Product Description

Automatic Frequency Controlearth ground resistance tester ST2308

 

ST2308 is distinctive earth ground tester that can perform all four types of earth ground measurement. Specifically, the ST2308 tester is able to measure earth ground loop resistances using only clamps - called Stakeless testing. This method doesn't require the use of earth ground stakes or the disconnection of ground rods.

Testing Methods

2 Pole, 3 Pole and 4 Pole Fall of Potential - standard earth ground testing using two grounds stakes

Selective testing - without disconnecting ground rods, a technician can measure ground resistance using a combination of stakes and a clamp.

Stakeless testing - innovative solution using only clamps, instead of ground stakes, to measure earth ground loop resistance.

The ST2308 offers these advanced features

Automatic Frequency Control (AFC) - identifies existing interference and chooses a measurement frequency to minimize its effect, providing a more accurate earth ground value.

R* measurement - calculates earth ground impedance at 55 Hz to more accurately reflect the earth ground resistance that a fault-to-earth ground would see.

Adjustable limits - for quick test result verification.

One-button measurement concept

2- pole, 3-pole and 3-pole earth ground measurement and soil resistivity testing

Selective testing, no disconnection of ground conductor (1 clamp)

Stakeless testing, quick ground loop testing (2 clamps)

Measuring AC current to 20A
