Calibration What is calibration? Calibration Check Calibration Trim 23 Malaysia End-User Seminar 11 November 2009
Calibrate ANSI/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. 24
Calibration - What does it mean? 25 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
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 26
Calibration Trim Methods simplify complex tasks Ensure correct procedure Eliminates mistakes 27

Handheld Communicator Field Work 29 Malaysia End-User Seminar 11 November 2009
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 30
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. 31
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 32
