Hart.transmitter.calibration.(Pressure.versus.current) - Crystal nVision Reference Recorder Operation Manual

HART.Transmitter.Calibration.(Pressure.versus.Current)

The nVision is capable of calibrating a pressure transmitter:
1
Modules Required: PM (Pressure) and MA20 (Current & Voltage).
2
Determine if HART transmitter is present.
If not, then proceed to Transmitter Calibration
(Pressure versus Current) section.
3
Select desired Current mode (mA, or % 4 –
20mA) using the Setup button.
4
Change the nVision to the Dual Numerical
Screen or any other preferred screen view.
5
Select the proper pressure units for your
nVision using the Setup menu.
6
Connect the nVision as shown.
7
Vent pressure source and Zero (- - - - -) the
nVision pressure module.
8 Apply pressure profile. Test or record pressure
and current readings as required.
9 Before disconnecting the nVision, isolate and
vent the pressure system. Disconnect and
return to service.
