Measuring instrument which checks the qualities of a FI switch.
It is all about the measuring of the contact voltage in particular, determing time and tripping current of RCD types A, AC, S and F.
Features
Digital display, backlit color OLED display
LED for measurement point illumination
Patented means of securing the test probes
Compact and rugged - for service calls and laboratory use
Testing features
Testing of residual current devices (RCDs)
Measurement of touch voltage without tripping the RCCB.
Contact voltage is measured with reference to nominal residual current using 1/3 of the nominal residual current value.
Tripping test with nom. residual current, time to trip measurement
Special tests for equipment and RCDs
Testing of equipment and RCDs with rising residual current including indication of tripping current
Testing of RCDs, IΔN = 10, 30, 100, 300 and 500 mA
Testing RCDs with 1/2 IΔN, 1 IΔN, 2 IΔN, 5 IΔN up 100 mA nominal current)
Testing RCDs with half-waves (pulsating direct current) for determining time to trip and tripping current
Testing of special RCDs
selective S, type AC, type A
Measurement of line voltage and fault loop impedance
