1630 Earth Ground
Clamp Meter
The Fluke 1630 earth ground clamp
meter simplifies ground loop testing and
enables non-intrusive leakage current
measurement. The ground loop testing is
also known as “stakeless” earth ground
testing. To carry out the measurement
there is no need for placing earth stakes
and disconnecting the earth system
from the electrical installation. The Fluke
1630 combines the two current clamps
needed to perform the stakeless ground
loop test in one compact and easy to use
instrument.
• Ground loop resistance testing without
any disconnection or additional earth
stakes
• Earth ground leakage current
measurement for system
troubleshooting
• True RMS AC current measurement
range up to 30 A
