The Geo 30 Earth Ground Clamp simplifies ground loop testing and enables non-intrusive leakage current measurement. The HEME Geo 30 indicates and measures True RMS current flow from a few µA up to 30 A. The HI/LO function can be used to quickly evaluate the measured value by comparing against upper and lower limits and a recording function allows storage of measured values. The Geo 30 speeds and simplifies ground / earth testing for utility specialists and lightning protection installers.

• Ground loop resistance clamp measurement without any disconnection or additional ground rods
• Low level measurement of ground leakage current without disconnection for system troubleshooting
• Wide ac current measurement range up to 30 A with one instrument
• Rapid evaluation of continuity loop resistance by audible HI/LO alarm
• Easy to use, convenient, Display-HOLD function
• Time saving memory function for saving measured values and automatic recording
• Automatic self calibration ensures correct measurement every time

Measuring System
The clamp-on ground testing technique used by the HEME GEO 30 simplifies ground loop testing and enables non intrusive leakage current measurement. As a complement to common continuity and earth measurements performed with the: HANDY GEO and SATURN GEO Series, the HEME GEO 30 clamp-on ground tester offers the advantage of rapid earth testing in a completely safe way similar to the stakeless earth measurement available in the SATURN GEO X. This technique offers time saving and complete safety to the user. In addition the HEME GEO 30 will indicate and measure current flow from a few ìA up to 30 A. This sensitive TRMS current measurement is especially useful when it comes to measuring leakage currents flowing to earth. The HI/LO function automatically evaluates the measured value by comparing against upper and lower limits. The record function allows automatic storage of measured values. The compact and rugged design makes the HEME GEO 30 easy to use in small places and harsh environments, while the display HOLD and the continuity testing with an audible alarm function ensures convenience in use. The novel technique means that continuity testing can be completed without breaking the circuit.
