About the Keypad

  A keyboard can be connected to the USB port on the rear panel of the AccuPyc II. Commands can be entered from either the keypad or the keyboard.

Most keys on the keypad perform one primary and one alternate function. The primary function of any key is indicated by the number or command on the face of the key. The alternate function is indicated by the command above the key. The top right corner of the display screen will show a + (plus sign) when the Alt key is pressed and the alternate function mode is entered. See About the Display.

To select the:

  • Primary function. Press only the key. Primary functions are labeled on the key face. For example; press 4 to enter the number 4.
  • Alternate function. Press Alt, then press the key. Alternate functions have blue labels above the key. For example; press Alt + 4 to start an analysis. If the Alt key is pressed accidentally, pressing it a second time will cancel its function.

The alternate functions for keys 7 (FILL), 8 (EXPAND), and 9 (VENT) are executed differently. Press Alt + 1 first to enter Manual mode then press the alternate key. For example: press Alt + 1 + 7 to manually control the Fill valve. Press Alt + CLEAR to exit Manual mode.

Functions can be entered from the keyboard.
