Two of the most valuable test instruments that any electrician can have in his tool kit are a digital multimeter and a digital clamp ammeter, or a digital meter that combines the two in one. One can spend several hundred dollars on such a meter. These expensive professional meters have many bells and whistles that the professional electrician need, but the average DIY electrician can easily live without. Easy to set up and easy to use The rotary function switch allows you to select between 3 AC Ampere ranges, 2 AC Volt ranges, 4 DC Volt ranges, 5 Resistance ranges, a Diode Test and a Continuity test. These ranges cover all the measurements encountered by the DIY electrician when working around the home. If one is taking a reading in an area where it is difficult to see the display, one can lock in the reading by simply pressing the hold button.
