４－１． Setting method
Various settings of electronic counter are configured by the electronic counter itself (note that items
which can be set are limited) or the dedicated setting device (Windows software).
Please set in the following procedure when it is set by electronic counter itself.
Setting mode ・・・・・・・・・・ Display “ＳＥｔ ｙ ｏｒ ｎ” when ＳＷ１ and ＧＮＤ are short for morethan 5 seconds.
ＳＷ２ and ＧＮＤ are short when the setting is changed.
ＳＷ１ and ＧＮＤ are short when there is no change.
Decimal point・・・・・・・・・・ ＳＷ１ and ＧＮＤ are short in case of any change.
ＳＷ２ and ＧＮＤ are short in case of decision.
Total integrated value・・・・ ＳＷ１ and ＧＮＤ are short in case of any change.
ＳＷ２ and ＧＮＤ are short in case of decision.
Pulse rate of input 1 ・・・・ ＳＷ１ and ＧＮＤ are short in case of any change.
ＳＷ２ and ＧＮＤ are short in case of decision.
Pulse rate of input 2 ・・・・ ＳＷ１ and ＧＮＤ are short in case of any change.
ＳＷ２ and ＧＮＤ are short in case of decision.
Pulse rate of output ・・・・

End

ＳＷ１ and ＧＮＤ are short in case of any change.
ＳＷ２ and ＧＮＤ are short in case of decision.

・・・・It becomes reset mode when magnet is touched on the reset switch of counter for more than 5seconds. (As regards reset switch, please refer to “Instruction manual 2. Name of parts”. Resetswitch is invisible from outside.)
Liquid display will be shown “CLEAr” on the counter and integrated value will be reset to 0.
Please do not touch with the magnet while at the reset mode because integrated value will bereset automatically.
Only integrated value will be reset.
