3.3.4 Electric current 1 ... 20 mA correction
Since the setting and principle of correction of 4 mA and 20 mA of current are same, so
4 mA setting and correction are taken as an example here.
Menu 3.3.1 Electric current 1 ... 4 mA setting
The user can freely set the current 1 ... 4 mA setting value. After pressing Enter, the
system will automatically save the settings.
Menu 3.3.2 Electric current 1 ... 20 mA setting
The user can freely set the current 1 ... 20 mA setting value. After pressing Enter,
the system will automatically save the settings.
Note
：
The conductivity value and current value set in 4 ... 20 mA correspond to each
other, and the calculation formula is
：
outMa
＝
(20.00 ... 4.00) / (endMa
－
startMa) *(hold
－
startMa)
＋
4.00
outMa is the value of output current
startMa is conductivity value set by 4 mA
endMa is conductivity value set by 20 mA
Hold is present measured value
For example
：
4 mA is set to 0.00
μS/cm, 20 mA is set to 20.00 μS/cm, and when the conductivity
value is 10.00
μS/cm, the current output is 12.00 mA.
