The SECUTEST 21F test panel has been designed for integration into test benches at service centers for electrical equipment. It is laid out for the measurement and testing of electrical devices after the performance of repairs or modifications in accordance with VDE 0701, as well as periodic testing per DIN VDE 0702.

The test panel is of wall mount design. The mains switch is equipped with undervoltage release and a locking mechanism.

Load currents of up to 25 A and line voltages of up to 500 V can be measured.

Adherence to DIN VDE 0404 assures accurate measurement of protective conductors.

According to these regulations, protective conductor resistance, insulation resistance and equivalent leakage current must be measured, and testing must be conducted for the absence of voltage at user accessible conductive parts at data processing equipment and office machines.

The measurement of operating voltage and current consumption at devices under test, as well as testing for conductor continuity, represent further applications for the substantiation of correct functioning of electrical equipment. Beyond this, the protective conductor at the mains connection can be tested for the absence of voltage and line voltage can be measured.
