The Elcometer 456 Models S and T have the Counted Average function as standard and this can be used to set the number of readings in each area or spot and the gauge will then store the average of these individual readings in the memory of the gauge. The Fixed Batch Size feature on the Elcometer 456 T version allows the maximum number of readings to be defined by the User for each batch. Once this number of readings have been collected and stored, the gauge automatically closes the batch and opens a new batch linked to the previous batch, e.g. name-1, name-2, etc. Specifications for coating thickness determination often describe the number of individual thickness readings to be taken as a spot measurement and the number of spot measurements for a given area. For example, SSPC PA-2 requires three gauge readings per spot and five spot readings in a 10 m² area. With the Ultra/Scan Probe connected to the Elcometer 456 T version with the Auto Repeat function selected, SSPC PA-2 (or similar test specification) can be completed for a given area more than 40% faster than with the more traditional measurement. A counted average setting of three readings and a fixed batch size of five spot readings allows the coating thickness readings data defined by SSPC PA-2 to be collected with each inspection area being contained in its own batch. The ElcoMaster ® software and the USB and Bluetooth ® gauge connectivity allows the resulting data to be transferred to a computer either directly using the USB cable connection or wirelessly using Bluetooth ® . These features are suitable for Cloud Computing so that data can easily be transferred via the Internet using the ElcoMaster ® Mobile App. Elcometer Bluetooth ® enabled inspection gauges can be connected directly to iPhone, iPad, iPod or Android™ mobile phones and tablets via ElcoMaster ® Mobile App. The software also provides the option for recording the location of the inspection site by using the GPS feature on the mobile device and tagging the batch locations in ElcoMaster ® .
