Product Description

Product Description

The Amprobe CR50A digital capacitance and resistance tester checks functionality and compatibility of electrical circuits and devices in home and industrial maintenance applications. When set to the low resistance or low capacitance ranges, the unit's zero-adjust pots help eliminate stray resistance and capacitance for more accurate readings. The included set of detachable test leads have test probe tips that are held against the conductor during use and shrouded banana plugs that help prevent shock if the plugs accidentally pull out of the meter while in use. The meter also comes with two alligator clips that fit on to the test probe tips to provide a more secure, hands-free connection than the probe tips. The meter's diode test checks for proper functioning of a circuit's diodes, and an audible continuity buzzer confirms that a circuit is capable of conducting current. The Amprobe CR50A is a manual-ranging meter and requires that the operator choose the appropriate operating range. The liquid crystal display (LCD) has a 2,000-count resolution, meaning it can display up to 1,999 units (3-1/2 digits) before the operating range needs to be changed. A low-battery indicator signals when the batteries need to be replaced. The meter comes with a carrying holster.

Multimeters are electrical test meters that measure multiple properties of an electrical circuit, such as current, voltage, resistance, capacitance, and continuity. Available in handheld or benchtop models, multimeters diagnose electrical problems in electrical equipment, wiring, and power supplies. A variety of probes, clamps, and leads can be used to connect the meter to a circuit or device. Multimeters display information either in analog or digital form. Factors that influence meter choice include the electrical properties to be measured, the anticipated range of results, and the desired level of protection against transient voltages. Safety ratings are based on the International Electrotechnical Commission's (IEC) standards for low-voltage test equipment. IEC 61010 delineates four overvoltage installation categories. In general, a meter with a category IV rating will provide more protection against transient voltages than a meter with a lower category rating.

Amprobe manufactures electrical testing equipment for commercial, industrial, and home use. The company was founded in 1948 and is headquartered in Everett, WA.

From the Manufacturer

Amprobe began life in Long Island, NY in the late 1940's under the name Pyramid Instrument Company. In 1960 the company name was formally changed to Amprobe Instrument Corporation. Amprobe continued to design, engineer, manufacture and distribute product from its Lynbrook, NY location until it was merged to form ATP and relocated to South Florida in late 1999. The Amprobe CR50A Red & Black Component Tester sorts, matches, inspects and verifys the components. You are able to check circuits with this full range capacitance and resistance meter and its oversized, read at-a-glance display. It has dual zero adjustment pots to null strays and test leads and a special “Low Ohms” range. Also the Amprobe CR50A Red & Black Component Tester comes with premium test leads with alligator clips and a low battery indication.

I can only comment of the capacitance portion of this meter's capabilities, as that is the portion I bought it for and use. The unit comes with the battery preinstalled, and initial setup is straightforward, I put it down into the nanofarad range to complete the zero adjust knob setting, to cancel out the capacitance of the leads. I would install a new 9V battery, a new battery always improves accuracy. And then I noticed it had those speed slits!

My favorite feature of this meter: you can remove the leads and it has those cool little slits in the front, enabling you to test a dozens of capacitors per minute! No fussing with leads to test capacitors, this makes this meter fantastic for checking a lot of new capacitors quickly!

Well I immediately started testing dozens of electrolytic capacitors from my inventory and I quickly could discern that the meter was extremely rock solid and repeatable in its measurements. I tested some known capacitors that I have used a $20,000 Agilent rig in our lab at work to measure before and the accuracy of this meter was very good.

This CR50A meter immediately identified which manufacturers of capacitors in my inventory are very accurate on the stated capacitance of their caps, it immediately singled out three brands of premium Japanese capacitors as standouts when it comes to getting the precise capacitance you ordered. (Rubycon, Chemi-con, and Nichicon) - I was disappointed with the tolerance for Panasonic capacitors although it was well within the +/- 20% spec, while their reliability remains first rate, they should really try and get their capacitors stated values to less than 1% like these other three aforementioned premium brands have managed to, rather than the 6% off or so I was measuring.

Great accuracy and repeat-ability of measurement. Awesome bang for your buck. I love Amprobe for my home tool kit. Yeah it doesn't have the crazy precision of an Agilent meter. But you also don't have to sell them your unborn child either to own one. Good tool and if you are in the market for a low priced capacitance/ resistance meter you can do a lot worse than this one.
