Limit Testing

(continued)

•

Remote Interface Operation: You can use the following commands for
limit testing.

CALCulate:FUNCtion LIMit
CALCulate:STATe {OFF|ON}
CALCulate:LIMit:LOWer {<

value

>|MINimum|MAXimum}

CALCulate:LIMit:UPPer {<

value

>|MINimum|MAXimum}

•

There are two unused pins on the

RS-232

interface connector which

are available to indicate the pass/fail status of readings taken with
limit testing. To configure these pins for limit testing, you must
install two jumpers inside the multimeter. See the Service Guide for
more information.

A low-going pulse is output to pin 1 for each reading that is within
the specified limits. A low-going pulse is output to pin 9 for each
reading that exceeds the upper or lower limit.

C a u t i o n

Do not use the RS-232 interface if you have configured the multimeter to
output pass/fail signals on pins 1 and 9. Internal components on the
RS-232 interface circuitry may be damaged.
