10.4Calibrating PV1 and PV2 Range Values

Background

ATTENTION

The SMV 3000 Smart Multivariable Transmitter has two-point calibration. This means when you calibrate two points in the PV range all the points in that range adjust to that calibration.

You must have a precision pressure source with an accuracy of 0.04% or better to do a range calibration. Note that we factory calibrate SMV 3000 Smart Multivariable Transmitters with inches of water ranges using inches of water pressure referenced to a temperature of 39.2 ° F (4° C).

Procedure

Depending if you are using the SCT 3000 or the SFC to perform

 

calibration, refer to the appropriate sections below for the procedure. The

 

procedures show you how to calibrate the PV1 and PV2 ranges (LRV and

 

URV) of the transmitter. This procedure assumes that the transmitter is

 

removed from the process and located in a controlled environment.

 

See Figure 28 for typical SCT/SFC, power supply, and pressure source

 

hookup for calibration.

 

Using the SCT, select the topic:

 

“Calibrating LRV and URV for an SMV 3000 Transmitter”

 

and Click on “Input Calibration – (for the desired PV listed

 

in the menu)”.

 

The procedure for setting PV1 range is viewed by selecting

 

“Steps to Calibrate LRV and URV for PV1”.

 

The procedure for setting PV2 range is viewed by selecting

 

either “Calibration Procedure Using an Absolute Pressure

 

(Vacuum) Source” or “Calibration Procedure Using a

 

Gauge Pressure Source with an Absolute Pressure

 

Readout”.

 

Using the SFC:

 

Follow the procedure for “Calibrating Measurement Range

 

for PV1” and “Calibrating Measurement Range for PV2”in

 

Section 7 of the SFC Operating Guide.
