Electricians and Electrical Engineers employ the use of several tools and devices while executing their tasks. However, the multimeter for decades now has proven to be an invaluable device, especially in these fields. Multimeters are the ideal instruments for reading the values of voltage, resistance, and current. However, care must be taken when selecting a multimeter to purchase.

All of Harbor Freight’s multimeters have unique attributes that make them outstanding. These striking attributes that cut across all of them are their:   

  • High level of accuracy
  • High safety rating
  • Portability 
  • Very Affordable

Are Harbor Freight Multimeters Good?

Harbor Freight multimeters are not only portable but boast of a proven high level of accuracy in measuring voltage and electric power in residential settings. They are certified to have passed several safety tests they were subjected to. These multimeters have an easy to read LCD and are capable of measuring AC and DC and flow. And guess what? They are inexpensive too.

One of the most recognizable models of multimeters from the Harbor Freight brand is the 7 Function Multimeter. Also, we have got the Cen-Tech 11 Multimeter with an audible sequence. Another popular model from the Harbor Freight brand is the AMES Compact Multimeter. These multimeters are part of the Harbor Freight Tools.

How Do You Use A Harbor Freight 7 Function Multimeter For Beginners?

The Harbor Freight multimeter is one of the easiest multimeters to setup. The Harbor Freight multimeter usually comes with a battery that would be used to power the multimeter. So to begin:

  • First, have your probes plugged into their sockets
  • Then turn power it on by moving the power button located just below the knob to the on position.
  • Rotate your knob to the test you intend carrying out
  • Finally, using the tip of your probes, make contacts with test material to take measurements that’ll be displayed on the screen.

However, to use the equipment safely, the manufacturer gives some guidelines that must be strictly adhered to. These guidelines are outlined below:

  • Please note that the Harbor Freight multimeter should be powered by a 9V battery only.
  • When working near voltages which present the risk of electric shock, please exercise extra caution. Voltages with this potential are voltages above 30VAC true RMS, 42VAC peak or 60VDC
  • Please, do not use the Harbor Freight multimeter to test current on circuits that exceeds 20 mA.

The Harbor Freight multimeter should not be used to test voltage on circuits higher than 750 volts AC or 1000 volts DC. Voltages this high should not be tested by beginners. Please, the test must only be carried out by a qualified professional tester.
