FUNCTION DESCRIPTION
Input & Scaling Functions
(Option Code: AV)
Dual input types:
Voltage and Current Type are in one unit available in option. If the
customer specify the input coding for AV, the meter will be calibrated for
0~10V and 0~20mA in factory. The user can use in 0~10V or4(0)~20mA
by difference terminals connection(#11 & #13 for 0~10V or #12 & #13 for
4(0)~20mA) and programming in 【Ai.tYP】of【inPUt GroUP】.
Scaling function:
Setting the Lo.SC(Low scale) and Hi.SC(High scale) in【inPUt
GroUP】to relative input signal. Reverse scaling will be done too.
