The Meter – 23

Electronic security technicians don’t normally have to measure the Amperage of a device. When voltage is present, it’s assumed the amps will be there.

“Amps” or “Current” is often measured when there’s a problem. Why is the device not operating properly when energized?

Amps are also measured when determining the current draw of a device or calculating the total current draw of a system. How many milliamps does each device use when energized? How long will my battery last?
