Clean the Calibrator
Clean the case, front panel keys, and display with a soft cloth dampened with water or a
non-abrasive weak cleaning solution that will not harm plastics.
Caution
Do not use aromatic hydrocarbons or chlorinated solvents for
cleaning. They can damage the plastic materials used in the
calibrator.
Performance Tests
To make sure that the Product is in specification, use Tables 7-3 through 7-15. The tables
are for approved metrology personnel who have access to a standards laboratory that has
the correct equipment to test calibration equipment of this level of accuracy. The tables
show the recommended test points and the permitted maximum and lower limits for each
point. The limits were calculated by adding or subtracting the 90-day specification from
the output value. There is no built-in factor for measurement uncertainty.
