How to measure surface profile Ensure probe is 90° to substrate to ensure accurate readings and calibrate the gauge on a glass zero tile. To take one spot measurement, take either 5 or 10 readings within a 100mm (4”) diameter area. The measurement displayed is either the average peak-to-valley height or the maximum reading of the 5 or 10 readings, depending on which measurement mode you have selected. To establish the average surface profile of an area, record 5 spot measurements for each 1m x 1m (3ft x 3ft) area Elcometer 224 Accessory Part Numbers: T22420053 Replacement Probe Tips; Pack of 2 with Fixing Tool T22420095 Replacement Probe Tips; Pack of 5 T22419793 Probe Tip Protection Cap T22421882C Certified Calibration Test Kit: 125μm & 500μm (5 & 20mils) Calibration Foils, Glass Zero Tile & Calibration Certificate T22420072 Glass Zero Tile T99921325 USB Cable T99924797 USB Bluetooth Adaptor (V2.0 ) – for PC’s without Bluetooth T99922341 Self Adhesive Screen Protectors (x10) T22423371 Plastic Transit Case
