Selecting a Range
60 U3606B User’s Guide
NOTE
• Autoranging is selected at default factory power-on and after a remote
reset.
• Manual ranging — If the input signal is greater than can be measured
on the selected range, the multimeter provides these overload
indications: “+/– OL” from the front panel or “±9.9E+37” from the
remote interface.
• For frequency, pulse width, and duty cycle measurements, ranging
applies to the input voltage or input current of the signal, not its
frequency.
• The range is fixed for diode (1 V
dc
range) tests.
• The U3606B remembers the selected ranging method (auto or manual)
and the selected manual range for each measurement function.
• Autorange thresholds — The U3606B shifts ranges as follows:
Down range at < 10% of current range
Up range at > 120% of current range
