BEFORE YOU BEGIN Button Functions ! READ BUTTON - Reads the Percent Moisture Content value (%MC), corrected for temperature and species. @ CALIBRATION CHECK BUTTON - Checks meter calibration. It also displays the average of up to 100 accumulated readings; displays the maximum stored reading; erases the readings. # SPECIES BUTTON - Sets the species code for the wood you are using. Species are numbered from 1 to 48 and are listed on the Species Code Chart.
SET SPECIES The J-2000 defaults to Species Code #1 - Douglas Fir - the USDA standard and basis for all calibrations. Because the electrical characteristics of different species vary, all species read differently at the same moisture content. For this reason you need to adjust for species. If you are working with a species other than Douglas Fir, set the species code using the species button , and the meter will make the necessary corrections. # # hTo change species press the species button .

SET TEMPERATURE The J-2000 defaults to a temperature of 70ºF. As wood temperature increases, its electrical resistance decreases and indicated moisture content rises. Lower wood temperatures result in lower indicated moisture content. A correction is necessary if the wood temperature is outside the range of 50ºF (10ºC) to 90ºF (32ºC). Set the temperature accordingly and the meter will make the correction. hTo change temperature press and release the temperature button .
SET PIN CALIBRATION The basic factory calibration of the J-2000 is for use with uninsulated pins – either the integral pins or with an optional external electrode, such as the #4-E. The difference in readings between insulated and uninsulated pins is small below 10% moisture content. The difference increases as moisture content increases above 10%. When using an electrode with insulated pins, such as the 26-ES, you can change the calibration to compensate for this difference.
INFORMATION ABOUT YOUR READINGS Readings below 6% will be displayed as a numeric value, (-##.#), and will not be added to accumulation. A reading below 6% which is due to temperature and species adjustments will be shown as a numeric value with no minus sign and this reading will be added to the accumulation. Readings above 40% are always displayed as 999 and are not added to the accumulation. The meter will accumulate up to 100 readings.
PIN TALK There are two types of contact pins - uninsulated, which were provided with your meter, and insulated. When using uninsulated pins, push them in to the wood to their full length, if possible. This will give you the highest measured reading. Insulated pins read only at the tip and can be driven to a desired depth to gather shell and core (gradient) information. Additional types and lengths of both the insulated and uninsulated pins are available for specific applications.
SERVICE FOR YOUR METER hBefore sending in your meter we recommend you give one of our trained technicians a call. Many times troubleshooting can be taken care of over the phone. Call us at 1-877-DELMHORST. hPack your meter securely. Enclose a purchase order or letter with a brief description of the problem. hThere is no need to call us for a return authorization number if you are within the U.S. Customers outside the U.S. must contact us for more specific instructions prior to returning a meter.
WARRANTY Delmhorst Instrument Co., referred to hereafter as Delmhorst, guarantees its J-2000 meter for one year from date of purchase and any optional electrodes against defects in material or workmanship for 90 days. If, within the warranty period, you find any defect in material or workmanship return the meter following the instructions in the Service for Your Meter section.
