3-9. VOLTAGE MEASUREMENT ACCURACY

This test verifies the DC voltage measurement accuracy of the instrument. This procedure uses a dual cur- sor measurement that nullifies offset error, resulting in the following measurement:

± [(1.5% of full scale) + (0.016 x V/div)].

Specification:

±[(1.5% of full scale + offset accuracy) + (0.008 x V/div)]

Equipment Required:

The following equipment is required for this test. Procedures are based on the model or part numbers rec- ommended.
