The terms button and hard key refer to all of the buttons on the instrument face. These keys perform as follows:

Press the Menu key to display the Menu Key Screen, a grid of shortcut icons for installed measurement modes and user‑selected menus and setup files.

Press this button to turn on power to the PIM Master. Press and hold this button to turn off power.

 

The four Arrow keys are used to scroll up, down, left, or right. The Arrow keys can often be used (depending upon measurement selection) to change a value or to change a selection from a list. In some measurements, the Left/Right arrow keys change values by different increments than the Up/Down arrow keys. The Arrow keys are also used to move markers.

Press this key to finalize data input.

Press the Shift key and then press a number key to open the menu that is indicated in text above the key number. When the Shift key is active, its icon is displayed at the top‑right of the measurement display area between the battery charge indicator and the submenu key labels.

Press this key to cancel any setting that is currently being made.

Press these keys to directly input numbers. Number keys are also used to open menus when used with the Shift Key. For example, press Shift and Touch (0) to initiate Touch Screen Calibration.

Press this key to change the sign of numbers that are entered with the number keys.
