Manual
Press Alt + 1 to enter manual mode. This option enables you to manually control the Bypass, Fill,

Transmit
Press Alt + 3 to transmit report data over a serial line. If you attempt to transmit data during an auto-

The AccuPyc RS-232 interface transmits report data to a computer using the standard ASCII file for-
mat. Once captured with a serial communications program such as HyperTerminal (included in most
Windows installations), the report data can be imported into popular spreadsheet and data manipula-
tion programs.
Press
Alt + CLEAR to cancel report data sent to the serial line.
Reports may be transmitted in a single-column format or a spreadsheet format. Refer to TRANSMIT-
TED DATA, page D-1 for a description of the formats.

open and close the Fill, Expansion, and Vent valves by
pressing the appropriate keys.

The three characters in the second line of the display show
the state of the valves, where:
First character = Fill valve
Second character = Expansion valve
Third character = Vent valve
X = Closed
O = Open
Press
SAVE to exit manual mode and return to display mode.
Prolonged opening of all three valves at one time may cause excessive loss of helium.
