As you will notice, the selector knobs gives me many options. Here are some of the features of the multimeter:<\/p>\n<ul>\n<li>AC\/DC Voltage Measurement<\/li>\n<li>AC\/DC Current Measurement (up to 20A!!!)<\/li>\n<li>Continuity\/diode tester (with buzzer, thank god&#8230;)<\/li>\n<li>Ohmmeter<\/li>\n<li>Capacitance-meter (okay, not the right name&#8230;)<\/li>\n<li>NPN\/PNP Transistor tester<\/li>\n<\/ul>\n<p>Tons of features. The great thing about this multimeter is its performance is dependent to a certain degree on your soldering and assembly abilities. The assembly guide had tests at the end of the most sections, which I completed and passed each one (I lied, I didn&#8217;t complete the transistor testing and the capacitance measurement, as none of my other multimeters could measure these, and I didn&#8217;t have a transistor or capacitor lying around (within close proximity)). There is virtually no variance between this meter and my Mastercraft &#8220;control&#8221; meter.<\/p>\n<p>Wall voltage measured:<\/p>\n<ul>\n<li>Mastercraft: 120.4VAC<\/li>\n<li>Dan Joannis \u00a9: 120.1VAC<\/li>\n<\/ul>\n<p>Win.<\/p>\n<p>I know I throw safety to the wind, as my first AC voltage test was with wall voltage, as I don&#8217;t have a variable AC PSU.<\/p>\n<p><a href=\"https:\/\/blog.danjoannis.com\/wp-content\/uploads\/2010\/01\/HPIM1783.JPG\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-170\" title=\"DMM: It works!\" src=\"https:\/\/blog.danjoannis.com\/wp-content\/uploads\/2010\/01\/HPIM1783-300x223.jpg\" alt=\"DMM: It works!\" width=\"300\" height=\"223\" srcset=\"https:\/\/blog.danjoannis.com\/wp-content\/uploads\/2010\/01\/HPIM1783-300x223.jpg 300w, https:\/\/blog.danjoannis.com\/wp-content\/uploads\/2010\/01\/HPIM1783-1024x763.jpg 1024w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<p>Here is proof that it turns on!<\/p>\n<p><a href=\"https:\/\/blog.danjoannis.com\/wp-content\/uploads\/2010\/01\/HPIM1784.JPG\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-171\" title=\"DMM: Rear, holster\" src=\"https:\/\/blog.danjoannis.com\/wp-content\/uploads\/2010\/01\/HPIM1784-223x300.jpg\" alt=\"DMM: Rear, holster\" width=\"223\" height=\"300\" srcset=\"https:\/\/blog.danjoannis.com\/wp-content\/uploads\/2010\/01\/HPIM1784-223x300.jpg 223w, https:\/\/blog.danjoannis.com\/wp-content\/uploads\/2010\/01\/HPIM1784-763x1024.jpg 763w, https:\/\/blog.danjoannis.com\/wp-content\/uploads\/2010\/01\/HPIM1784.jpg 1920w\" sizes=\"auto, (max-width: 223px) 100vw, 223px\" \/><\/a><\/p>\n<p>And here is the rear, with the lead-clips, allowing me to conveniently store them on the sides.<\/p>\n<p>Pretty sweet kit, and I&#8217;m glad I didn&#8217;t mess it up.
