• The ETCR2100C+ model is designed for the evaluation of resistance measurement on earth probes with ground loop method without the disconnection of parts of plants under test.
• This type of measurement carried out by the instrument can be used for evaluation of single rods’ resistances within an earth installation assuming they do not affect each other.
• The inner part of the instrument is made of 2 toroids one for current and one for voltage.
• The voltage toroid generates a potential (E) on the loop during resistance measurement.
• A current (I) is consequently generated on the loop and is measured by the current jaws.
• Based on the value of parameters E and I the instrument displays the resistance value R calculated as their ratio.
• The ETCR2100C+ clamp also performs AC current up to 20A and leakage current with 0.1mA resolution and the setting of alarm thresholds on measurements is possible.
• The instrument is compliance with IEC/EN61010-1, CAT III 150V and is ideal for simple measurements both in domestic and industrial environments.
