•
{CH1|CH2}:FILL:STATE?
Returns the state of the selected AC output ( CH1 prefix selects AC Output
1 and CH2 prefix selects AC Output 2) for all controller modes according to
the table below:
•
{CH1|CH2|AUTOCH|PRECOOL}:FILL:TIMEout < minutes >
Sets the timeouts associated with the various controller modes in minutes.
•
{CH1|CH2|AUTOCH|PRECOOL}:FILL:TIMEout?
Returns the timeouts, in minutes, associated with various controller
modes.
•
{CH1|CH2|PRECOOL}:FILL:ELapsed?
Returns the elapsed time of an auto-fill cycle that is subject to a fill
timeout setting. A return value of zero indicates that an auto-fill cycle is
not active, or a timeout value was not specified.
In normal mode, use the {CH1|CH2}:FILL:ELapsed? queries to return
the fill time for the auto-fill cycle of each respective channel.
In auto-changeover mode, use the CH1:FILL:ELAPSED? query to return
the elapsed time for an auto-fill cycle from either storage vessel.
In pre-cool mode, use the CH1:FILL:ELapsed? query to return the
elapsed time for the auto-fill cycle of the controlled dewar (return value
includes the pre-cool time). Use the
PRECOOL:FILL:ELapsed? query to
determine how long the vent valve has been open.
Table 5-5. Return characters and their meanings for the
{CH1|CH2}:FILL:STATE? query.
Return Characters Meaning
0, “OFF” AC output is de-energized.
1, “ON” AC output is energized.
2, “AUTO_OFF” AC output is under automatic control but is de-
energized.
3, “AUTO_ON” AC output is under automatic control and is
currently energized.
4, “EXPIRED” AC output is under automatic control and is
currently expired due to timeout condition or
remote contact sense, and is de-energized.
