Test and measuring equipment

for testing single- and three-phase machines, welding machines, switchgears, cables, cable extensions, PRCDs, electrical installations, etc.

We develop and produce test instruments that perform all required safety tests on various machines in accordance with the EN 60204-1 standard, switchgears in accordance with the EN 61439-1 standard, welding machines in accordance with the EN 60974-4 standard as well as on many other test objects like cables, cable extensions, PRCDs, transformers, etc.

Depending on client specific requirements or particular market demands we develop and implement complete hardware and software solutions with diverse measurements inside each instrument’s system.

The following parameters can be measured by our products (selection of below parameters depends on type of test instrument):

  • Visual inspection.
  • Protective bonding resistance RPE using the two- or four-wire test method, safety test voltage 4 … 24 V AC and test current 0.2 A, 10 A or 25 A AC.
  • Protective bonding resistance RPE using the clamp method combined with the two- or four-wire method, safety test voltage 4 … 24 V AC and test current 0.2 A, 10 A or 25 A AC.
  • Insulation resistance RINS, test voltage 50 … 1000 V DC.
  • HV dielectric test, test voltage 250 … 5100 V AC, current capacity up to 110 mA.
  • Full RCD test, RCD types A, AC and B, characteristics G (general), S (selective) and D (delayed).
  • Full PRCD test according to the producer’s instructions.
  • Full cable and cable extension test.
  • Impedance of protective loop ZLOOP or active loop ZLINE and calculation of prospective short-circuit current IPSC.
  • Voltage drop in electrical installation.
  • Total earth resistance RA in TT systems using half of the nominal differential current of the used RCD device without tripping out the RCD.
  • Residual voltage URES on mains terminals using the two-wire method or inside the machine being tested using the two- or four-wire method.
  • Apparent power S, active power P, reactive power Q, differential current IPE, load current IL, phase and phase-phase voltages, cos(phi) and power factor PF.
  • Phase rotation.
  • Differential current IPE and load current IL by using the clamp method.
  • AUTO tests (combination of above measurements).
  • Possible testing of above parameters on three-phase machines, switchgears, welding machines, cables, cable extensions, etc.
  • Possible use of barcode reader.
  • Possible use of printer.

Important features that have been implemented:

  • Easy operation using the rotary switch, hard keys in combination with soft ones on a touch screen.
  • HELP screens available.
  • Automatic start function for protective bonding resistance measurement allows both hands to be used on measured objects that are difficult to access.
  • Compensation of test lead resistance for protective bonding resistance measurement and impedance measurement.
  • Calculation of limits for protective bonding resistance.
  • TRMS measurements.
  • The operation system WINDOWS EMBEDDED COMPACT 7 supports all measurements and operations.
  • Data memory for over 1,000 measurement results.
  • Integrated interface (USB 2.0) for transfer of measurement results to PC.
  • Separate multiple interfaces (USB 2.0) for connection of optional USB barcode reader, USB keyboard, USB memory stick or USB printer.
  • Bluetooth communication.
  • Color TFT touch screen LC-display for measurement values, limit values and test parameters.
  • Compact plastic housing with accessory bag.
  • Quick connection diagrams and limit values under the instrument’s cover.
  • Limit values adjustable through the whole measurement ranges in all functions.
  • Complete test accessories included.
  • Remote START/STOP and SAVE function.
  • Visual and acoustic warnings in case limit value is exceeded.
  • Real time clock for documentation of test results.
  • Single or continuous measurements.
  • Multiple languages can be chosen (English, German, Italian, French, Spanish, etc.).
  • Programmable AUTO test procedures.
