Recommended Test Equipment
The test equipment recommended for the performance verification and
adjustment procedures is listed below. If the exact instrument is not available,
use the accuracy requirements shown to select substitute calibration
standards. If you use equipment other than that recommended in Table 3-1, you
must recalculate the measurement uncertainties for the actual equipment
used.
Table 3-1. Recommended Test Equipment
[1]
It is recommended to use a current monitoring resistor after calibration to
find the accurate resistance.
