How to test the meter:
Insert the two probes. Insert the Black probe in the “COM” jack. This is the COMmon, or ground, connection. The Red probe should be in the “V” jack. This connection is for measuring voltage. It can also be used to measure resistance in Ohms, or frequency in megaHertz, on the meter shown here.
Through a few steps, I basically learned how to test the meter to be functional.
After that, the Lab introduced what are the controls in the meter. Voltage, amperage, resistance, continuity, diode check.
Learning how to measure each of the following,
Volts: V
Ohms (resistance): Ω
Amps (current): A
AC: ~, ⏦ (tilde, sine wave)
DC: ⎓
Continuity: diode, speaker
Diode Check:diode
Non-Contact Voltage: NCV
Ground: ⏚ (vertical line with three horizontal lines below it)
There are auto-ranging meter and non auto-ranging meter. Many meters are designed to measure many different things.
Questions after the Lab: How do we user meter to correct our mistakes when designing a circuit?
Lab Process:
Two LEDs were burned.
When I was trying out connecting two LEDs with a switch, one of the LEDs does not light out.
