Page 6: First Step: Check And Change Settings For Pin And Pinless
First Step : Check and Change Settings for Pin / Pinless Mode Before using the Ligno-VersaTec, the active (previously chosen) settings in the meter need to be checked and if necessary changed to fit the job to be done. To recall active settings, press the SET/HOLD key repeatedly. -
Page 7: Pin Technology And Settings
Pin Mode Pin Technology and Settings The Ligno-VersaTec functions as a resistance-type meter in pin mode. The conductivity between the pins is measured and the moisture content is calculated according to the active wood species and wood temperature settings. The meter indicates the highest moisture value within the small measuring area between the tip of the teflonized pins. -
Page 8: Measurements
Pin Mode Measurements After settings have been checked and changed, press the READ key to obtain readings. The active settings appear briefly. Then, if no electrode is connected or if the electrode is not inserted into any material, the lowest possible reading for the active material and temperature settings appears. -

Pin Mode Pin Mode Pin Mode The ability to measure a moisture gradient up to 2” deep is one important reason why customers still use pin electrodes. In pinless mode you can measure only up to 3/4” deep. If high moisture levels are suspected deeper down, the only option to measure deeper than 3/4”... -
Page 10: Monitoring Using The Ligno-Versatec
An RH in-situ probe test and/or a Calcium-Chloride test is recommended by most wood floor manufacturers. See Page 21 for RH in-situ probe test in concrete with the Ligno-VersaTec. Monitoring using the Ligno-VersaTec Extension cables and probes can be installed to monitor remote areas, which are otherwise unreachable. -

For example: Elevate one end of the test board to create an air space underneath the board. If this is not possible, make sure the Ligno-VersaTec is set for the correct measuring depth. Measuring veneer, page 15. -
Page 13: Dual-Depth 1/4" And 3/4
When floor planks 5/8” thick are installed and measured with a pinless meter set for a 3/4” measuring depth, you cannot be sure that the subfloor or concrete underneath is not affecting the readings. With the Ligno-VersaTec on the 1/4” depth setting, you definitely only measure the floor planks . -
Page 14: Pinless Mode
This is the best way to compare surface and core moisture with the pinless measuring technology. Use the Ligno-VersaTec with a pin electrode to measure a moisture gradient in thicker wood. Measuring Wood: Check/change wood species setting: Code numbers 111-230. -

3/4” thick. Make sure that the selected measuring depth is 1/4”, when using code numbers 11-24. Also available in Ligno-DuoTec BW and SDM. The values indicated by the Ligno-VersaTec are WME percentages. WME is the wood moisture equivalent. The following example shows what WME means: If bamboo is acclimated to ambient conditions of 42%, the Ligno-VersaTec on the correct bamboo setting indicates 8%. -

1/4” measuring depth gives true moisture percentages, without includ- ing any material behind the sheetrock. Since the maximum measuring depth of the Ligno-VersaTec in scan mode is limited to 3/4”, it may be more conclusive to investigate moisture problems with the electrode... -

Pin and pinless, ASTM F2659, quantitative versus qualitative. In-situ RH testing: Use the RH mode of the Ligno-VersaTec with the RH BluePeg probes, and measure the relative humidity and temperature inside a hole in the con- crete. -
Page 22: Check Software Version
Why the RH test gives the most reliable results: Moisture distribution within an open concrete slab is often not uniform, especially when the slab has not dried completely or when the slab is on grade. The surface shows low moisture levels, whereas higher moisture levels are found in the middle of the slab or towards the bottom (espe- cially for slabs on grade). -
Page 23: Function And Calibration Check For Pin - Pinless - Rh
Function and Calibration Check for Pin and Pinless Mode All pin and pinless meters from Lignomat including the Ligno-VersaTec are built with high quality components, micro-processor based, to guarantee stable calibrations for many years of usage. All meters from Lignomat internally check and if necessary adjust the calibration before each reading. - Page 24 Step 3: Lignomat offers an external calibration check block TP. The block is used to confirm the calibration of all Lignomat pin meters. Connect meter, cable and electrode. Set the meter to pin mode. Select code # 103 and a wood temperature of 70 F.
