as shown in a picture here, you will see the meter being tested to a car battery. If you DC test it above 9 volts , you will fry it !
For a battery tester, it is great for the price. The battery companies don't want you to know about this product....HeHe
I looked for this meter at my local Walmart. After much searching I located model # 10729W, made by E-Tek, but it was black-faced only without the yellow accents, only took 1-AA battery instead of 2-AAA, and did not have the pouch (located in Automotive section). Otherwise it appears to be an identical meter. The website indicates this meter could be found in the Household / Electrical/Dimmers section, but it was not there. Perhaps E-Tek updated the product design a bit. What I needed the meter for was to measure .5 ohms resistance across the 3 terminals of a motorcycle stator to ensure the stator was working properly. Even after "zero'ing out" the meter in the lowest resistance setting (10 ohms), the meter was reading ~0 ohms resistance across the terminals, likely because the reading was taken at the extreme bottom end of the 10 ohm scale. You see, this meter's resistance accuracy is rated +/- 4% of the selected range's *full scale*, so on the 10 ohm scale it could read off as much as a .4 ohms. (The meter's manual is careful to point out that readings should be in the 4th quadrant of the scale being used for best accuracy.) However, the meter's redeeming grace is the calibration dial on the side. After adjusting the meter to an exact known-good .5ohm load (two 1ohm resistors wired in parallel) and measuring again, it turns out the stator's terminals were right at the .5ohm specification. For DC similar inaccuracies can be expected. For instance, when working on automotive circuits (12-14VDC) the closest range the meter has is 50V and DC accuracy is rated at 3% of full scale, meaning you can expect readings to be off +/- 1.5VDC, which is quite substantial if accuracy is desired. Overall, this is an okay meter to throw in the glove box or "spare" toolbox, but certainly should not be considered a lab-grade piece of test equipment, nor should one have that expectation with a meter in this price range. For knowing if voltage is present or not and if the voltage is in the ballpark area it needs to be, this meter will do just fine. Knowing how to calibrate the meter against a known-good load for resistance checks can yield accurate results despite the unit's poor range of scales (2.5V, 10V, 50V, 250V, and 500V DC.... 10V, 50V, 250V, and 500V AC... 1 ohm and 1000 ohms DC).
cheap but useful for simple around the house stuff that's all I brought it for
