCD. Then
press the test pins against the target material. The material's surface moisture
level will be displayed as a percentage on both the LCD and the LED bar graph.
The bar graph uses LEDs of three different colors (green, yellow and red) to
indicate different moisture level ranges (low, medium and high, respectively).
Readings below 17% are considered low, readings between 17% and 30%
medium, and readings above 30% high. If the beeper is enabled with the
factory-default setting, it will beep faster the higher the moisture level rises
above 17%.
To gauge the internal or surface moisture level of a material, enter REL
mode by pressing the Mode button as many times as necessary until REL
appears on the top line of the LCD. To establish a baseline for relative readings,
