When the following subprogram is called (CALL EXTPACE), the multimeter
executes it line-by-line until it encounters TARM EXT (line 70). Subprogram
execution then ceases until an external trigger occurs. This allows you to
synchronize subprogram execution to some external event. After the first external
trigger is received, subprogram execution resumes. When the next line is
encountered (TRIG SGL), subprogram execution ceases until the 1000 readings
are taken. After the readings are taken, the subprogram changes the
measurement function to 2-wire ohms and the number of readings to 100. When
the second TARM EXT command is encountered (line 100), subprogram execution

removed). If you compress a subprogram, however, (COMPRESS command)
the subprogram is removed from continuous memory and will be destroyed
when power is removed.
