SPECIAL INSTALLATIONS TESTING, MAINTENANCE, TROUBLESHOOTING, AIRPORTS, RAILWAY, INDUSTRY, EVSE
There are many applications where test instruments as a standalone units are not sufficient enough to cover their needs. Those applications typically subject to special installations and are covered by external adapters. The reasons for the need of adapter could be:
- 3-phase mains connectors (3-phase active switch adapter);
- Combination of requirements from different special installations (EVSE);
- The need of higher power source, DC impedance testing, industrial RCD (Impedance adapters).
