To zero the Rosemount 2051, first close the block valve on the low pressure (downstream)
side of the transmitter.
Note
Do not open the low side equalize valve before the high side equalize valve. Doing so will
overpressure the transmitter.
Open the equalize valve on the high pressure (upstream) side of the transmitter.
