Proster Clamp Meter TRMS 6000 Counts - Auto-Ranging Amp Clamp 1000A DC/AC Current 1000A DC/AC Voltage Inrush Current Test NCV Capacitance Frequency Diode VFC & LoZ, CAT IV 600V CAT III 1000V Safety

The meter works well in general 220ohm resistor(±5%) comes up as 218ohm. 5v dc power source (from ESP32) comes up as 4.98v. Frequency however is a completely different story maybe I'm doing it wrong but a 1kHz signal shows up with 200-900hz (consistently changing while reading) manual doesn't help under frequency it talks about measuring resistance rather than frequency. Temperature is right saying 19c in a room that's 19c. The clamp measurements vary wildly showing me current in unplugged un powered wires. I was hoping the clamp did ncv testing in the same way it doesn't and moving on to ncv feature, it's wildly inaccurate will beep like mad with red indication nowhere near a power source. However, value for money is there. The screen is very bright you won't have an issue seeing it in any lighting conditions. Its built solidly and mine included 600v 20a probes instead of the 10a mentioned in manual. All in all it's easy to use and has the correct protection features for the level of meter.

Very happy with this meter. I wasn't sure about the sensitivity, but it seems to be within 5 or 10mA with a 100mA current draw. Well made, compact, with a nice case. The thermo couple option is a very welcome bonus. Definitely would recommend it.

Have not used this in anger yet, have had a play around house with detection function, seems to work ok, so good for finding wiring behind walls if need be. The test probes look very flimsy, but sometimes you need very thin probes for testing in some places, would advise, when taking protective covers off probes, twist and pull holding below cap, as someone mentioned they pulled wire out, so just be gentle pulling them off, crock clips are a bit strange and awkward to use, they do not seem to fit correctly in the probes, hopefully I won’t be using them often, but you might be advised to buy separate cables with built on crock clips, the unit itself, seems to be very well made, everything is clear and easy to understand, cycling through the menus is a bit of a pain, but I can deal with that, the jaws are perfect for what I need it for, never going to test any wires over 28mm so they open wide enough for what I need, the clamp has a positive feel to it, like it’s not going to fall apart after a few uses, the torch seems good enough if you are in a dark place, I won’t know how accurate this will be yet until it is in line with another meter so we will see, it just feels like a great product all round, and I will be putting it through its paces soon, as allot of my job is testing. So we shall see how it goes, all in all, great price, well made, easy to use, instructions are well errrm you know, readable, so really no complaints here, would have given 5 stars but just because the crock clips are not any good, it’s 4, I would recommend this product easily.

All good so far useful light on amp clamp jaws makes easy to identify cables. Clamp feels solid and good quality

A lot of features in a small package at a cheap price. But there are some issues. First, the display is better viewed off-angle rather than head-on. When viewed head-on the brightness and contrast are diminished. The next issue is the one that worries me the most. When measuring voltage the display can take almost three seconds to display the voltage. Whilst this time delay is taking place the meter reads 0 (zero), not a great problem on low voltage circuits, but potentially not good on higher voltage i.e. when checking mains supplies, etc. The next issue is the mode selection is a faff as you have to increment through every mode until you reach the one you require.

I'm very impressed with this clamp meter and all it's functions. I've tested on AC volts to 425v, DC volts to 600v, DC amps to 560A and AC amps to 200A. All reading were close to a calibrated clamp meter I use at work. For the price you can't go wrong only being £44 when i got it. The build quality is very good and the materials used are OK. All in all a very good value for the monies clamp meter.

This is a great and very functional multimeter, with the added functionality of a current clamp meter, measuring AC and DC current. The user interface is fairly basic, with a single select button to cycle through the functions. Some function icons are dual purpose, with the AC and DC versions of that measurement selected separately as the SEL button cycles through. The probes (basic ones are supplied) connect to TWO sockets on the base of the device. Note that there is no probe input for current measurements - these are performed using the clamp only. The inclusion of a thermocouple probe was very welcome. The device also constantly displays the ambient temperature, presumably using an internal temperature sensor. I needed to use the current measurement function and I found it accurate enough for my purposes. One feature that I did notice that on the DC current range (I didn't try AC), it's rather sensitive to nearby electrical items, so the reading tends to vary somewhat if it is moved around while clamped round the wire being measured. Therefore I found it was best to clamp it round the wire (unpowered), then turn the meter on. The initial "CAL" process zeros the measured current. Then enable power in the wire being measured. Overall, recommended, and a useful addition to my measurement equipment collection.

Works great ✌️

Diciamo una classica cinesata fatta però con più criterio,molto preciso sulle misure,semplice da usare,ideale per chi si occupa di fotovoltaico,miglior prodotto per rapporto prezzo qualità,assolutamente consigliabile!!

Arrivato il giorno stabilito, la pinza funziona molto bene e i parametri anche se con piccole differenze uguali al mio tester digitale della Fluke.

Top Gerät in der Preisklasse selbst im Dauereinsatz.

I would give the build quality of the meter a 7/10. It feels solid and seems to be made from good tough plastic. There is a tiny amount of wiggle slop on the clamp mechanism, but I don't think this really affects the functionality as it sort of self-centers when the jaws close. The selector switch has firm detents and feels good when operating the meter. The rubber buttons don't feel great and remind me of a cheap membrane keypad. They sometimes require a firm press to get them to register, but generally work fine. The battery cover has a threaded metal insert instead of using a self-tapping screw into plastic, which I was happy to see. I tested the clamp meter on the 60A and 600A DC current ranges, as I believe that's what most people will be interested in. I use a 100-turn coil of wire to allow simulation of high currents with my bench power supply (that is to say, stimulating the coil with 1A of current will make the clamp meter read 1A x 100 = 100A). The clamp meter is zeroed out before the beginning of each range test. I have included photos of the results. 60ADC Range: Actual: 100mA Measured: 0.08A Actual: 1A Measured: 0.93A Actual: 10A Measured: 10.17A Actual: 60A Measured: 60.72A 600ADC Range: Actual: 10A Measured: 10.3A Actual: 50A Measured: 52.3A Actual: 100A Measured: 104.7A Actual: 300A Measured: 314.7A The results of the DC current testing are pretty good for a clamp meter in this price class. I've also tested the DC voltage range on some common DC voltage rail values to ensure they can also be measured accurately: DC Volts: Actual: 10mV Measured: 10.5mV Actual: 1V Measured: 1.005V Actual: 5V Measured: 5.007V Actual: 10V Measured: 10.01V Actual: 24V Measured: 24.02V Overall, after my testing, I think the meter is great. This would be a great meter for someones homeshop, for use in automotive testing/diagnostic, or even as a spare/backup for your yellow name-brand meter. The included case and accessories are all fairly good quality, and for the price, I think the whole kit here is a fantastic value.
