Model: SF-670 SF-80 SF-60 SF-50
Accuracy: Class 1.5
Specification: 0.1A 0.5A 1A 7.5A 10A 15A 20A 25A 30A 40A 50A 60A 75A 100A
For 5A-10KA use external current transformer with secondary current 5A and 1A.
Notes: For 60A, 75A, 100A meters, when these meters directly connected to circuit, their accuracy is class 2.5.
For 20A-60A direct reading SF-48 meters, the accuracy is class 2.5.
Changeable scale: All scales with pringting technique.
The dial plate with different scale, which is at the same division and internal value, can be changeable.
But the accuracy is unchangeable
