SAFETY NOTICES / 1

OPERATOR’S MANUAL

LIABILITY

DICKEY-john designed the GAC® 2500 to measure oilseed and grain moisture content. We rigorously test and calibrate each instrument before it leaves the factory. Use of the instrument in the field, however, is subj ect to environmental and operating conditions beyond our control. DICKEY-john

disclaims all liability for damages resulting from environmental and operating conditions beyond our control and for any damages that might follow incorrect results due to those environmental or operational conditions.

Therefore, we expect the operator to take responsibility to assure that the results of the testing is as accurate as possible by following approved maintenance procedures on a regular basis, by cleaning the instrument and its sensors on a regular and as-needed basis depending on the amount of dust, dirt, and debris encountered in the instrument’s use, by monitoring performance using daily check samples, and by adhering to the check procedures set forth in the manual. As with any kind of sophisticated equipment, optimal results depend in part on proper cleaning and maintenance.

For questions concerning these issues, refer to the product warranty, or call your DICKEY-john representative.

APPROXIMATE CALIBRATION READING

An approximate/not official reading, if set to metric, that displays on the Analysis screen might be the result of an old calibration installed on a new instrument; typically a custom calibration.

TIP: If an approximate reading is not expected, go to the Edit Product screen. If TW Metric Slope and TW Metric Bias do not appear on screen as a line item then the calibration is old. Or if TW Metric Bias value is 0 the calibration is old.

NOTE: A certified calibration on all

GAC 2500 models that has been altered from its original state and renamed will result in the test weight appearing as “approximate” on both lb/bu or kg/Hl readings.

Contact DICKEY-john Technical Support for assistance on how to update the calibration.

CLEANING THE TEMPERATURE SENSOR PROBE

IMPORTANT: Any particles in front of the sensor’s optics can affect

measurement performance. Therefore it is crucial to sufficiently clean the sensor. For excessive dust and/or foreign material buildup on or around the temperature sensor, it is recommended the instrument be returned to DICKEY-john Service or authorized service center.

The temperature sensor may require clea n ing due to du st bu ild up and/o r foreign material that has collected around the sensor that could potentially cause temperature error readings during analysis. Temperature sensor cleaning should be performed weekly or more often, as needed, based on surrounding environmental conditions. Factors such as dust, temperature extremes, grain dust, and external humidity vary from location to loca tion. It is important the temperature sensor is visually inspected and cleaned each time a regular maintenance check of the instrument is conducted. If there are any questions about the cleanliness or instrument performance, cont act your local authorized service center.

Tools required for cleaning the temperature sensor probe:

1. One of the below cotton swabs: – Standard 6” long cotton swab (i.e. McMaster-Carr p/n 7074T12) for

flush sensor

– 6” long, tapered tip cotton swab (i.e. McMaster-Carr p/n 71035T54)

for embedded sensor
