Hello Thanks for your question. No, It is not possible to calibrate beyond name plate range. You need to calibrate TT in -50 degree C to -450 degree celsius.
Well am a process technician but I want to diversify into instrumentation. how do I start please? I listen to your videos on Hart communicator i was only able to grasp very few things. please help.
Hello Okotete You can start your instrumentation journey with our some basic video on Instrumentation.

I have a Rosemount Temperature Transmitter and I need to apply above 20.5 mA to check the Over-range alarm setting however I am not able to sent above 20.5 mA through HART as the Transmitter is not accepting the mA above 20.5 mA. Could you please suggest any options to check the Over range alarm
No. first you check transmitter mounting plat. Then you check it's 2 wire, 3 wire, 4 wire wire duel sensor. They mention in mounting plate. Then only you set 2,3,4 wire RTD.
