Fluke 107 ESP Digital Multimeter, CAT III, 600 V

The Fluke 107 ESP is a palm-sized digital multimeter engineered for field service technicians and electricians performing routine electrical troubleshooting and general maintenance. It delivers essential measurement capabilities in a compact form factor—142 mm × 69 mm × 28 mm, weighing just 200 g—without requiring True-RMS accuracy for everyday applications. The 6000-count LCD display refreshes three times per second, powered by two AAA batteries with a service life under 200 hours. Its IEC 61010-1 CAT III 600 V safety rating and Pollution Degree 2 classification ensure user protection in demanding field environments. The meter withstands 1-meter drops and operates reliably across 0 °C to 40 °C.

## Technical Specifications

The 107 ESP measures DC voltage to 600.0 V with 0.5% + 3 counts accuracy and AC voltage (40 Hz to 500 Hz) to 600.0 V at 1.0% + 3 counts. Current measurement extends to 10.00 A DC (1.5% + 3 counts) and 10.00 A AC (2.0% + 3 counts). Resistance testing covers 400 Ω to 40.00 MΩ in six ranges with 0.5% accuracy up to 400 kΩ and 1.5% accuracy at higher ranges. The instrument includes capacitance measurement to 5.000 mF, diode test to 2.000 V, and frequency measurement to 100 kHz. DC millivolt range spans 600 mV at 0.5% + 3 counts; AC millivolts to 600 mV at 3.0% + 3 counts with approximately 1 MΩ input impedance. Ohm test voltage is typically 2.0 V with short-circuit current below 0.6 mA.
