Datasheet Testo 760-3 (EN) | Instruction Manual Testo 760-3 (EN)
The high-performance digital multimeter Testo 760-3 is the premier multitasker engineered for demanding heavy-duty industrial applications. Replacing traditional rotary dials with modern, backlit function keys, it features automatic measurement parameter detection via input socket assignment to completely rule out hazardous configuration errors. With an expanded voltage range up to 1000 V, a large frequency limit of 60 MHz, and capacitance capabilities up to 60000 microF, this true root mean square (TRMS) instrument incorporates an integrated low-pass filter to secure stable and precise troubleshooting measurements on complex inverter-controlled machinery and variable frequency drive motor setups.
B2B Industrial Applications
- Heavy Plant Troubleshooting: Executing safe electrical diagnostics on main distribution paths and high-capacity switchgear layouts up to 1000 V.
- Variable Frequency Drive Diagnostics: Implementing the built-in low-pass filter to damp harmonic disturbance on inverter-fed production motors.
- Subassembly Electrical Screening: High-accuracy determination of massive capacitance baselines and ultra-high frequency variables on industrial power filters.
