Changing the unit string of custom unit

The following is an example to show how to change the unit string from AAA/BBB to XXX/ZZZ.

Switch operation	Display example		Description

	B4: CUSTOM UNIT	Select B4: CUSTOM UNIT from the setting item selection
		menu.
	AAA/BBB
		The currently set unit appears.


	B4: CUSTOM UNIT	The cursor appears.
		Press	further to move the cursor to the desired digit to
	AAA/BBB
		change.


	B4: CUSTOM UNIT	Change the character of the digit. (Note 1)
	XAA/BBB	To change other digit, press		to move the cursor to that digit

↓and change the character there. Repeat this operation until

	XXX/ZZZ	XXX/ZZZ appears on the display.

		The display blinks and the set value is displayed for
	B4: CUSTOM UNIT	confirmation.
		Press	MENU/ENT	again to write the data. Then the cursor
	XXX/ZZZ
		disappears and the display returns to the condition that the set

		value is displayed.

B4: CUSTOM UNIT

Returns to the menu of setting item selection.
