Overview The Fluke 9040 is effective for measuring phase rotation in all areas where three phase supplies are used to feed motors, drives and electrical systems. The Fluke 9040 is a rotary field indicator and can provide clear indication of the 3 phase via an LCD display and the phase rotation direction to determine correct connections. It allows rapid determination of phase sequence and has a voltage (up to 700 V) and frequency range suitable for commercial and industrial applications. The included test probes have a variable clamping range for safe contact, also in industrial sockets. Includes 3 self-retaining test probes (black) alligator clip user manual Features 3 phase indication Indication of phase rotation Clear LCD display No battery required Specifications Technical Specifications Voltage Range 40-700 V Frequency Range 15-400 Hz Operating Timer Continuous Environmental Specifications Operating Temperature 0°C to 40°C Dust/Water Resistance IP 40 Safety Specifications Electrical Safety EN 61010, EN 61557-7 Overvoltage category CAT III, 600 V CAT IV, 300V Mechanical and General Specifications Size 124 x 61 x 27 mm Weight 200 g Power supply From unit under test Warranty 2 years
