The innovative grab mechanism makes the testo 770-2 the perfect clamp meter for non-contact measurements on tightly packed cables with a small diameter. In addition to the standard functions of the testo 770-1 clamp meter, it also offers a temperature adapter and measures current in the µA range. Measuring range- Temperature: -20 to +500 °C Voltage: 1.0 to 600.0 V(AC/DC) Current: 0.1 to 400.0 A (clamp), 0.1 to 400.0 µA (measuring cables)(AC/DC) Resistance: 0.1 to 40.00 MOhm Capacitance: 10 nF to 100.0 µF Operating temperature: -10 to +50 °C Operating humidiy: 0 to 80 %RH Standards: EN 61326-1; EN 61010-2-032; EN 61140 Overvoltage Category: CAT IV 600V; CAT III 1000V Authorizations: CSA; CE Weight: 378 g Product colour: Black
