9694 CLAMP ON SENSOR
Accuracy of the combination of the 9660/9661/9669/9694 and the
3196:
Example: Using the 9661, 50 A range setting (3196), when measuring 50 Arms
Error of 9661 + Error of 3196 = Total error
Error of 9661 = 50 A(measurement) x 0.3% rdg. + 500 A(rating) x 0.01% f.s.
= (50 x 0.3/100) + (500 x 0.01/100)
= 0.15 + 0.05
= 0.20 A
Error of 3196 = 50 A (measurement)x 0.2% rdg. + 50 A (range) x 0.1% f.s.
= (50 x 0.2/100) + (50 x 0.1/100)
= 0.1 + 0.05
= 0.15 A
Total error = 0.20 A + 0.15 A
= ±0.35 A
