SYCAMORE, IL, August 14, 2009 -- When the grounding system of a cellular tower or a data center falters, networks outages can occur that inconvenience customers, shut down business operations, and endanger sensitive electronics. To avoid these problems, ongoing verification of the grounding system is required.
One of the easiest ways to troubleshoot a grounding system is the IDEAL 61-920 Ground Resistance Clamp Meter with auto-ranging. Its simple operation eliminates the need for leads, auxiliary rods, spacing provisions, or disconnecting of ground rods, as is necessary with traditional measuring techniques. Instead, the 61-920's jaws clamp around a ground rod for direct reading of ground resistance from 0.01 to 1200 Ohms, and for the direct measurement of ground leakage current up to 30 Amps. True RMS accurately measures AC current even with distorted waveforms due to harmonics.
"Our ground resistance clamp meter tests not only the rod but also the integrity of the bonds in the grounding system," said Dave Skowronski , Senior Product Manager for IDEAL. "It does no good to have a 5 ohm ground rod with a 80 ohm path leading to it. Testing with our clamp will show the user the true performance of their system, not just the rod."
The 61-920 features an oversized clamp to accommodate cables or rods up to 1.25-inches (32mm). In addition, it helps users achieve higher levels of productivity thanks to its large memory capacity for saving records, a data hold function for capturing readings, plus a powerful backlit LCD that can be read in dimly lit areas. There is also a continuity buzzer that issues an audible warning to the user when the measurement result is 10 Ohms or less, along with a Noise Check that senses current on the ground electrode or ground wire and displays "NOISE" on the LCD.
Rugged and dependable, the 61- 920 brings maximum value to the end-user. It is safety rated to CAT III 300V and backed by the IDEAL Two-Year Warranty.
The IDEAL 920 Series Ground Resistance Clamp Meter is now shipping with an MSRP of $1856 (U.S.).
