4.4.8 Setup Function and Backup Memory
The PLZ-3WH series electronic load unit automatically saves and maintains the setup status immediately before a
power-off. You can also copy part or all of the set values listed below as setup values for backup purposes, so that the
load unit can be easily set under various different conditions.
Four sets of setup values can be saved as backup data when you use the built-in backup memories.
The built-in backup memories are maintained by built-in chargeable batteries. These batteries are charged while the
load unit is being turned on, and maintain the memory contents for about one month after turning off the power.
The setup values to be saved to the built-in backup memories are specified from the setup function menu.
The storable setup values and their defaults are as follows.
• Set configuration value (default at shipment from factory)
• Load power-on/power-off (off)
• ISET value (0 A)
• RSET value (maximum)
• VSET value (0 V)
• PSET value (maximum)
• CC/CR mode range (H)
• TrTf value (50 µ s)
• Soft start time setting (0.5 ms)
• CV on/off status (off)
• Contents of memories A, B, and C (above defaults are set for each operating mode)
To select the setup values you want to save, call the setup function menu. As saved values, you can specify all the
above setup values (ALL); all the setup values except for the contents of memories A, B, and C (SET); or the contents
of memories A, B, and C only (MEM). The setup function menu items and their contents are as follows (the operating
procedure is shown on the next page).
1: Initialize Setup Initializes all the setup values.
2: Store [ALL] Saves all the setup values to the backup memories.
3: Recall [ALL] Calls all the setup values from the backup memories.
4: Store [SET] Saves all the setup values, except for the contents of memories A, B, and C, to the backup
memories.
5: Recall [SET] Calls all the setup values, except for the contents of memories A, B, and C, from the backup
memories.
6: Store [MEM] Saves only the contents of memories A, B, and C to the backup memories.
7: Recall [MEM] Calls only the contents of memories A, B, and C from the backup memories.
NOTE
After "1: Initialize Setup" is executed, the menu is automatically closed. To close the menu when other
menu items have been executed, press the [ESC] key after completing the relevant operation.
