6.5.1 Temperature Simulation for Resistance Thermometers –
RTD Temperature Setting
Resistance temperature detectors (types Pt100, Pt1000, Ni100
and Ni1000) are simulated by means of resistance values.
Abbreviated Instructions

Activate output :
Response time of the calibrator output to the specified resistance
value after measuring current is applied is max. 30 ms.
Devices under test with non-continuous measuring current (e.g.
scanned measuring inputs) result in erroneous measured values,
if measurement is started before response time has elapsed. The
calibrator cannot be used for devices of this type.
6.5.2 Temperature Simulation for Thermocouples –
TC Temperature Setting
Thermocouples (types B, E, J, K, L, N, R, S, T and U) are
simulated with voltage. Internal or external temperature
compensation is possible.
