Note!
Observe maximum allowable voltage for connection from external
sources to the calibrator output if current sink is selected: U
ext
0 to
27 V. The calibrator is protected against brief application of a large
interference voltage with a replaceable fuse in the event of
operator error., i.e. in case of overloading (> I
max
/U
max
) the fuse
may blow.
Simulator for Temperature Sensors (resolution: 0.1 K)
* Without internal reference junction;
relative to fixed external reference temperature
and thermovoltage of the thermocouple,
Regarding additional error see also the table on page 26.
Internal reference junction: 2 K intrinsic error
External reference junction: entry of –30 to 60 C
