Slide3
Is the dial set to the correct setting?
3
DCV – Measures DC Volts
ACV – Measures AC Volts
Ω – Measures Resistance
ACmA – Measures AC Current in mA (0-200mA)
– Tests Diodes
– Tests Continuity Between Two PointsDC10A – Measures DC Current in MA (0-10A)
DCmA
– Measures DC Current in mA (0-200mA)
Battery Load Test – Tests small batteries
Slide4
Are the leads plugged in correctly?
4
Black lead should be plugged into the “COM” input jack. This is referring to ground.
Use this input jack when measuring or testing voltage (AC/DC), batteries, resistance, continuity, diodes, and small currents up to 200mA. This jack is more commonly used in our classes.
Use the “DC10A” input jack when measuring larger currents up to 10A. Dial should be turned to DC10A position.
Slide5
Did you blow a fuse?
5
Fuses get blown often when measuring current. It is okay if you blow a fuse; just replace it with a new one!
Fuses are blown most often when measuring current given these scenarios:
Current is greater than 200mA, but settings were used for less than 200mA.Current is measured improperly (e.g., if measured like voltage across components instead of through the circuit).
