either of the two following calibration intervals.
Performance Based Method
Determine need to calibrate by performing weekly check-runs of certified
viscosity reference standards. It is recommended the results of these runs
be recorded and compared against the certified viscosity value printed on
the standard bottle. When these check-runs consistently exceed the required
precision (typically > 2 or 3%), then the instrument should be calibrated. This
method requires more user interaction, but affords the least amount of risk
that the instrument could be used when out-of-calibration.
Periodic Interval Method
On a 12-month basis, the instrument is returned to CANNON
® Instrument
Company for calibration and certification regardless of the prior usage and
performance. This method requires the least amount of user interaction with
the instrument, but does afford some risk as errant calibrations (if present) will
only be corrected once every 12 months.
Verifying Temperature
Periodically, the temperature should be verified with
a digital reference thermometer. The temperature
should be recalibrated if the displayed temperature
does not agree with the reference thermometer.
Note: Please contact CANNON
® Instrument
Company for details on suitable reference
thermometers.
The user may access Temperature
Calibration Screen from the Ready to Test
Screen by tapping the temperature field 3 times within 2 seconds. The
Temperature Calibration Screen will appear in which the user may
enter the temperature as read from the reference thermometer to the nearest
0.01°C. This may need to be repeated if the temperature still does not agree
