• Data taking at a step is over, the next step display appears. Time lapse display is also
reset and counts up from the beginning.

• When the last step is completed, data taken is stored in
memory. Several sec are required to complete string. → Stor
(Display)
• When completed, "End" is displayed. → End
(If data is to be retakes, press [ENT] key. The display returns to the status of (a).)
The above demonstrated the plateau characteristic taking operation including that for changing
setting contents.
Here the notable points in setting data are summarized. Permissible ranges for each setpoint are
as shown in Table 5.13.

When a setpoint exceeds the permissible range, “not" is displayed. Reset it by pressing [>] key.
By resetting, the display returns to the data value before change.
In addition, the starting voltage must be set to be larger than the stopping voltage and also the
setting width must be larger than 0.1 V.
Starting Voltage − 0.1 V > Stopping Voltage
These set data are checked the instant [ENT] key is pressed with "execution selection" display
set to ON. If the conditions are not met, an error message of "not" appears. The error message
is reset by pressing [>] key. By pressing [>] key, the display returns to "Go _ oF" display. Then,
change the voltage setpoint.
The operating procedure when taking plateau characteristic with the same setting contents as
the previous time is shown below.
(Example)
(a) Select function code “9" in <MAINT.> mode. → PLt_E
(b) On pressing [ENT] key, the starting voltage is displayed. → L00.00 V
(c) On pressing [ENT] key, the stopping voltage is displayed. → H-0.80 V
(d) On pressing [ENT] key, the number of steps is displayed. → P0008
(e) Pressing [ENT] key displays "Execution selection".
→ Go_oF
(f) Pressing [>] key displays "Executable". → Go_on
(g) On pressing [ENT] key, characteristic taking is executed. → 00.001
