Making Measurements

The following pages show how to make measurement connections and how
to select measurement functions from the front panel for each of the
measurement functions.
For remote operation, refer to the MEASure Subsystem in the Agilent
34405A Online Programmer's Reference online help.

Measuring AC or DC Voltage

AC Voltage:
• Five Ranges: 100.000 mV, 1.00000 V, 10.0000 V, 100.000 V, 750.00 V
• Measurement Method: AC coupled true rms - measures the AC component with up to 400 VDC
• Crest Factor: Maximum 5:1 at full scale
• Input Impedance: 1 MΩ ± 2% in parallel with <100pF on all ranges
• Input Protection: 750V rms on all ranges (HI terminal)
DC Voltage:
• Five Ranges: 100.000 mV, 1.00000 V, 10.0000 V, 100.000 V, 1000.00 V
• Measurement Method: Sigma Delta A-to-D converter
• Input Impedance: ~10 MΩ all ranges (typical)
• Input Protection: 1000V on all ranges (HI terminal)
