RTD Specifications
Note
Since ohms input and output units are available, you
can use the calibrator for any unsupported RTD type by
selecting the ohms range and making manual
calculations or referring to tables.

Addresses pulsed transmitters and PLCs with pulses as short as 5 ms.
Allowable Excitation is for Output mode only. It shows the allowable excitation
current from an ohmmeter or RTD measurement device connected to the
calibrator.
Excitation current from 712: 0.2 mA.
Maximum input voltage: 30 V
