PH-6800

Note: When the relay drives the inductive load, please install an intermediate relay to prevent the contact from being broken down and ionized by the inductive back EMF and burning the contact.

4-20mA current output formula

1.PH Current output formula:
Factory setting define output current value is :0 pH is corresponding value of 4 mA; 14 pH is corresponding value of 20 mA.
I = ( D - 4 mA corresponding value)× ( 16 / (20 mA corresponding value- 4 mA corresponding value) ) + 4.00
I = ( D - 0 )× ( 16 / 14 ) + 4.00
Note: I is output current value 4 mA≤I≤20 mA
D is pH value displayed by the instrument 0.00pH≤D≤14.00pH

2.Formula of ORP current output:
Factory setting define the output current is :-2000mV is corresponding
value of 4 mA; +2000mV is corresponding value of 20 mA.
I = ( D - 4 mA corresponding value )× ( 16 / (20 mA corresponding value - 4 mA corresponding value) ) + 4.00
I = ( D – (-2000) )× ( 16 / (+2000 – (-2000)) ) + 4.00
I = ( D + 2000 )× ( 16 / 4000) ) + 4.00
Note:I is output current value 4 mA≤I≤20 mA
D is ORP value displayed by the instrument -2000mV≤D≤+2000mV
