Alternatively, adjust the values using the menus: 1. - Page 20 11.2 HIGH SPEED SCAN Although your gauge excels at making single point measurements, it is sometimes desirable to examine a larger region, searching for the thinnest point. The gauge includes a feature, called SCAN MODE, which allows it to do just that. This mode increases the overall repetition rate to a maximum of 50Hz with a high speed screen refresh rate of 25 times a second.
