• 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, open circuit allows least significant digit
<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: Φ5×20mm, FF 400mA, H 600V, Breaking capacity: 500 A min., Input terminal
protection (μA, mA)
