Using The Function Modifiers In Combination; Second Level Operations (Using The Shift Button) - Fluke 8808A User Manual

Using the Function Modifiers in Combination

You can use multiple function modifiers simultaneously.
Selected modifiers are evaluated in the following order: Touch Hold,
minimum/maximum, and then relative readings. The Meter first looks for a stable
measurement for Touch Hold, then determines if the measurement is a new minimum or
maximum value, and then subtracts the relative base from the measurement.
When using multiple modifiers, the order in which you select the modifiers affects how
the modes will respond. For example, if you are in minimum/maximum mode, if you
press T, the value currently displayed becomes the relative base. Pressing N then
displays the difference between the minimum and maximum values. Additionally, if you
are in the relative readings mode, pressing N displays the difference between the
relative base and the minimum or maximum value (as applicable).

Second Level Operations (Using the SHIFT Button)

Pressing Q causes the next button pushed to perform its second level operation. Second
level operations are printed in red on their respective buttons. When Q is pressed,
S is displayed.
See Table 3-6 for descriptions of second level operations and the buttons used to invoke
the operations.
