can also be used as a workshop test panel per DIN VDE 0104.
For testing electrical safety of single and 3-phase electrical equipment:
The METRATESTER 5-3P performs the following tests in accordance with the
- Protective conductor resistance
- Insulation resistance
- Earth leakage current
- Residual current
- Contact current
- Protective conductor current
The METRATESTER 5+3P test case complies with “guidelines for equipment
required for electrical installation operations” issued by the Federal
Committee for Electrical Installations, ZVEH, WFE and electrical power utilities.
- Mains connection
The test case can either be connected to an earthing contact outlet with
the two included power cables, or to a 16 A CEE mains outlet.
- Test types
DIN VDE tests without mains operation: protective conductor resistance,
insulation resistance, equivalent leakage current. DIN VDE with mains
operation at all single and 3-phase devices: differential current, contact
current. Function tests with measurement of current consumption and voltage
in phases L1, L2 and L3. Protective conductor measurement is performed
correctly in accordance with DIN VDE 0104.
- Contact surface for finger contact
Protective conductor potential can be tested by means of a contact
surface for finger contact. The PE signal lamp lights up if a potential
difference of more than 100 V is detected between the contact surface and
the protective contact at the mains plug.
- Differential current measurement
Measurement of differential current complies with regulations for
periodic testing in accordance with DIN VDE 0702.
- Convenient testing
All safety and function tests are performed by simply switching mains
voltage, or the individual phases, to the devices under test.
- Display functions
All measured values are clearly displayed at a large digital display.
Exceeded limit values are also indicated optically, and in some cases
acoustically as well.
- Rugged case design
The test case consists of an aluminum shell and a removable, lockable
lid. Ample space is provided for the included connection adapters and
