Have multiple R1+R2 calculations to complete? It’s faster with the app.

Easily calculate the earth loop impedance (Zs) from the R1+R2 and Ze values or calculate the R1+R2 value from the Zs / Ze values.
A handy app for checking & verifying measured R1+R2 values or for calculating a value (Zs, R1+R2) from the other two known values.
While this app can calculate Ze, Ze values should only be obtained by direct measurement or by inquiry, not calculated. It is best practice to directly measure R1+R2 and Zs values.
- Zs, Ze and R1+R2 calculations with instant results!
