LEAKCK(=)
Purpose Starts a molbox RFM or system leak check cycle or checks if a
cycle is complete.
Syntax "LEAKCK=type(,microrange)"
"LEAKCK"
Arguments type:
microrange:
Remarks This command is used to start and monitor the progress of the
leak check. Both "BOX" and the "SYS" leak checks take 60
seconds to complete. At the end of the leak check, the molbox
RFM is returned to its normal operating state. For the "BOX"
leak check, the microrange RPT is normally bypassed
(inactive) unless the optional second argument is given. For
the "SYS" leak check, the microrange RPT is always
bypassed.
The "ABORT" command can be used to stop a leak check
cycle, clear out any previous error messages, and return the
molbox RFM to its normal operating state.
check cycle is executing, a 'b' ("busy") will appear in the third
character position of the "FR" and the "SR" command replies.
If the leak check failed, an error will be replied to the
"LEAKCK" query until the "ABORT" command is used to abort
the leak check. When the leak check has completed without
an error, the "LEAKCK" query will reply "OK".
The "LEAKCK" command must be completed or aborted using
the "ABORT" command before performing other operations.

and venting ports before the leak check is
executed.
"SYS" starts a leak check cycle on the system
connected to the molbox RFM. The system
must be prepared for the leak check by setting
pressures and operating valves before the leak
check is executed.
'0' If the 'type' specified is "BOX", then the
microrange RPT will be bypassed (inactive)
during the leak check cycle.
'1' If the 'type' specified is "BOX", then the
microrange RPT will NOT be bypassed (active)
during the leak check cycle.
