Performance Test Record

Table 2-1, "Performance Test Record for the E1364A Switch Module," is a form you may copy and use to record performance verification test results for the switch module. Pages 3 and 4 of Table 2-1 show switch accuracy, measurement uncertainty (M.U.), and test accuracy ratio (TAR) values.

Switch Accuracy Accuracy is defined for closed-channel contact resistance and DC isolation using the specifications in Appendix A of the E1364A User’s Manual. The closed-channel resistance and DC isolation specifications are single-sided, meaning that there is an upper limit OR a lower limit, but not both. In Table 2-1, either the "Minimum" or "Maximum" column will be blank for a single-sided test.

Measurement Uncertainty

Closed-Channel Resistance Test

DC Isolation Test

Test Accuracy Ratio (TAR)

For the performance verification tests in this manual, the measurement uncertainties are based on 90-day accuracy specifications for the 3458A Digital Multimeter. The calculations are shown below.

Conditions:

4-wire ohms function

10 range

90-day specifications

Worst-case reading = 3.5

M.U. = 15ppm of Reading + 5ppm of Range = 15 x 10-63.5 + 5 x 10-610 ()

= 1.03 x 10-4

Conditions:

2-wire ohms function

1 Grange

90-day specifications

Worst-case reading = 1.2 G(highest resistance that can be measured with the 3458A)

M.U. = 0.5% of Reading + 10ppm of Range

= 0.005 1.2 x 109

+ 10 x 10-61 x 109 (Ω)

= 6 x 106

 

Test Accuracy Ratios are not defined for single-sided measurements, so all closed-channel resistance and DC isolation measurements have "NA" (Not Applicable) in the TAR column.
