The Klein Tools ET250 is a top - notch solid - state digital tester for voltage and continuity. It can accurately measure AC/DC voltages up to 600V and quickly test for continuity. Besides, it's great for checking GFCI protected circuits to make sure the GFCI device works well. This tester comes with a backlight and an integrated flashlight, making it easy to use in low - light areas. What's included in the package? You'll get (1) set of test leads and (3) AAA batteries. The ET250 has many useful features. It automatically selects voltage or continuity and powers on when you start measuring. The backlit LCD display is clear and easy to read. With its CAT IV 600V modern solid - state design, it ensures safety. It uses standard replaceable multimeter test leads and has built - in test lead holders on the back. The integrated flashlight adds to its convenience. It can withstand a 9.8 ft. (3 m) drop and is IP53 dust and water resistant. In terms of specifications, it's a digital voltage and continuity tester. Its application includes measuring voltage, testing continuity, and ensuring GFCI devices function properly. It has a built - in test lead holder and an integrated flashlight as special features. Made of thermoplastic and electronics, it runs on 3 x AAA batteries. It offers 9 - 27/32 ft (3m) drop protection, has a digital LCD display, and digital control. It can handle 2 to 600V AC/DC and a frequency of 45 to 400 Hz. Its ingress protection is IP53 (except test lead jacks), with a pollution degree of 2. It can test continuity, has integral lead storage, and meets the CAT IV 600V and CE standards. The package includes test leads and batteries. It measures 6.06' (154.0 mm) in length, 1.64' (41.7 mm) in height, 2.31' (58.8 mm) in width, and weighs 6.00 oz (170.0 g).
Using the Klein ET250 is easy. First, make sure the 3 AAA batteries are properly installed. Then, connect the test leads to the tester. When you want to measure voltage or test continuity, just bring the test leads to the appropriate points. The tester will automatically select the right mode and power on. To check GFCI protected circuits, follow the normal testing procedure and see if the device responds as it should. In low - light conditions, use the backlight or the integrated flashlight. Keep in mind that this tester is designed to handle up to 600V AC/DC, so don't use it for higher voltages. Also, avoid using it in extremely dusty or wet environments, though it is IP53 dust and water resistant. When it comes to maintenance, replace the test leads if they get damaged. Check the batteries regularly and replace them when they're low. Store the tester in a dry and cool place, and use the built - in test lead holders to keep the leads organized.
