Chapter 3 Operation Overview
Auto setup works only with the Memory function.
By applying an input signal, the timebase, measurement range and zero position
of the input waveform are set automatically. The range is determined for each
channel that has its waveform enabled [On] for measuring. The timebase is
automatically set so that 1 to 2.5 cycles are recorded within 25 divisions on the
lowest-numbered channel being used.
Auto setup is not available with some input modules and measurement modes.
3.3.5 Automatic Range Setting (Auto-Ranging Func-
tion)
Input modules and measurement modes not supported by auto setup:
• The [Temp] mode of the Model 8937 Voltage/Temp Unit
• Model 8939 Strain Unit
• Model 8960 Strain Unit
• [Count], [Duty] and [50/60 Hz] (mains frequency measurement) modes of the
Model 8940 F/V Unit
• [Charge] and [Preamp] modes of the Model 8947 Charge Unit
• Model 8958 16-Ch Scanner Unit
• Auto setup does not work correctly with signal frequencies below 3 Hz, so
manual setting is necessary.
Before performing auto setup
• Before auto setup, establish the actual measurement situation (with the signal
applied to the instrument), such as by connecting to the measurement object.
• During auto setup, a trigger signal is output from the TRIG OUT
/CAL external I/
O terminal. Keep this in mind if using this terminal during auto setup.
1 Press the DISP key to display the Waveform screen.
2 Press the FUNCTION MODE key to enable the FN mode.
3 Press the F4 [Auto Setup] key. A confirmation dialog appears.
4 Press the F1 [OK] key.
Perform auto setup with the existing input signal, and start waveform
recording.
Recording continues until you press the STOP key.
