## Description

The CL900 Electrical Tester is an auto-ranging, true root mean square (TRMS) digital clamp meter. It measures AC/DC current via the clamp and measures AC/DC voltage, resistance, continuity, frequency, duty-cycle, capacitance, and tests diodes via test-leads. It features a Low Impedance (LoZ) mode for identifying and eliminating ghost or stray voltages, and has a dedicated mode for capturing Inrush Current. For more than 160 years, Klein Tools has manufactured premium-quality, professional-grade hand tools that deliver the performance, durability and precision needed to get the job done right. Our family of engineers, workers and craftsman continue to put six generations of expertise into every tool we create by using only the highest quality materials, superior workmanship, and keeping manufacturing as close to home as we can. Klein isn't just the name of our company, it's also our family name. And since we're an American company that's family-owned and family-run, you know you can count on us to be here tomorrow. Klein Tools doesn't just make great products, we make great products that stand up to the demands of the professionals who use them every day ... Since 1857.

Review: Great Tool - Excellent tool. Works as advertised. As always, klein tools deliver.
Review: Insanely good - This is one of those tools that you just find stuff to use and wonder how you went so long without one. Thing does so much. It does touch-less continuity and beeps if there is power. Has backlight and light if you want it. If you’re a newbie, you must educate yourself, but this thing covers everything for car to home. It has already helped me a lot. I keep finding more stuff to probe and test. Also very durable, well made. No regrets

## Questions & Answers

**Q: Does “voltage tester integrated into the clamp” mean that clamp close to a live AC voltage will signal a hot wire**
A: Just put the clamp to hot wire will show you a current not a voltage. For Voltage measurement you need a red and black prob to measure the voltage.

**Q: Does it come with a certificate of calibration or cane it be calibrated?**
A: No it does not come with a certificate of calibration. I do not think this can be calibrated

**Q: Can anyone who has any of the models that measure inrush current test to see if it can do so with dc or only ac like most ac/dc clamps inrush mode?**
A: Measuring charging amperage can be done in AC and DC- just press the set button to toggle between the two.

**Q: What's the difference between max/min button and the in-rush button?  won't max give you the max current during in-rush?**
A: It can detect in two ways. It will detect the in-rush if that is what you're looking w/ in-rush button selected BEFORE clamping. But if you are checking for any increase or spikes after the in-rush event, select the max/min button  option AFTER clamping. Work safe!

### ⭐⭐⭐⭐⭐ Best all around value out there
*by P***U on November 12, 2019*

I've had this meter for a while now and I have to say between features and accuracy this thing is worth every penny. If you need one meter that can damn near do anything this one is it. I own a fluke 28ii that is significantly more than this one. The klein is faster and very close in accuracy but carrys way more features. Great meter! 4-11-21 UPDATE I want to change my review from 5 to 5.5 stars. This thing has impressed me everytime I use it with my flukes. I'm reading low current draw 10X's magnified and getting the same exact readings as my $500 fluke with a $140 clamp and it in the mA setting. I'm still convinced this is the best all purpose meter you can buy.
