FLUKE-1625產(chǎn)品概述
The Fluke 1625 is a distinctive earth ground testers that can perform all four types of earth ground measurement. Specifically, the Fluke 1625 testers are 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
3- and 4-Pole Fall of Potential — standard earth ground testing using two ground 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 Fluke 1625 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
