Error message

Error: 260118224 60-0403 mA out of range See Long Description for complete error Thu Jun 9 14:36:46 2005 260118224 orp orp_subsys gen_exec.c 2150 Host : Jedi Exception Class : Soft Severity : Pri/Soft File : gen_exec.c Line# : 2150 Function : No System Function Reported Scan Type : Helical Scan: 10105/2/5 (60-0403)mA out of range Measured mA every 50 msec exceeded 5 percent of mA demand.This error is logged, but does not stop the exposure. Z6,Z7= 0h,0h Note: MA Out Of Range (60-0403) error may be bogus depending on mA scanning mode. If this error occurs during a Helical AutomA scan, please ignore. Jedi Error # 260118224 (60-0403) “Measured mA every 50 msec exceeded 5 percent of mA demand” is an informational message intended to identify a possible mA stability issue. This error is logged but does not stop the exposure. If this error happens during a fixed mA scan it could indicate a problem and should be investigated further. But, if this error occurs during a helical with automA, this error should be ignored. In the automA mode, the mA is constantly changing and therefore this message does not indicate a real problem.
