8.3.3 Programs 1-3
Measurements can be controlled via 3 freely definable measuring/saving programs. The
channel, starting criteria, measuring rate, measurement duration or number of values are
defined in the programs 1-3. The programs are started once the “starting criterion” is ful-
filled. The starting criterion is checked at the measuring rate: if a slow rate has been set it
is advisable to set a an intermediate rate when checking the starting criterion (see Chapter
8.6.5). All 3 programs can be started independently of each other, they save all of the con-
nected probe values at the set measuring rate. “Programming 1” can be taken as an exam-
ple for all 3 programmings.
