With Portuguese user interface Earthing resistance measurement in 5 ranges up to 50 kOhm Voltage measurement 10 ... 250 V Frequency measurement 45 ... 200 Hz

Battery operated tester for the meas urement of ground resistance meets international standards for performing such tests. This instrument allows measurement of soil resistivity and ohmic resistance by means of the ammeter-voltmeter test method.\

Applications

---

The GEOHM C is a compact instrument for the measurement of ground resistance in electrical systems in accordance with:

• DIN VDE 0100
  • Installation of power systems with nominal voltages of up to 1000 V
• DIN VDE 0141
  • Grounding in AC systems with nominal voltages of greater than 1 kV
• DIN VDE 0800
  • Installation and operation of telecommunications systems including data processing systems: equipotential bonding and grounding

Testing of lightning protection systems in accordance with DIN VDE 0185.

The instrument is also capable of determining soil resistivity which is essential in calculating dimensions for grounding systems. It can thus be taken advantage of for simple, geological surveys, and for the planning of grounding systems.

Beyond this, ohmic resistance can be measured at both solid and liquid conductors, as well as internal resistance at conductive elements, as long as these are capacitance and induction-free.

Special Functions

---

• Hold function: The measurement value is frozen at the display after the measurement key is released.
• Storage of measurement values to memory
• Data interface for the transmission of measurement values and for software updates
• Convenient report generating software, can be expanded into a comprehensive database

Signal Lamps

---

The instrument automatically recognizes errors which occur during measurement, and signals them with four LEDs as shown in the table below.
