displayed. The instrument can also ignore some digits and alarm when the
values of some digits are satisfied. Use “.” on the numeric keyboard to set the
digits to be ignored and the corresponding position will display “x”.
Key Points:
1 You must complete the measurement configuration and scaling configuration
before configuring the alarm parameters. If you change the measurement
configuration or enable scalling function, alarms are turned off and the limit
values are cleared.
2 If you remove a channel from the scan list, alarms are no longer evaluated on
that channel but the limit values are not
cleared. If you decide to add that
channel back to the scan list, the original limit values are restored and alarms
are turned back on.
