Delmhorst F-2000T User Manual

OWNERS MANUAL FOR F-2000T
(VERSION 4.2 FOR BURLEY TOBACCO)
This addendum is to be used in conjunction with the Owners Manual for the F-2000 Hay Moisture Meter (attached). This addendum contains information specific to the tobacco applications. We recommend the user read the Owner’s Manual and addendum completely,
before using the F-2000T.
Whenever the battery is removed and then reconnected (i.e when power is applied), the meter will display the software version number (4.2) for one second and then shut off if no key is pressed.
The meter has FOUR keys - the “READ” key, the “CHECK” key, the “SET” key and the “TEMP” key (see the attached diagram).
1. TO RESET THE METER
Resetting the meter will restore the default settings and erase all the stored readings.
Press the “CHECK” key immediately, followed by the “SET” key. The meter will display “200” for two seconds and then shut off.
2. TO CHANGE THE SET POINT VALUE
The default set point value for the meter is 20.0%. The user can change the value between 8.0 and 37.0.
Press the “SET” key. The meter will display the current set point value. To increase the set point, keep the “SET” key pressed. The value will increase in steps of 1.0. To decrease the value, press the “TEMP” key within two seconds after pressing the “SET” key. The value will decrease in steps of 1.0.
3. TO CHANGE THE TEMPERATURE SETTING
The meter will automatically correct the moisture reading for sample temperature, provided the user has entered the correct SAMPLE TEMPERATURE in the meter. The user can set the temperature between 0º and 255º F.
The default temperature setting is 80º F. The meter will correct the moisture value by
0.05% for every degree change in the sample temperature.

Press the “TEMP” key. The meter will display the current temperature setting. To increase the setting, keep the “TEMP” key pressed. The temperature value will increase in steps of 5º. To decrease the value, press the “SET” key within two seconds after pressing the “TEMP” key. The value will decrease in steps of 5.0.
4. READING THE %MC VALUE
Press the “READ” key. Within 1 or 2 seconds, the meter will display the %MC between 8.0 and 37.0. The meter will automatically correct the reading for the sample temperature. The reading will be displayed for 2 seconds and if the “READ” key is still pressed, then the cycle will be repeated. The buzzer will sound if the displayed reading is above the set point value entered in the meter (default is 20.0).
The meter will “store” the reading, provided that the user releases the “READ” key, otherwise the meter will initiate another “READ” cycle without “storing” the previous reading. This feature lets the user take a number of readings in sequence and only “keep” the readings of his choice.
When the “READ” key is released, the meter will add the last displayed value to the sum of the previous readings (up to 100), provided the value is within the range. When all the 100 readings are taken, the meter will automatically display their average before turning off. No new value will be added to the sum unless the user erases the readings.
NOTE: The reading below 8.0% will be displayed as “.0” and above 37.0% as “99.9”. These are not considered valid readings and will not be stored.
5. CHECKING THE AVERAGE AND MAXIMUM VALUE OF THE ACCUMLATED READINGS (And erasing them)
As mentioned before, the meter adds the value of the new reading (provided that the “READ” key is released) to the sum of the previous readings. The meter holds this sum, as well as the number of readings added so far and the HIGHEST reading. Up to 100 readings can be accumulated. After that, the meter will stop adding the new reading and display the average every time a new reading is taken to remind the user to erase the readings to start accumulating the new ones.
At any time, the user can check the AVERAGE of the accumulated readings by pressing the “CHECK” key. The meter will display the number of readings accumulated for one second, followed by the AVERAGE value (displayed as “A xx.x”) for two seconds and the MAXIMUM value for another two seconds. If at the end of the total period, the meter finds the “CHECK” key pressed, it will erase the
2
accumulated readings. Hence, the user must release the key before four seconds if he wants to retain the readings. However, if all 100 readings are accumulated, then he should keep the key pressed to erase the readings so that the meter can accumulate the new ones.
6. TO CHECK THE METER CALIBRATION
To check the meter calibration, the user must PRESS first the “READ” key, immediately followed (within one second) by the “CHECK” key. The meter should display “12.0” +/- 0.2. Since a relay disconnects the external input when checking calibration, there is no need to disconnect the external electrode.
