METRALINE RCD-CHECK RCD Testers
Meter that checks the characteristics of a GFCI (RCD).
In particular, it concerns the measurement of contact voltage, the turn-off and turn-off at RCD type A, AC, S and, more recently, the mixing frequency type F.

Features
Digital display, colored backlit OLED display
LED for electrical torch
Patented fixing the probe tips
Compact and robust - for harsh service conditions and laboratory use

Tests
Testing of residual current devices (RCDs)
Measurement of contact voltage without the draw of the switch. Here, the reference to nominal residual current contact voltage is measured with 1/3 of the rated fault current.
Trip test with nominal residual current, measure the operating time
Special tests for equipment and RCDs
Testing of equipment and GFCI circuits
with rising residual current and display the tripping current
Testing of RCDs I¿N = 10, 30, 100, 300 and 500 mA
Testing of RCDs with.
2.1 I¿N, I¿N 1, 2 I¿N, 5 I¿N to 100 mA nominal current)
Testing of RCDs with half-wave (pulsating DC) to determine the tripping time and tripping current
Testing of special GFCI breaker
S selective, type AC (not approved in Germany), Type A
Measurement of line voltage and fault loop impedance
