The operating instructions for the model BD-2100 are divided into two sections. Section A is a step-by-step guide to the different features and basic use of your moisture meter. Section B contains information on how the meter is used for testing different materials. Please read the instructions carefully. If you require additional information, please contact Delmhorst for assistance.
SET THE SCALE Set the scale for #1 Wood, #2 Plaster/Concrete reference scale, or #3 Gypsum. hTo change the scale, press the scale button #. The meter will display the current scale for one second. hTo scroll forward through the scales hold the scale button # while the current scale is displayed and scroll to the scale desired. hTo scroll backward through the scales, press and hold the set-point button $ within one second of pressing and releasing the scale button #.
INFORMATION ABOUT YOUR READINGS The meter will accumulate up to 100 readings. After all 100 readings are “stored” it will not add new readings until the memory has been cleared. It will also continue to display the average of all 100 readings as a reminder that the memory is full. hTo add a reading to the sum of all the previously stored readings, release the read button ! within 2 seconds.
SECTION B PRACTICAL APPLICATIONS TESTING WOOD hSet the scale to #1 Wood hAlign the contact pins ^ parallel to the grain and push them into the wood to their full penetration, if possible. hPress the read button !. The meter displays the %MC for two seconds. If the displayed reading is above the set-point value the setpoint buzzer will sound.
The following conditions may cause high moisture content in wood: hLeaky gutters and down spouts hLeaky pipes or condensation on cold water lines in attic or hollow walls hFaulty flashing around windows, doors and where porch and dormer roofs meet sidings hEnd-grain wood that is not sealed with paint at all joints around windows, corners, and butt joints hPorch columns that do not have good drainage and ventilation where they rest on porch floors hSiding or any other wood that is in contact with the ground
TESTING GYPSUM hSet the scale for #3 Gypsum (measures gypsum %MC over the range of 0.2% - 50%). hTo take a reading, push the contact pins ^ into the gypsum to their full penetration, if possible. hPress the read button !, and read the moisture content on the display. The meter displays the reading for 2 seconds. The set-point buzzer will sound if the displayed reading is above the set-point value. Also one of the LEDs on the front panel will light up as follows: Green - 0% to 0.
Testing Plaster Walls Under normal drying conditions and proper application of plaster (sufficient drying time between coats), surface readings give accurate results. However, if rapid drying occurs, the surface of the plaster may be dry, but moisture is still present below the surface and will eventually affect the paint or wallpaper. This condition occurs when there is high temperature or exceptionally good air circulation, or where brown scratch and white coats are applied within a few days.
Taking a Surface Reading: hDrive two hardened-steel masonry nails about 3/4” apart into the finish coat of concrete floor. Drive them about 1/8” deep so they make firm contact with the concrete and do not move when touched. hTouch the nails with the contact pins ^. ! hPress read button and read the reference scale. If the meter reads in the red or “wet” area, it shows the floor is not satisfactory for covering. If meter reads in the green or “dry” area, the surface is dry.
Key Factors to Consider: hThe age of the slab. National Wood Flooring Association guidelines specify to wait at least 30 days after the slab is laid before checking moisture content.
Key Areas to Check: hThe rear side of brick parapet walls — generally are not waterproof above the flashing line and frequently absorb moisture during rains. hPainted concrete floors on ground — subject to peeling as they absorb moisture from the earth, unless an effective vapor barrier has been installed. Tests on these materials should be made a day or so after they have been exposed to rain or other high moisture conditions to verify to what extent they absorb moisture.
Procedure: hDrill two 3/16” diameter holes, one inch apart through the siding. hUsing the #21-E, insert the #608 contact pins into the holes so that you make contact with the insulation. ! hPress the read button and take a reading. Take readings at various depths of penetration to determine the location of moisture. hFill holes with putty at the conclusion of the test. Meters are not calibrated to read the percentage of moisture content in the insulation.
