Datasheet Testo 770-2 (EN) | Instruction Manual Testo 770-2 (EN)
The professional clamp meter Testo 770-2 is optimized for precise electrical diagnostics on closely bundled conductors within dense control blocks. Alongside the advanced features of the 770 series, it incorporates a dedicated microamp range (0.1 to 400.0 microA) via measuring cables and a plug-in temperature adapter for Type K thermocouples. The innovative retractable pincer arm allows users to separate individual wires smoothly in tight environments. Operating with full automation, it identifies and triggers AC/DC current, resistance, continuity, diode, and capacitance parameters while logging high-accuracy motor starting current profiles.
B2B Industrial Applications
- Burner Control Auditing: Utilizing the specialized microamp range to test ionization current fields on commercial boiler systems.
- Electric Motor Maintenance: Monitoring dynamic peak load variations and electrical starting current metrics during equipment startup.
- HVAC Control Panel Inspections: Combined testing of circuit board capacitance, line resistance, and thermal parameters via the temperature adapter.
