SETUP INSTRUCTIONS

INSTALL BATTERY

To open the battery/spare pins compartment, turn the meter over and use your
thumb to slide the compartment cover (Callout M of the figure) down and away
from the unit.

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 any default, follow the Advanced Setup Instructions beginning on p. 7.

MEASURING MOISTURE LEVELS

Surface moisture levels should be measured by the test pins if the surface
being tested can tolerate pinholes. If it cannot, use the meter's pinless sensor.
Internal moisture levels can be gauged by the pinless 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 P 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 the text "%WME" appears on the top line of the
LCD. Then press the test pins of the meter or the remote probe 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%.
