MULTIMETER

2 types of Test Probes

-Negative Probes (Black) -Positive Probes (Red)

MULTIMETER USES

-Voltmeter -Ammeter -Ohmmeter

Digital

-measures with great accuracy -reading in numeric form appeared on an LCD -calibrated automatically -accept multiple input -has adjustable displays

Analog

-prone to error -calibration is done manually -display one input signal value -provide reading on a scale against pointer
