Maximum reading (MAX). Press and hold the yellow STATS button again to display the Mean reading
(MEAN) and the Standard Deviation (SD) of the readings.
Dual and triple angle Glossmeters have separate sets of data and statistics for each angle.
Statistics mode may be exited by pressing the STATS button once (activating the 2nd function), and then a
second time. Alternatively, pressing any of the function keys, such as READ or OUTPUT, will exit statistics
mode and perform that function. If the gauge switches off while it is in statistics mode it will automatically
return to normal mode on switching on again.
Statistics are defined below. For this purpose the individual readings are defined as values x
