2.7 Verify Calibration
For best results, verify the calibration daily.
Note: When not using the original transducer, calibrate the Model NK before use
(page 14).
1. Obtain the following values from the transducer calibration data sheet:
•
Shunt-cal output (or "shunt-cal factor") in mV/V
•
Calibration factor (or "full-scale output") in mV/V
•
Full-scale engineering units (or "capacity") in psig, lbs, etc.
2. Perform this calculation and record the value.
Note: Place a decimal point in the
the same place as set in the display.
3. With no load on the transducer, press and hold the
