Calibration Calibration parameters are logically divided into groups of two parameters each – initial scale value and final scale value. value. A calibration check is provided after entering the values of each group. A calibration calibration check check can be initiated initiated without making m aking an entry: press the FUNC key key to advance to the desired calibration check. The lower display will show the parameter code (t., (t., rJ., etc.) and the upper display will show “on” or “off.” Press the s or t key to select on or off. To go to the next parameter without modifying the calibration, press the FUNC key when the displays shows “ off.” To return the previous parameter without modifying the calibration, press the MAN key. To set the t he parameter calibration, calib ration, pre p ress ss the FUNC key when the display shows “on.” The display will blank, and only the decimal point p oint of the t he LSD LSD of the lower display will be lit during the calibration step.
