Fluke 1625-2 Advanced GEO Earth Tester Kit

Fluke 1625-2 Advanced GEO Earth Tester Kit
FOR EACH TEST, THE TESTERS INFORM YOU WHICH STAKES OR CLAMPS NEED TO BE CONNECTED AND THE LARGE ROTARY SWITCH CAN BE USED EVEN WITH A GLOVED HAND

INSTRUMENT FEATURES
The Fluke 1625-2 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.
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.

Fluke 1625-2 GEO Earth Tester Kit Features
Automatic Frequency Control (AFC): Identifies existing interference.

Fluke 1630 Earth Ground Clamp

Fluke 1630 Earth Ground Clamp
THE RUGGED AND COMPACT DESIGN MAKES THE FLUKE 1630 EASY TO USE IN SMALL PLACES AND HARSH ENVIRONMENTS

INSTRUMENT FEATURES
The Fluke 1630 Earth Ground Clamp is a hand-held battery-operated clamp that measures the ground resistance of a ground rod without using auxiliary ground rods. The 1630 can be used in multi-grounded systems without disconnecting the ground under test.

Kyoritsu 4300 Simplified Earth Tester

KYORITSU 4300 Simplified Earth Tester
KEW 4300 is simplified earth resistance tester (based on 2-pole method) that can be used for various distribution lines and electrical appliances and it also can measure AC/DC voltage. (As for AC Voltages, true rms values can be obtained.)

• 200/2000Ω (2 ranges): auto-ranging.
• Warning buzzer triggered at 100Ω or less.
• LED lights up when a large earth voltage is detected.
• Live circuit warning when 30V or higher voltage is detected. (KEW 4300 detects voltage even when measuring resistances.)
• LED light for illuminating measurement points. (It turns on/off automatically in relation to the ambient brightness.)
• Small test current (max 2mA) not triggering RCD.

Earth resistance ranges	200.0/2000Ω (Auto ranging) ±3%rdg±5dgt
Voltage ranges	AC: 5.0 ~ 300.0V (45 ~ 65Hz)±1%rdg±4dgt DC: ±5.0 ~ 300.0V±1%rdg±8dgt
