Performance Test Record Verification Tests
DC Compliance Current Measurements
The 100 V range is used for the compliance current test. (The compliance current
is inferred from the voltage developed across the resistor).
M.U. = ± (0.035% of r 0.0006% of range)
M.U. = ± (0.00042 + 0.0006) = 0.00102 V
DC Short Circuit Current Measurements
The 100 mA range is used for the short circuit current measurement.
M.U. = ± (0.030% of r 0.005% of range)
M.U. = ± (0. 0.000005) = 0.000023 A
Current Output Measurements
The 100 mA range is used for the current output measurements.
M.U. = ± (0.030% of r 0.005% of range)
Test Accuracy Ratio (TAR)
The Test Accuracy Ratio (TAR) is defined as:
Where Maximum Allowed, Input, and Measurement Uncertainty are all in Vdc or
Amps.
The TAR is listed in table 4-1.
