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 A-2, you must recalculate the measurement
uncertainties for the actual equipment used.
Table A-2 Recommended Test Equipment
*
To find the accurate resistance, it is recommended to use a current monitoring resistor after calibration.
