Ranging - Agilent Technologies 34410A User Manual

Ranging

This feature applies to voltage, current, resistance, capacitance and
frequency/period measurements only.
You can let the multimeter automatically select the range using
autoranging, or you can select a fixed range using manual ranging.
Autoranging is convenient because the multimeter automatically selects the
appropriate range for sensing and displaying each measurement. However,
manual ranging results in better performance, since the multimeter does
not have to determine which range to use for each measurement.
• Autorange thresholds – The multimeter will shift range as follows:
• Ranging is local to the selected function; the multimeter remembers the
• For frequency and period measurements, the selected range is for the
• For temperature measurements, the multimeter uses auto ranging,
• For continuity tests, the multimeter range is fixed at 1 kW, and for
• Front Panel Operation: For applicable measurement functions, the ranging
