Figure 6.5 Example of Plateau Characteristic Collection
• Selection of plateau characteristic collection/data readout
To collect plateau characteristic data, select message *MEAS and press the
YES
key.
Pressing the
NO
key with *MEAS displayed causes the FC400G to enter *READ. Pressing
the
YES
key again calls up the previously collected data in turn.
• Setting Initial Applied-voltage (when *MEAS is selected)
Set initial applied-voltage *INI V in the range of -1.00 to 1.00 V. This parameter is set to 1.00 V at
factory shipment.
• Setting Step Applied-voltage (when *MEAS is selected)
Set step applied-voltage *STP V in the range of -1.00 to 1.00 V. This parameter is set to -0.20 V
at factory shipment.
• Setting Step count (when *MEAS is selected)
Set step count *STP NO in the range of 1 to 20 steps. This parameter is set to step 10 at factory
shipment.
After completion of setting of the noted parameters, *START appears on the LCD.
Then, press the
YES
key. This starts plateau characteristic collection.
