Description
Order-Nr. 0590 7701
This clamp meter means you can cope in any application environment, no matter how tight. The movable pincer arm can be fully retracted into the instrument, so that you can for instance grab tightly packed cables in switching cabinets as if you were using a hook. You have never been able to measure as conveniently as this in tight spots.
The operation of the testo 770-1 clamp meter is also easier and more reliable than ever before. It automatically detects and selects AC/DC and other electrical parameters, such as resistance, continuity, diode and capacitance. In addition, you can also use it to measure the starting current. And the two-line display presents your readings clearly and distinctl.
Testo 770-1 Clamp Meter Key features
Built for maintenance, commissioning, and troubleshooting, 770-1 covers core ranges plus resistance, continuity, diode, capacitance, and frequency—reducing tool swaps on site.
- Measure faster with fewer steps: auto AC/DC + clear dual-line display.
- Clamp safely in tight cabinets: patented slide/hook jaw isolates one conductor.
- Capture starts/transients: inrush + True-RMS for accurate readings on non-linear loads.
- Everyday coverage: 400 A AC/DC, 600 V AC/DC, resistance to 40 MΩ, capacitance to 100 µF, frequency to 9.999 kHz.
- Pro-grade safety: CAT IV 600 V / CAT III 1000 V.
