Calibration Accurse The quality of freedom from crxor to which the trip setpoint is calibrated vith xospoct to the tsae desired setting, including both calibration instrmncntation accuracies and calibration procedure allowances. When associated <<ith the calibration instxu-ments, thi.s term is sometimes sefexxod to as "Resolution." The value specified is the mazimam value for two standard deviations (2a c ) of the probability distribution of calibration accuracy, 4~ Instrument Drift The chango in the value of tho process variable, at vhich the trip action vill actually oocur, between the timo the naninal trip sotpoint 'is calibrated and a subsequent surveillance test, dao to all causos, as moasusod in terms of the instsmnentation indicator scale, The valuo of tho procoss variable at which the trip action vill actually occur at the time. of calibration is taken to be thc intonded nominal tsip set point valuo. The valuo spocified is the mazimmn valuo for two standasd deviations (2ed) of tho probability distribution of instrmnont drift ST Nominal Txi Set Points NTSP - Tho intended calibration point at which a trip action is set to operate, commonly thc center of an accoptable range of trip operation.

'ont.,on Sheet Bp Checked:~"- '.- ~"---"- .-= -'pproved Tjtie VNSTRUCTION STEP 1. Complete all required information. 'f not applicable, mark NA.

STEP 2. Explain the function of the switch. Complete one of the following.

A) Identify if a Technical Specification applies or if the switch fuction is a protective limit. A protective limit is one which results in equipment damage or an unsafe condition if exceeded.

A tech. spec. or protective limit can also be in the form of a process function, alarm or indication, however, this step must be complied with.

B) Identify setpoints which are to control process functions, alarm that a condition exists or provide an indication. In-struments in this catagory are operator aids and are not tech. spec. or protective limit.

C) Identify and e~lain any additional catagories of instruments and select appropriate calculation method.

STEP 3. Enter allowable values (tech. spec. only) and trip setpoints as defined in definitions. Reference their respective engineering documents (e.g. drawing, calculation, vendor information). If this data is unavailable, STEPS 4-13 must be used to derive these values.

STEPS 4-9. Enter the required information and references. See Definitions.

STEP 10. Calculate the Allowable Value (AV). If a minimum limit (STEP 8) then, AV=STEP 9+STEP 4, if a maximum limit, AV=STEP 9-STEP 4.

STEP 11. Calculate the Trip Setpoint Limit. This value as calculated is as close as the setpoint can be to (AL). This value can be the actual setpoint or it may be established using the guidelines in STEP 12.

STEP 12. Setpoints must be established to perform the required function yet minimize inadvertent tripping due to operational transients. The following guidelines should apply or an improper instrument may be applied.

e STEP 8 (mz) + STEP 4 + STEP 6 <TRIP SETPOINT, OR STEP 8 (MIN) + STEP 4 STEP 6 >TRIP SETPOINT If STEP 2B, or, possibly 2C, is used, reference the source of or method used to determine the setpoint. Continue in Remarks section if necessary.

STEP 13. Enter the Trip Setpoint, both in process and instrument units, the Allowable Value (Tech. Spec. only), and note any Remarks which may be helpful in understanding how this calculation was completed.

1) Accuracy: Manufacturers rated accuracy in percent full scale.

2) Accuracy, Total Loop: The sum'f the instrument accuracies or, if desired, the square root of the sum of the squares of the instrument accuracies.

3) Analytical Limit (A.L.): The value of the sensed process vari-able prior to which a desired action is to be initiated to prevent the process variable from reaching the associated design/safety limit.

4) Allowable Value: Analytical Limit minus Total Loop Accuracy.

5) Instrument Drift Estimated change in instrument setpoint between calibrations.

6) Maximum Operating Point Normal plant process operating point plus normal operating transients.

7) Minimum Operating Point Normal plant process operating point

~inus normal operating transients.

8) NO/NC Contact Normally Open/Normally Closed contact used for switch function.

9) Reset Deadband Contact deadband between trip setpoint and contact reset (return to normal).

10) Switch No. & Circuit No. Identifies the switch and circuit within the instrument as identified by the instrument manufacturer.

ll) Trip Setpoint Limit - This value is as close to the Analytical Limit as the instrument can initially be set.
