Instantaneous Scaling 20 to 20000
Totalizer
Totalizing constant 20 to 99999(Totalized value for 1 hour during 100 ％ input)
Display accuracy Totalizer ±（ 0.2 ％＋ 1digit ） of the rated value
Rated value ： Theoretical value to be totalized when 100% input
continues continuously
Instantaneous
± (0.2 ％ of SPAN + 1digit) at 23 ℃± 5 ℃ 45 to 75 ％ RH
Synchronized totalize
pulse output
（ P.O ）
It is isolated from input.
Output signal ： Open collector (NPN),
Output capacity ： DC30V 200mA, Leakage current ： Less than 0.1mA
Reset Reset the totalized count to 0 (zero) or initial totalize value from the RESET key on
the front panel or from the RESET terminal on the rear terminal board. The
frequency division stage of the PO output is also cleared.
No voltage contact or open collector
