Gossen Metrawatt M507B MetraLine RCD Test Instrument

M507B Includes Only:

• 1 Test instrument with mobile test probe and
• 4 batteries (AAA)
• 1 Pouch
• 1 Condensed operating instructions
• 1 CD-ROM with operating instructions in languages
• 1 Factory calibration certificate

Features:

• Digital display, backlit color OLED display
• LED for measurement point illumination
• Patented test probe retainer
• Compact and rugged - for service calls under harsh conditions and laboratory use
• Testing of residual current devices (RCCBs)
• Measurement of touch voltage without tripping the RCCB. Touch voltage is measured with reference to the Nominal residual current using 1/3 of the Nominal residual current value.
• Tripping test with Nominal residual current, measurement of time to trip
• Special tests for systems and RCDs
• Testing of systems and RCDs with rising residual current including an indication of tripping current
• Testing of RCDs, IΔN = 10, 30, 100, 300, and 500 mA
• Testing of RCCBs with 1/2ΔN, 1ΔN, 2ΔN, 5ΔN up to100 mA Nominal current
• Testing of RCDs with half-waves (pulsating direct current) for determining the time to trip and tripping current
• Testing of special RCDs
• Selective, type AC, type A
• Measurement of line voltage and fault loop impedance

Measuring instrument for testing the characteristics of RCCBs. In particular, this involves the measurement of touch voltage, breaking time and breaking current for type A, AC, and S RCCBs, as well as type F mixed frequency RCDs as of recently.
