• 10 Amp AC Current or DC Current Range
• Shunt Resistance: 0.01 Ω for 10A range
• Internal 15A, 600V fuse for 12A terminal
Typical ACI Display:
A AC
Typical DCI Display:
A DC
• Five Ranges: 100.000 mV, 1.00000 V, 10.0000 V, 100.000 V, 750.00 V. Range is
based on the voltage level of the signal, not frequency.
• Measurement Method: Reciprocal counting technique.
• Signal level: 10% of range to full scale input on all ranges
• Gate Time: 0.1 second or 1 period of the input signal, whichever is longer.
• Input Protection: 750V rms on all ranges (HI terminal)
