μ
F, it is recommended to use the REL mode to deduct the open-circuit reading
• Accuracy guarantee: 1~100% of range
• For ranges of 60 mF. the measurement time is about 20 s

• The AC crest factor can be
≤
3.0 at 3000 counts, and can only be
≤
1.5 at 6000 counts. The additional
error should be added according to the crest factor of a non-sinusoidal wave, as follows:
a. Add 4% when crest factor is 1~2
b. Add 5% when crest factor is 2~2.5
