    First of all, the probes aren't quality. The item is running two AAA pen batteries. The live end feature is nice. Don't expect good performance from the NCV feature. He ca n't find the sub-plaster cable. I didn't expect it anyway, the screen is big enough and legible. It has a flashlight feature. AC and DC are good with current measurement. I gave the photos an AC current measurement photo, but it's not normally measured like that, I know I just had to do it through phase or neutral. The warning sound and the warning light are pretty strong. Good product for the price. The temperature reading is working well too.

    It took a long time to wait because it was pre-order, and then they changed the expected delivery time twice. It's a nice little instrument, surprisingly small for the usual size of the lock trappers. Surprisingly accurate, I expected worse for that kind of money. The logic of the buttons is a little unusual at first - there are usually several buttons on the instrument, three buttons have done everything - but it is quickly used.

    Маленький, удобный прибор. В автоматическом режиме измеряет ток переменки. Постоянку замерял, оказывается, что надо соблюдать полярность( на губке обозначено и + и -).

    C21 Digital Clamp meter with a lot of good functions. Included in the box were the Clamp Meter itself, a pair of Positive and Negative probes, a temperature-sensing probe, and an instruction manual in the English language - no other languages are included. It takes 2 AAA batteries (not supplied) with the battery door cover held in place with a single screw. The device itself seems to be well made and is a little heavier than I was expecting. It includes a large, crisp, and clear LCD display that can be easily read during the day, or when in low-light conditions. Included is a small white LED that sits between the two clamps that can be switched on to provide enough light to be able to see what you are doing during low-light conditions. The C21 Clamp meter measures AC Current 400A max (+ or - 2.5%), DC current 400A max (+ or - 2.5%), DC Voltage up to 600V (+ or - 0.5%), AC Voltage up to 600V (+ or - 0.8%), Line on-off test (buzzer sounds when less than 50 ohms), Resistance 600 ohms - 60M ohms (+ or - 0.8%), Diode (resolution 1 V, with accuracy 0.001V, Capacitance 60nF - mF (+ or - 2.5%), Temperature -40 to 1000 degrees C, or -40 to 1832 degrees F (+ or - 1%), Frequency 60Hz - 1000Hz (+ or - 1%). My own testing seems to be within those ranges but can differ depending on where the cable is positioned within the Clamp. For the price, this is a reasonable device and will get you the information you need. Overall, its build quality is excellent and small enough to be transportable. A great addition to a tool bag.

    The perfect thing, all in one. It's just the temperature doesn't show very accurately. Auto-recognition, it takes a bit to record. Battery how to replace is not in the manual, but I finally found the bolt from the cover under the round sticker. When no value is measured, the values fluctuate on the scale, that confused me. Otherwise, I'm happy, there's no competition at the price.

    Hi, great product. Other measurements standard. But, DC Current measurement with clamp true. My review video there

    The package contains instructions for use, a probe for measuring temperature, two positive and negative probes and a multimeter. The probes are of good quality, one meter long each, and have a thin tip for better measurement. It is powered by two AAAs (not included with the product). The screen does not have strong backlighting, so it will be a bit problematic to see the result in the sun. All in all a good product.

    This is a good product, with good quality for this price. The display is visible and of excellent quality, we find classic features of many products, namely: ohmmeter, ammeter, frequency meter, continuity, measures AC / DC current, AC / DC voltage, low impedance mode, rated automatic scale, less impressive frequency, resistance, capacitance, diode, continuity test and temperature. In automatic mode, the reading time is slow, but the readings are quite accurate. This is a mandatory device when performing electrical activities. Thanks. Best regards, Dimitar Dimitrov.

    Arrived in less than 3wks. Works properly: measures 226.3V AC at 50.00 Hz. NVC is detected. Haven't tried measuring current with the clamp yet. Works on NiMH batteries too, but the display is a bit dim then, so better use alkaline batteries.
