Ranging - Agilent Technologies L34410A User Manual

Ranging

Applies to all measurements except continuity and diode test, which use a
fixed range. Temperature measurements always use autoranging.
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 ac
• For temperature measurements, the multimeter uses autoranging, as
• For continuity tests, the multimeter range is fixed at 1 kΩ . For diode tests
• Front Panel Operation: For applicable measurement functions, the ranging
