Proster Clamp Meter - TRMS 6000 Counts Amp Clamp with AC/DC Current Voltage Capacitance Resistance Diode Temperature Continuity NCV/Live Clamp Multimeter with Storage Bag Test Leads

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.

muy buen amperimetro facil de operar y buena calidad

Keeping the electrical system in check is a constant task when living in an RV full time - and this clamp meter has become an essential part of my toolkit. It feels heavy duty in hand and the build quality is solid - which is exactly what I need when I am poking around in tight storage bays or checking campground power pedestals. The inrush current feature is perfect for monitoring the initial surge from my AC or water pump - and the LOZ mode helps clear out those ghost voltages that can be so confusing in a 12V system. It is packed with functionality - from NCV to frequency - and the backlit screen and flashlight are lifesavers when I am working in a dark corner of the underbelly. For the price - the value for the money is hard to beat - and the included storage bag keeps it protected.

Nice and accurate meter.
