Description
R1+R2 ZS / ZE CALCULATIONS
Calculate the earth loop impedance (Zs) from the R1+R2 and Ze values or calculate the R1+R2 value from the Zs / Ze values.
Calculating R1+R2 is a very simple equation of R1+R2 = Zs - Ze, however if you have many calculations to do that is where the R1+R2 calculator can help to save time.
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!

Simple, slightly faster than a calculator time is in short supply nowadays.
Saves Time
R1+R2 Zs CALCULATIONS
If you have multiple R1+R2 or Zs calculations to complete this app can help by saving time, for example, when calculating R1+R1 enter your Ze and Zs values and calculate, then for the next calculation just update the Zs value and calculate again.
- Quick n Easy
- Saves Time
- Calculate Zs from R1+R2 and Ze
- Calculate R1+R2 from Zs and Ze
Enter any two values to calculate the remaining value.
Calculate R1+R2
R1+R2 FROM Zs
To calculate R1+R2 from Zs enter your measured Zs and measured Ze values, then hit “Calculate”.
Calculating R1+R2 or Zs is a very simple calculation but if you have multiple calculations to do then that’s where this app can speed up the process.
Calculates:
- R1+R2.
- Zs (Earth Loop Impedance).
- Ze (External Earth Loop Impedance) – not recommended to calculate.
Enter any two values to calculate the other!
To Calculate R1+R2:
R1+R2 = Zs – Ze
Calculate Zs
Zs FROM R1+R2
To calculate Zs enter your measured Zs and measured R1+R1 values.
To Calculate Zs:
Zs = Ze + R1+R2
Max Zs
For maximum Zs values see our Max Zs Values App.
Calculate Ze
Ze CALCULATIONS
Note: Ze should not be calculated, the Ze should only be obtained by direct measurement with the appropriate test equipment and by following the approved procedures.
