The Gunson 77038 is a fully featured but compact auto range digital multimeter for measuring DC and AC voltage, resistance, capacitance, frequency, duty cycle, diode and continuity. Measurements are displayed on the bright LCD screen and an LED spotlight is also included for working in dark areas. The multimeter is powered by two 1.5V AAA batteries (included).
The DC voltage range is 400mV to 600V and AC voltage range is 4V to 600V; resistance range is 400Ω to 40MΩ; capacitance range 4nF to 100μF and frequency can be measured in the range 9.999Hz to 10MHz. Over range protection is provided for all ranges and the device will power off after 15 minutes of inactivity.
