Note

The applied voltage changes in the direction of increasing negative voltage.

The number of diffusion current samples is “the number of steps plus one”.

Applied voltage at each step are computed automatically when executed.

Figure 5.4 Example of Taking Plateau Characteristics
The key operation procedure for <taking plateau characteristic> is as follows:
(Example)
(a) Select function code “9" in <MAINT.> mode. → PLt_E
(Display)
(b) On pressing [ENT] key, the starting voltage is displayed. → L00.00 V
(c) To change the setting, press [>] key.
→ L 0 0.00 V
(If no setting change is required, operate from step (e).)
(Leftmost digit flashes.)
(d) Select a digit using [>] key and set the numeric value
using [Λ] and [>] keys. → L00. 1 0 V
Pressing [ENT] key now fixes the numeric value.
(Last set digit flashes.)
(e) Press [ENT] key to display the stopping voltage. → H-1.00 V
(f) To change the setting, press [>] key. → H - 1.00 V
(If no setpoint change is required, start from step (h).)
(Thenegative sign flashes.)
(g) Select a digit using [>] key and set the numeric value
using [Λ] and [>] keys. → H-0. 8 0 V
By next pressing [ENT] key, the numeric value is fixed.
(Last set digit flashes.)
(h) On pressing [ENT] key, the number of steps is displayed. → P0010
(i) To change the setting, press [>] key.
→ P 0010
(If no setpoint change is required, start from step (k).)
(Leftmost numeral flashes.)
(j) Select a digit using [>] key and set the numeric value
using [Λ] and [>] keys. → P000 8
Pressing [ENT] key now fixes the numeric value.
(Last set digit flashes.)
(k) Pressing [ENT] key displays "Execution selection". → Go_oF
If each setpoint is to be reconfirmed, press [ENT] key.
The display returns to (b) starting voltage display.
(l) If the displayed item is to be executed, press [>] key. → Go_on
(m) On pressing [ENT] key, characteristic taking is executed.
