The three instruments in the testo 770 clamp meter family are ideally suited for current measurement in switching cabinets. One of the two pincer arms can be fully retracted into the instrument. This unique grab mechanism means that cables in tight switching cabinets can be easily grabbed. The automatic measurement parameter detection also ensures reliable work: in the current and voltage area, all three instruments detect direct and alternating current and select other parameters such as resistance, continuity, diode and capacitance automatically. The testo 770-1 model is the standard version for daily measuring tasks, including starting current measurement. The testo 770-2 also has a µA range as well as an integrated temperature adapter for all type K thermocouples. In addition to this, the testo 770-3 offers a performance measurement function and can be connected with the testo Smart Probes App by Bluetooth. In the App, you can display the measurement progression as a graph and document it directly in the report.
