Pycnometer Keypad
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. When you press
Alt to enter the alternate function mode, a
+
(plus)
sign is shown in the upper right corner of the display.
To select the:
• alternate function , press
Alt
plus the key. For example; press
Alt + 4
to start an
analysis.
• primary function , press only the key. For example; press
4
to enter the number 4.
If you press the Alt key accidentally, press it a second time to cancel its function.
The alternate functions for keys 5 (BYPASS) ,
7
(
FILL
),
8
(
EXPAND
), and
9
(
VENT
) are executed dif-
ferently. You must first press Alt + 1 to enter Manual mode to access these commands. After you enter
Manual mode, you simply press the desired key to use the alternate function. For example: press
Alt +
1 + 7 to manually control the Fill valve. You must press Alt + CLEAR to exit Manual mode.
Tables 3-1 and 3-2 describe how the keys are used to control and monitor the pycnometer.
