BEFORE YOU BEGIN Key Functions ! READ KEY - Press to read the %MC. @ CALIBRATION CHECK KEY - This key, (when pressed with the read key) checks the meter calibration. It also displays the number of readings in memory (up to 100), the average, and the highest stored reading. It also clears the memory. # SPECIES KEY - Press to select the species code for the wood you are testing. Species are numbered from 1 to 48 and are listed on the Species Code Chart on page 5.
When the battery is removed and then reconnected, the meter displays its software version for one second and then turns itself off. After replacing the battery, you must reset the meter as described in Resetting the Meter section. A hard Reset is required if, after changing the battery, the display is frozen. This is sometimes caused by the interruption of contact between the battery and battery lead wire. Resolve this as follows: Disconnect the battery. Press and hold the Read key for 15 seconds.
hTo scroll forward through the species list hold the species key while the current species code is displayed and scroll to the species number desired. # hTo scroll backward through the species list, press and release the species key . Within one second, press and hold the temperature key . Continue to hold the temperature button and the species number will decrease. # $ $ hWhen scrolling in either direction, release the key to stop at your desired species.
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 key .
SET PIN CALIBRATION The basic factory calibration of the J-2000 is for use with non-insulated pins. Insulated pins read lower than non-insulated ones. The difference is small below 10% MC but increases as the moisture content increases above 10%. When using an electrode with insulated pins, such as the 26ES hammer electrode, you can change the calibration to compensate for this difference. hTo change the pin setting, press and release the species key , then press the calibration check key within one second.
INFORMATION ABOUT YOUR READINGS Readings below 6% will be displayed as a numeric value, (-##.#), but will not be added to the accumulated readings in memory. Readings below 6% due to temperature and species adjustments will be shown as a numeric value with no minus sign. These readings will be added to the accumulated total in memory and included in the statistical calculations. Readings above 40% are always displayed as 999 and are not added to the memory. The meter will accumulate up to 100 readings.
CARE OF YOUR METER To keep your meter in good working order: hStore your meter in a clean, dry place. The protective carrying case provided is an ideal storage place when the meter is not in use. hChange the 9-Volt battery as needed. Use only EverReady or Duracell brand batteries. Continued use with a low battery may cause the meter to go out of calibration. hChange contact pins as needed. Keep contact pins hand tightened. hClean the meter and contact pins with any biodegradable cleaner.
