Measuring Ac (Rms) Or Dc Current Up To 12A; Measuring Frequency - Agilent Technologies 34405A User's And Service Manual

1 Getting Started Tutorial

Measuring AC (RMS) or DC Current up to 12A

• 10 Amp AC Current or DC Current Range
• Shunt Resistance: 0.01 Ω for 10A range
• Internal 15A, 600V fuse for 12A terminal
ACI
DCI

Measuring Frequency

• Five Ranges: 100.000 mV, 1.00000 V, 10.0000 V, 100.000 V, 750.00 V. Range is based on the voltage
• 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)
