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.
