A.3 Daily Verification
Before subsequent use the of the Triax 2015 system the reference pad procedure (three
drops at specified height) is to be repeated. The average of the second and third drop
must be within +/-5% of the Initial Reference Pad Averages.
If the Initial Reference Pad Averages are not within the specified range contact technical
support before proceeding. When performing the reference pad procedure on surfaces
other than that which was used to establish the Initial Reference Pad Averages variation
greater than +/-5% may be observed. If in doubt contact technical support before
proceeding.
NOTES:
1. Reference pad values should be recorded and be included in every test report.
2. There are no user accessible means of performing calibration or adjustments.
A.4 Calibration
All electronic measuring instruments require initial and periodic calibration. Many
instrument manufacturers recommend a calibration interval of one year. Due to the use of
the reference pad procedure to verify instrument operation between factory calibration
the Triax 2015 calibration interval is extended to two years. Users may elect to calibrate
their instruments on the tradition one year (or shorter) interval as may be required by
their respective quality or other policies.
