4. MEASURING PROCEDURE 4-1 Pay attentions for the measurement 1)When make the fruit hardness testing, it always use compression function. Remark : The meter can use the " Tension " measurement, the display will show the '" - " mark automatically. However for the fruit hardness measurement is not use this function typically. - Page 8 3)Rotate the Sensing Head is prohibited. Some certain angles between Sensing Head & measuring object are not allowed ( ref. Fig. 3 ). Fig. 3 4-2 Normal Measurement 1)Slide the " Power Off/On/Peak Hold Switch " ( 3-8, Fig. 1 ) to the "...
- Page 9 * There are two kind sampling time of display, FAST and SLOW. Push the " FAST/SLOW Button " once ( 3-4, Fig. 1 ), if the upper left corner of LCD show " FAST " ( Fast Indicator, 3-3, Fig. 1 ), then the display reading is under the operation of fast sampling time.
