  12. The Probe Range

  13. Probe Range Elcometer surface profile probes are fitted with a tungsten carbide user replaceable tip as standard, suitable for up to 20,000 readings. Probes have a measurement range of 0 - 500µm (0 – 20mils) and are accurate to ±5% or ±5μm (±0.2mil). Elcometer 224 Separate Gauges and Probes are ideal for measuring in awkward or confined spaces. Index

  14. Probe Range Elcometer 224 Separate Probes are available with a standard cable or armoured, reinforced heavy duty cable. The armoured cable is ideal for measuring in harsh environments and offers added protection against snagging and impact damage. Each probe is supplied with calibration test foils, probe protection cap and test certificate. Standard Probe Armoured Probe Index

  15. Calibrating the GaugeVerifying the Gauge Calibrationand Accuracy

  16. Calibrating the Gauge Calibrating the gauge is the process of zeroing on a smooth glass “zero” tile. The new Elcometer 224 has on screen instructions to guide the user through the calibration process. After continued use, the surface of the glass “zero” tile will begin to wear. If a repeatable zero cannot be obtained the tile should be replaced. Index

  17. Calibrating the Gauge If no zero tile is available, the “Factory Calibration” option can be used. This returns the gauge to the calibration set up during manufacture and test using reference probes but is not as accurate as a gauge calibration. Index

  18. Verifying the Gauge Calibration & Accuracy The calibration and accuracy of the gauge can be verified at any time using foils and a glass zero tile - without affecting any statistics or batch memory. Simply select “Test Calibration”, follow the on screen instructions and compare the reading value displayed with the glass “zero” or measured foil value. After continued use, the surface of the glass “zero” tile will begin to wear. If a repeatable zero cannot be obtained the tile should be replaced. Index

  19. Verifying the Gauge Calibration & Accuracy The Elcometer 224 precision manufacturedprobe tip will wear over time from a sharppoint to a flattened or rounded point.   This reduces the accuracy of the gauge as the tip cannot reach the trough of the profile. Tip wear and gauge performance can also be assessed by using the “Test Calibration” function. Index

  20. Probe Tip Replacement The Elcometer 224 probe tip is a consumable item with can be replacedby the user.   A 2-point factory recalibration is required after a tip replacement to ensure the continued accuracy of the gauge. Index

  21. Comparing the Elcometer 224’s

  22. Comparing the Elcometer 224’s The new Elcometer 224 follows the same menu structure as the Elcometer 456 Coating Thickness Gauge with “Cal”, “Batch”, “Stats” and “Menu” softkeys. The new Elcometer 224 significantly improves the product features of the existing gauge and has many of the new Elcometer 456 features. Index

  23. Comparing the Elcometer 224’s Features in the new Elcometer 224 not in the old model include: Additional Statistical functions: • Coefficient of Variation • High & Low Limits • Number Above and Below Limits Index

  24. Limits The Elcometer 224 can have user defined Upper and Lower limits for each batch. If a reading is outside set limits; • the red LED illuminates; • the alarm sounds; • the display reading turns red; • the relevant limit icon goes red When limits are set; the gauge also displays the number of readings that are above or below the pre-defined limits. Lower Limit Set Lower Limit Warning Upper Limit Set Upper Limit Warning Upper & Lower Upper Limit Lower Limit Limit Set Warning Warning n No. of Readings No. of Readings Below Limit Above Limit n Index

  25. Comparing the Elcometer 224’s Features in the new Elcometer 224 not in the old model include: Additional functions: • Counted Average • Live Reading (Trend) Graph* • Batch Review Graph • Fixed Batch Size • Alpha-Numeric Batch Names • Clear Batch Readings • Date and Time Stamp * The Live Reading (Trend) Graph is only available in Batch Mode. Index

  26. Counted Average Mode When using Testex® Tape, the replica tape measures the surface profile over a 70.89mm² area – the area of the memory foam. It measures the maximum peak-to-valley height within the test area. In order to establish the surface profile using an Elcometer 224, a number of readings over an area are required to generate an average profile. The average of the individual readings provides the user with the average peak-to-valley height over the measurement area. Index

  27. Counted Average Mode The “Counted Average” feature on the new Elcometer 224 is a very useful technique for assessing an area of profile. To establish the average surface profile, between 5 and 10 readings should be taken within a 150 x 150mm (6 x 6”) area. The average of these individual spot measurements provides the user with the peak-to-valley height over the measurement area. The Counted Average mode allows the average of the spot readings to be recorded into memory automatically. Index

  28. Graphs The new Elcometer 224 gauges have two “graph” functions: Live Reading (Trend) Graph The user can view a line trend graph of the last 20 measurements, which is updated automatically when each reading is taken. Index

  29. Graphs The new Elcometer 224 gauges have two “graph” functions: Live Reading (Trend) Graph The user can view a line trend graph of the last 20 measurements, which is updated automatically when each reading is taken. Up to five horizontal axis are displayed representing different values / statistics as follows: • - Highest reading in the batch • - Lowest reading in the batch • - Mean of readings in the batch • - High limit for the batch • - Low limit for the batch Index

  30. Graphs The new Elcometer 224 gauges have two “graph” functions: Live Reading (Trend) Graph The user can view a line trend graph of the last 20 measurements, which is updated automatically when each reading is taken. The readings are displayed as white or red vertical bars: • - White if a readings is within set limits(or no limits have been set) • - Red if outside set limits Index

  31. Graphs The new Elcometer 224 gauges have two “graph” functions: Batch Readings Graph The user can review all readings in a selected batch as a graph. Index

  32. Graphs The new Elcometer 224 gauges have two “graph” functions: Batch Readings Graph The user can review all readings in a selected batch as a graph. Up to five horizontal axis are displayed representing different values / statistics as follows: • - Highest reading in the batch • - Lowest reading in the batch • - Mean of readings in the batch • - High limit for the batch • - Low limit for the batch Index

  33. Graphs The new Elcometer 224 gauges have two “graph” functions: Batch Readings Graph The user can review all readings in a selected batch as a graph. The readings are displayed as white or red vertical bars: • - White if a reading is within set limits(or no limits have been set) • - Red if outside set limits Index

  34. Graphs The new Elcometer 224 gauges have two “graph” functions: Batch Readings Graph The user can review all readings in a selected batch as a graph. If there are more readings in the batch than can be displayed on a single screen, multiple readings will be combined into one bar. Should a single reading within the ‘combined bar’ be outside theenabled limits, the whole bar will be red. Pressing the Zoom+ softkey allows each individual reading to bedisplayed thereby showing the individual readings outside thelimits. Index

  45. Why choose the Elcometer 224?How does it compare with other test methods?

  46. Surface Profile Test Methods Two other methods commonly used for measuring surface profile are: • Surface Comparators; • Replica Tape & Micrometer Thickness Gauge Index

  47. Surface Profile Test Methods Surface Comparators Standard surface comparators are available as eithergrit, shot or sand and are used to compare freshlyblasted profiles to pre-defined profiles. Whilst surface comparators provide a useful indication of surface profile, it is a subjective test. As they rely on visual comparison, the interpretation of the profile is dependent on the user. Index

  48. Surface Profile Test Methods Replica Tape & Micrometer Thickness Gauge Replica Tape produces a numerical value for the profileand has the added advantage of providing a ‘proof oftest’ as the tape can be included in manual reports(if stored correctly). The foam side of the tape is rubbed into the surface, providing a permanent mould of the peak-to-valley profile which can then be measured using a micrometer thickness gauge. Index

  49. Surface Profile Test Methods The tape is available in four ranges for different profile ranges; • Coarse minus (C-) (not used in blast profiles) • Coarse (C) for 20-38μm (0.8-1.5mils) profiles • X-Coarse (XC) 64-115μm (2.5-4.5mils), • X-Coarse plus (XC+) for profiles between 115-127μm (4.5-5.0mils) Due to recent changes in the technical specification, in some cases, more than one test has to be undertaken with different grades of tape. Index

  50. Surface Profile Test Methods • If a measurement is made with Coarse grade tape which is greater than 38μm(1.5 mils), a second measurement must be taken at the same spot with the X-Coarse grade. • If BOTH readings are between 38-64μm (1.5–2.5mils), the average of the two measurements should be taken as the surface profile. • If the reading taken with the X-Coarse grade tape is between 38-64μm (1.5–2.5mils) then a second measurement must be taken with the Coarse grade at the same spot, and the average recorded as the surface profile. • Finally, if the measurement taken with the X-Coarse grade is above 64μm (2.5mils), then this single measurement should be recorded as the surface profile at this spot. In this case the measurement taken with the Coarse grade should be discarded. It is important to note that in this case, both tape grades must be in the inspector’s toolkit as simply taking one grade will not be sufficient to record an accurate profile measurement. Index
