6.4 Combined Accuracy
Peak Display Accuracy
6.4.4 Method of Calculation
This section describes the method of calculation by assuming that
measurement is performed in AC A mode using the 9692.
Total error when displayed value is 160.0 A (60 Hz)
Total error = ± (1.3%rdg. + 0.3 A)
*1
= ± (2.08 A + 0.3 A)
*2
= ± 2.3 A
True value when 160.0 A is shown: 157.5 A to 162.3 A
*1 See the accuracy at 10 to 66 Hz in AC mode for H range in the
9692+3290-10 combined display accuracy table on page 124.
*2 rdg. error = 160 A x 1.3%
Total error when REC output is 1.2 V (60 Hz) (for L range)
Total error = ± (1.8%rdg. +10 mV)
*3
= ± (21.6 mV+10 mV)
*4
= ± 31.6 mV
True value of 1.2 V output: 1.1684 V to 1.2316 V
(11.684 A to 12.316 A in terms of current)
*3 See the REC Output Accuracy at 10 to 66 Hz in AC mode for L
range in the 9692+3290-10 combined REC output accuracy
table on page 124.
*4 rdg. error = 1.2 V x 1.8%
