OUTPut:ALARm:MODE {LATCh|TRACk}
OUTPut:ALARm:MODE?
Only supported on multiplexer modules (DAQM900A, DAQM901A, DAQM902A, and DAQM908A) and
DAQM907A multifunction module.
Selects the output mode for all four alarm output lines.
Latch Mode: The alarm output is asserted when a channel's reading crosses a limit, and remains asserted until you
clear it manually, start a new scan, or cycle power.
Track Mode: The alarm output is asserted when a channel's reading crosses a limit, and remains asserted only while
subsequent readings remain outside the limit. When a reading returns within the limits, the output is automatically
cleared.
Parameter Typical return
{LATCh|TRACk}
Default: LATCh
LATC or TRAC
Enables the track mode on all four alarm output lines: OUTP:ALAR:MODE TRAC
– A Factory Reset (*RST command) clears all four alarm outputs but does not clear the alarm queue in either con-
figuration.
– You can manually clear the output lines at any time (even during a scan) and the alarm data in reading memory is
not cleared. However, data is cleared when you initiate a new scan.
