When the measured current is >5 A, each measurement time should be ≤30 s and the rest interval should be
≥15 minutes.
• True RMS display.
• Frequency response: 40 - 400 Hz.
•
Accuracy guarantee range: 5 - 100 % of range, short circuit allows least significant digit <2.
•
The AC crest factor is ≤3.0 when measured at 3000 counts. The full range AC crest factor of 6000 counts is
≤1.5.
• Non-sinusoidal waveforms:
- When the crest factor is 1.0 - 2.0, the accuracy must be increased by 4.0 %.
- When the crest factor is 2.0 - 2.5, the accuracy must be increased by 5.0%.
- When the crest factor is 2.5 - 3.0, the accuracy must be increased by 7.0%.
• Overload protection:
-
F1 Fuse: μA mA range, ø6 x 32 mm, 0.6 A H600 V FF(CE)
- F2 Fuse: 10A range, ø6 x 25 mm, 10 A H600 V FF (CE)
