then quit. Measure again and adjust, until the measurements are satisfied. The calibration is subject to each range. Calibrate each range independently. The calibration results are stored in the instrument's memory, which is not lost after shutdown. Note: 1, To test the accompanying calibration specimen using proper measuring method, if the actual measurement exceeds ±10% of the calibration value of the specimen, calibrate using the calibration function by the actual error percentage with range less than ±20%. -

Page 17: Routine Maintenance And Care
5 Routine Maintenance and Care 5.1 Pickup 1) After measuring, put the pickup into the box in time; 2) Protect the stylus of the pickup; 3) The pickup is a key component to acquire the measurement signal, precise, sensitive and fragile. Handle carefully. -
Page 18: Height Stand
2. The height support must be locked reliably. 3. Do not adjust the stylus position using the height support during measuring. Adjust the adjustable feet to the desired height before measuring. Measure with calipers to meet the requirements. 7.2 Height stand Use a height stand to adjust the position between the instrument and the workpiece more accurately for more reliable and stable operation, to expand the measuring space and measure larger workpieces. -
