9-14 Limits and Digital I/O Model 2750 Multimeter/Switch System User’s Manual
NOTE When measurements are performed, the readings are fed to other enabled oper-
ations, including Limits. Appendix D explains “Data flow (remote operation)”
and the commands used to read the result of limit tests.
Reference
a. CALCulate3:LIMit1:STATe <b> [, <clist>]
CALCulate3:LIMit2:STATe <b> [, <clist>]
Unlike front panel operation, Limit 1 and Limit 2 can be controlled (on/off) sepa-
rately for remote programming. The front panel limit indicators are affected as
follows:
Limit 1 enabled — The front panel HIGH/IN/LOW indicators work the same as
they do for front panel operation.
Limit 1 disabled and Limit 2 enabled — The status indicators pertain to Limit 2.
When the reading is within Limit 2, the message “I2” is displayed. When the read-
ing reaches or exceeds the high or low limit, the HIGH or LOW annunciator will
turn on, and the number “2” will be displayed.
NOTE When limits are disabled from the front panel, both Limit 1 and Limit 2 disable
for remote operation.
