Dear Brother Ali,
Can you provide us whether you going to calibrate Analog
transmitter or SMART transmitter?
If Analog transmitter means No way
If SMART means you can change your LRV and URV online.It
doesn't mean full calibration but it will adjust the
transmitter output according to LRV/URV

Answer / debyendu

we can calibrate transmitter with a hart communicater which
is to be connected with 250 ohm resistance in series with
transmitter to the power supply unit.

The wire is disconnected from the fuel gauge sending unit (bimetallic gauge). A voltmeter connected to the wire reads a pulsating 5v. What does this indicate?
