Klein Tools CL800 Electrical Tester is an automatically ranging true root mean squared (TRMS) digital clamp meter that measures AC/DC voltage, resistance, continuity, frequency, capacitance, and tests diodes via test-leads, and temperature via a thermocouple probe. It also features a Low Impedance (LoZ) mode for identifying and eliminating ghost or stray voltages. Klein Tools’ Test and Measurement product line was exclusively designed from the ground up by electricians for electricians. Years of field research, combined with extensive input from electricians across America, inspired the development of meters and electrical testers loaded with innovative, time-saving features.

what is the DC amp range this will read

Asked by happy November 13, 2019
2
Answers

The Klein CL-800 Clamp-Meter can read up to 600 Amps for both "AC and DC" Circuits, with the Clamp surrounding the "individual" Wire/Lead.. No need to insert the meter between the Line and the Load.. Typically a Line-Splitter is necessary for measuring AC-Current for 120V Circuits, as the White/Neutral-Return would Cancel the the "Hot/Back" Wire Reading of the AC Load.. Whereas, in the majority of DC Environments the Red and Black Wires are independent and separate, so a Line-Splitter is Not usually required for measuring DC-Amps..

do clamp meters clamp around th live wire?

Asked by rick July 30, 2019
4
Answers

I believe you should find a professional if you are asking this question. If you do not know the clamp is for live wires, what are you going to do with the information it gives you. Electricity has no smell and can not be seen but it will kill you.

Three words for the Klein Tools Receptacle tester with LCD, Quick, Easy and Accurate. Quickly checks your outlet for correct wiring. It's very Easy to use. The large LCD screen is very easy to read, and gives clear and concise information; even for those with less than perfect eyesight. The red and green indicator lights are bright and can easily be seen. It's a stand alone, (doesn't require power from the outlet like some other testers) operates on 2 AAA batteries and they are included. We tested it in different conditions and it gave us very accurate information. Another plus is the battery indicator; you will never have to worry about battery strength. It also holds your readings on the screen for 10 seconds even after you unplug it. We are very impressed with this tester. I only expect the best from Klein Tools and again they delivered.

Great product. I use this everyday as a home inspector. Besides the standard light indicator and GFCI tester, it also shows what the defect is (open ground/reversed wires), and the voltage. Very handy for report writing, as the client can see the read out on the screen. The voltage indicator shows voltage drop across the home. Fits in your palm. Highly recommended!

I replaced a standard breaker with a GFCI breaker and I needed to test the receptacles. It also showed that the wiring was correct. This worked perfectly and it was at a good price too.

Stick to hand tools Klein
This tester has a few nice features, but uses the same unintelligent style circuit as the old neon/resistor type testers. Just as in those, the tester displays HOT/GND REV when in reality it's an open, loaded neutral. Having a hot and ground reversed would be really rare in most instances, but an open neutral with something plugged in downstream is much more likely.

Great little tool. Fast go/no go and voltage readout performs two functions at once. GFCI tester allows safety check on kitchen/bath/garage/outdoor circuits. Pocket size makes a nice addition to my electrics kit.

I purchased this outlet tester because it is the first one I have seen that displays the actual voltage. I have not checked the GFCI test function as yet. Voltage readings are accurate and handy.
