The Agam earth tester, AET 23 is capable of performing measurements of both earth resistance in ohms and also calculates AC earth voltage from 0-200V.Earth resistance testing can be performed across three ranges: 0-20 Ohms , 0-200 Ohms and 0-2000 Ohms.

Earth Resistance Ranges
0-20 Ohms: -+ (2%+10)
0-200 Ohms: -+ (2%+3)
0-2000 Ohms: -+ (2%+3)
AC Earth Voltage 0-200V: -+ (1%+4)
Display Count: 2000

Very simple to use, simply make the connections necessary turn the rotary dial to the procedure you want and hit the testing button.To make testing easier the AET 23 is equipped with limited built-in memory that can store up to 20 testing results. A data hold function is also available that will temporarily store the last value taken but will not store the result in memory.This earth resistance tester is also suitable for use on both 50Hz and 60Hz frequencies, comes with a 2000 count backlit LCD display, is manual ranging and includes double insulation protection to ensure safety.

The Fluke 1623-2 earth ground tester is able to measure earth ground loop resistances using only clamps. With this test method, two clamps are placed around the earth ground rod and each are connected to the tester. No earth ground stakes are used at all. A known, fixed voltage is induced by one clamp and the current is measured using the second clamp. Then the tester automatically determines the resistance of the earth ground rod. This test method only works if a bonded earth ground system exists for the building or structure under test, but most are. If there is only one path to ground, like at many residential applications, the Stakeless method will not provide an acceptable value and the Fall-of-Potential test method must be used.

With Stakeless testing, the earth ground rod does not need to be disconnected - leaving the bonded earth ground system intact during test. Gone are the days of spending time placing and connecting stakes for each earth ground rod on your system - a major time saver. You can also perform earth ground tests in places you’ve not considered before: inside buildings, power pylons, or anywhere you don’t have access to soil.

The Most Complete Tester

The Fluke 1623-2 is a unique earth ground tester that can perform all four types of earth ground measurement.

• 3- and 4-Pole Fall-of-Potential (using stakes)
• 4-Pole Soil Resistivity Testing (using stakes)
• Selective Testing (using 1 clamp and stakes)
• Stakeless Testing (using 2 clamps only)

• Test the grounding components of equipment in hard-to-reach spaces, including areas that are indoors or fully paved and do not permit driving auxiliary test stakes.
• AC Leakage Current Measurement: Identify AC leakage without disconnecting your earth ground stake from the grounding system
