Fuse is another crucial component of the Cen-Tech upgraded digital multimeter. Furthermore, measuring anything over 10 amps could blow a fuse or destroy the multimeter as well. When testing resistance in a circuit, the meter will transmit a small quantity of electricity from its own battery and then measure the amount that passes through the circuit or object. The fuses contain a thin strand of wire with a low melting point. Testing fuses with a multimeter is comparatively simple to do, and the equipment involved is cheap and easy to operate. The meter will certainly read among 3 points, 0.00, 1, or the actual resistor value. Approved. A digital multimeter (DMM) is one of the most useful test instruments in any automotive electrician’s tool kit. MANUAL Keep this instruction manual for future use.
