Calibration Tests and Adjustment
The Test Board
Calibration Tests
These procedures test the probe’s electrical performance using applicable specifications
given in “Performance Specifications and Characteristics” on page 55 as performance
standards. Specifications applicable to individual tests are noted at the test for reference.
Testing Interval
The calibration testing procedures may be performed for incoming inspection of the
instrument and should be performed periodically thereafter to ensure and maintain peak
performance. The recommended test interval is yearly or every 2,000 hours of operation.
Amount of use, environmental conditions, and the user’s experience concerning need
for testing will contribute to verification requirements.
Calibration Test Record
The results of the calibration tests may be tabulated in the Calibration Test Record
provided at the end of the calibration tests. The Calibration Test Record listed the
calibration tests and provides an area to mark test results. The results recorded in the
Calibration Test Record during initial inspection may be used for later comparisons of
the tests during periodic maintenance, troubleshooting, and after repairs or adjustments.
Calibration Test Procedures
Procedures may be done individually or in any order.
NOTE Allow the instrument to warm up for at least 30 minutes prior to beginning calibration
tests.
