Stakeless Testing
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)

Fluke’s two-pole voltage and continuity testers are built to work the way you work. They give you the best combination of safety, ease-of-use and fast answers available anywhere.

How do we test our new and improved Two-Pole Voltage and Continuity Testers?

Two-pole voltage and continuity testers measure voltage, but just as important is when a two-pole tester tells you that there is NOT voltage present before working on any circuit. For you to rely on your two-pole tester, it has to be the most rugged and reliable tester you can find. That’s what Fluke’s redesigned two-pole testers give you.
Fluke knows the cable assembly is often where failures occur. The cable on any Two-Pole voltage and continuity tester is its weakest point- it is repeatedly bent, twisted, wrapped and put under constant strain. If the cable were to break, it could place you at an increased safety risk. Industry standards call for the cable to be tested to withstand a forty-five-degree bend, and still work after 5000 bend cycles. Fluke puts our testers through three times what the standard demands, flexing the cable over 150 degrees in each direction. This is why we can offer you our strongest voltage and continuity testers warranty ever.
Other useful features
• Dual insulated cable tested to 3x the required bend angle provides increased reliability and durability.
• Switchable load: avoid display of ghost voltages allowing you to draw more current from the circuit under test and avoid trip residual-current devices (RCDs)
• Backlit graduated scale and backlit indicators
• Built in electric torch for use in dark areas. (T110, T130, T150)
• Resistance testing to 1999 ohms. (T150)
• Audio on/off for testing in quiet areas. (T110, T130, T150)
• Improved probe docking for secure storage.
• Phase rotation indicator for 3-phase systems. (T110, T130, T150)
• Display hold freezes reading on display until your can view it comfortably. (T130, T150)
• Single-pole phase test offers fast identification of live conductors.
• Push-on probe tips, probe tip protector and storage accessory.
• Tip protector serves as an extra hand when opening UK electrical safety outlets.
• Low battery indicator.
