Selecting Current Input Terminals And Measurement Range; Measuring Ac (Rms) Or Dc Voltage - Keysight 34450A Guia Del Usuario

Selecting current input terminals and measurement range

If AC or DC current is being measured in auto-ranging mode, with a signal input at
100 mA, the meter will select the range 100 μA to 100 mA automatically.
If a signal input is applied to the 10 A input terminal, the meter will select the 1 A
to 10 A range automatically.

Measuring AC (RMS) or DC voltage

AC Voltage:
– Measurement Range: 100.000 mV, 1.00000 V, 10.0000 V, 100.000 V, 750.00 V
– Speed: Slow-2 Hz, Medium-20 Hz, Fast-200 Hz
– Default Setting: Autoranging, Slow measurement speed
– Measurement Method: AC coupled true RMS - measures the AC component
– Crest Factor: Maximum 3:1 at full scale
– Input Impedance: 1 M ± 2% in parallel with <100 pF on all ranges
– Input Protection: 750 V rms on all ranges (HI terminal)
DC Voltage:
– Measurement Range: 100.000 mV, 1.00000 V, 10.0000 V, 100.000 V,
– Speed: Slow, Medium, Fast
– Default Setting: Autoranging, Slow measurement speed
– Measurement Method: Sigma Delta A-to-D converter
– Input Impedance: >10 G selected range (0.1 V and 1 V only) or ~10 M all
– Input Protection: 1000 V on all ranges (HI terminal)
