Measurement tolerances
Statement of accuracy in ± (% of reading + display error in counts (= number of smallest points)). The
accuracy is valid for one year at a temperature of +23°C ±5°C, and at a relative humidity of less than
75%, non-condensing.

mAμA range: F1 fuse 6 x 32 mm F 0.2 A H 600 V (CE) Item no.: 433005
10A range: F2 fuse 6 x 25 mm F 10 A H 600 V (CE) Item no.: 700161
Measuring operations of >5 A may only be performed for at most 10 seconds with a subsequent
measuring pause of 15 minutes.
