NOTE
6-48 Applied Operation
■ Setup procedure for external resistance control
This procedure is common to CC, CR, CP, and CV modes. Follow this procedure for
modes other than CC mode.
• It is recommended that the external variable resistor connected to the PLZ-4W be
a wire wound resistor, metal film resistor, or multirotational potentiometer that is
resistant to temperature and aging. The residual resistance must be less than 50 
when set to the minimum resistance.
• Set the resistance to the minimum when using proportional control; set the resis-
tance to the maximum when using inverse proportional control.
• Use twisted wires for the signal wires. This can prevent disturbance from noise.
1. Check that the power is turned off.
2. Connect the external resistance.
Connect the external variable resistor across pins 1 and 3 of the J1 connector.
3. Turn on the power.
4. Check that the load is turned off.
Check that the LOAD LED is turned off. If the LED is illuminated, press the
LOAD key to cut off the current.
5. Set the operation mode and current value.
Press the MODE key to select the operation mode.
Press the RANGE key to set the current range. When also controlling the cur-
rent range externally, be sure to select H range on the panel.
6. Select the menu setup.
Press the MENU (SHIFT+SET/VSET) key.
The menu appears.
7. Select Configuration
Press the or
lighted on the menu. When highlighted, press the ENTER key.
8. Select External.
Press the or
the menu. When highlighted, press the ENTER key.
9. Select resistance control.
Press the CURSOR key to move the cursor (blinking) to the Control line.
To use proportional control, turn the rotary knob to select R.
To use inverse proportional control, turn the rotary knob to select Rinv.
10. Exit from the menu.
Press the MENU (SHIFT+SET/VSET) key.
The original screen displayed before entering menu setup appears.
11. Power cycle the PLZ-4W.
The menu settings are confirmed.
