Datasheet Testo 750-2 (EN) | Instruction Manual Testo 750-2 (EN)
The industrial voltage tester Testo 750-2 is a robust and innovative instrument engineered for reliable verification of electrical installations and grids. Featuring a patented all-round LED display with advanced fibre-optic technology, it delivers clear voltage indication from any physical angle. This model supports rapid single pole phase testing to instantly determine live conductors, alongside multi-point continuity testing and 3-phase rotating magnetic field testing. The integrated RC trigger function with load buttons provides vibration feedback during testing to safeguard against accidental triggering of residual current circuit breakers.
B2B Industrial Applications
- De-energization and Safety Checks: Verifying complete power breakdown on high-voltage distribution frames before field service.
- RCD Performance Testing: Deploying the RC trigger function under load to confirm correct threshold tripping of safety switches.
- Phase Rotation Verification: Determining power direction vectors via comprehensive rotating magnetic field testing on plant motor blocks.
