CalibrateANSI/ISA–S51.1–1979 (R1993)

Calibrate: To ascertain outputs of a device corresponding to a series of values of the quantity which the device is to measure, receive, or transmit. Data so obtained are used to:

1) determine the locations at which scale graduations are to be placed;

2) adjust the output, to bring it to the desired value, within a specified tolerance;

3) ascertain the error by comparing the device output reading against a standard.

Malaysia End-User Seminar11 November 200925

Calibration- What does it mean?

1. Determine the locations at which scale graduations are to be placed;

– Set the 4 mA and 20 mA points (range)– Scaling/ranging can be done remotely without applying input– Scale/range not applicable to most fieldbus transmitters

2. Adjust the output, to bring it to the desired value, within a specified tolerance;

– Trim the output current– Need to connect a multimeter– Not applicable to fieldbus

3. Ascertain the error by comparing the device output reading against a standard.

– Trim the sensor reading– Need to apply input (e.g. equalize and vent manifold to zero)– Is applicable to fieldbus

Malaysia End-User Seminar11 November 200926

Calibration for Fieldbus

•Sensor Trim– If measurement reading is

wrong it must be corrected• E.g. correct for mounting position

– From transducer block– Need to apply input

• Done in the field

• Configure Range/Scale Setting

–Zero and Span• In PID block (valve or

controller)• In AI block for inferential

measurements such as DP flow and DP level

• Some transmitters may need range to operate

• Cancel wet-leg etc.–Set the portion (range/scale) between sensor limits which is of interest for application

–In function block–Just setting a value

•Done remotely from control room

Malaysia End-User Seminar11 November 200927

Calibration Trim

• Methods simplify complex tasks

• Ensure correct procedure

• Eliminates mistakes

Malaysia End-User Seminar11 November 200928

Field Calibration Trim Tools

• Field Communicator– Plus calibrator– Clipboard for notes

• Documenting calibrator– With Fieldbus interface– Mainly pressure and

temperature

Reduce Paper Work

Malaysia End-User Seminar11 November 200930

Why do I need a handheld field communicator?

• Field tasks– Sensor trim

• Turn manifold– Cancel wet-leg

• Verify empty– Valve stroking

• See it move– Repair

• If it indeed failed

• Laptop/tablet– Heavy– Moving parts– Usually not rugged– Not hazardous area

certified– Limited battery life

Malaysia End-User Seminar11 November 200931

Are Handhelds and Device Management Software The Same?

• Information content & structure– Same, because determined by the device

manufacturer, not the system/handheld• Look & feel

– Slightly different, because dependent on the platform• Screen size, color, keyboard, mouse...

• Features– Different

• Device management software is permanently connected• Device management software has a database

– Audit trail, scheduling, persistent data storage, manuals, other documents etc.

Malaysia End-User Seminar11 November 200932

Conclusion

• You don’t have to go to the field as often– Diagnostics and configuration done remotely

• You still need to go to the field sometimes• Working in the field is easier than in the past• Specialized tools and solutions for fieldbus are

available• Fieldbus is not difficult
