Can this measure miliamps. Im troubleshooting car electrical issue and need to measure mAmps

Asked by IamQ May 2, 2020

Answers

For this particular multi meter, you can measure between 200mA and 10A. Seems like this range should cover your application but, I am not sure of your specific range for your car that you need to be reading.

Does this unit come with a calibration certificate?

Asked by MolecularExpress March 4, 2020

Answers

I went thru the paperwork I rec'd and did not see a specific separate calibration certificate. I am 99.999 % certain each meter is calibrated at quality control check and recorded in conjunction with the specific serial # as part of ISO 9002 compliance.

Seeds Program Review
(What's this)
The Klein Tools MM300 is a great compact multimeter for use around the house or on a job site. The meter measures AC/DC voltage, DC current, continuity, and resistance. There also is a setting to test batteries, diodes, for continuity. The meter also has a built-in stand, and test lead holders integrated right into the meter housing. Requires 2 AA batteries which are included.

Seeds Program Review
(What's this)
As the pictures will indicate, the LCD screen never lit up and there were no other signs of life from this device when turned on in spite of replacing the included batteries with new AAAs and following the instruction manual to the letter. It is a nice, durable looking instrument which just doesn't work. The instruction manual included directions to remove the back in order to replace the fuses. I did this and checked the fuses which were OK. Still - no joy! Serious disappointment.

Seeds Program Review
(What's this)
This Klein MM300 Multimeter can measure AC/DC Voltage, DC Current, and Resistance. Can also test Batteries, Diodes and Continuity. Has a Hold Button and a large bright digital readout. Just make sure that you insert the test leads (Black & Red) fully into the meter. They have to click/lock into place without any gaps. This is outlined in the directions. I compared this unit with my neighbors $600 Multimeter and I found it to be 100% accurate. This meter is made out of high impact shock absorbent plastic with a built in stand and 2 clips on the back to hold your test leads in place. Each lead is about 39in. long and the tips can be removed to expose a longer test lead if needed. Uses 2 AAA batteries included and instruction manual included. Also a low battery indicator.

Great tool. I'm an industrial electrician and mechanic with 15+ years experience working on everything from motor controls to circuit board level components. Love the manual selection knob on this. This one is a tool that you can use exactly how you want it. (It'll measure ohms when you want to measure resistance, and volts when you want to measure volts). Not expensive, or complicated but gets the job done and works well.
