Auxiliary earth
resistance check

Robust steel madeearth spikes

If the auxiliary earth resistance is:
Too high at S(P) terminal*1 For precision measurement, auxiliary earth resistance should be 100Ω ±5% or less.
*2 At simplified measurement add ±0.10Ω to the specified accuracy.
*3 Accuracy within the auxiliary earth resistance: ±5%rdg±10dgt.

* Bluetooth® is the trademark or registered trademark of Bluetooth SIG.

Too high at H(C) terminal

Earth measurements are possible
up to 100kΩ* of auxiliary earth
spikes resistance.

Within allowable range (Green LED OK)* 20Ω range 10kΩ, 200Ω range 50kΩ,
2000Ω range 100kΩ.
