UNI-T UT210D/UT201E Digital Clamp Meter True RMS Voltage Resistance Capacitance Multimeter Temperature Measure Auto Range Electrical (ABS)

For the price, this handy little Meter/Tester is well worth buying! The fact that it measures not only AC but DC Current too, is worth the price in itself. To date, I am very impressed. Granted it isn't perfect but it's pretty damned close. Acceptably accurate, even if you have to keep 'zero-ing' to obtain an accurate reading. The probes that are included are a tad slow when testing for Continuity, but this is down to the probes rather than the Tester. As such, if you're fussy, you may want to use some better-quality ones. Also, the included storage bag is a little soft and flimsy. It's better than nothing but a harder case would provide better protection..... Again, for the price, one can't really complain. I'm left-handed, so the trigger being situated on the left, works Very Well for me, whereas if I hold it in my right hand, I find it awkward to use the trigger but maybe you Right Handers, don't have that issue! All in all, a Very Nice bit of kit that is very handy...... Literally, as it sits very comfortably in one hand, is simple to use and view the readings which are very/acceptably accurate. Basically, Highly Recommended!!!

A very good clamp meter. Tested thoroughly on DC low currents and seems quite accurate. Easy to use. Good display.

Nice solid feel, but I wouldn't think it would last too long being bumped off the bench onto a hard floor. This is the best amp clamp I could find for under £50, which was my budget, considering I already have a couple of traditional multimeters. I needed an amp clamp to measure current without breaking a circuit and voltage in cables where accessing terminals is difficult to reach and manage current spikes on load. You can read the spec for this and compare with other models in the UNI-T range, so won’t list spec here. It is easy to use and performs well, the clamp opens to about the width of your finger which is enough for small applications. Voltmeter is accurate down to 0.01V in the voltage range and 10mV in the millivolt range. Current is not as accurate. If you are measuring large current, the Amp range is acceptable but in the mA range, it could make difference depending on the component requirements, TV, computer, PSUs, other sensitive electronic circuits, but for general indicator for diagnostics this is good enough for the price. I do find the auto ranging function sometimes not performing at all, and sometimes taking a long time, sometimes having to constantly select the AC/DC switch or the rotary dial. I would like to see auto ranging for current without the need to select 2A and 20A, sometimes the meter struggles to display reading appropriately. I needed to see mA but the meter decided to display A range, removing my need to see current value to the accuracy I needed to measure, 0.01A could be anything from 100mA to 199mA and needing to determine 150mA made using this a bit difficult. I have not checked but other amp clamps in the range might perform better but I did not check and suspect the price would easily go over £50 I would also prefer the meter to either have a mechanical AC/DC switch or an AC/DC setting with memory, so not having to constantly switch to DC every time I switch the meter off or change the dial, because it always defaults back to AC.

Good bit of kit, pocket size and accurate

This is a brilliant meter, well made, compact and versatile. Like most people reading this review I thought that clamp-on meters could only measure a.c. current. But this meter genuinely measures d.c. current. The meter can indicate currents as low as 1mA but as may be expected the effect of the earth’s magnetic field can cause errors and care must be taken to zero the meter in the orientation in which it is to be used before making a measurement, otherwise errors as high as 50mA be result. I’ve not done a detailed estimate of accuracy but when measuring d.c. current I would expect an error of +/- (5 + 10%) mA. So, it is best used for fault finding rather than precise measurement. N.B. This meter can be used for a wide range of tasks but you cannot use the test probes to measure in-circuit current.

I am a former Electronic engineer at Daresbury Laboratory a UK government research laboratory near warrington.I like making things and I admire real craftsmanship not just in electronics.I bought this from Truustdeal circa £31 and it arrived within 5 days just in time to sort out an electrical problem on my car. Buying clamp meters can be a bit of a minefield in that many imply they can measure DC current with the clamp and they cant they can only measure AC current .This one can do it all and lots more besides and it fits easily into the hand. The problem with the car was that something was discharging my new car battery overnight ( the car had done 123,000 miles).I put the clamp meter over the battery earth lead and something was taking 3 amps.I put the mini clamp meter on the alternator lead and it was that what was taking the 3 amps.Obviously one of the alternato diodes had failed.I picked up an alternator from a vehicle scrap yard for £20 fitted it - problem solved The other thing I used it for was to check standby loads of electronic equipment on our house electricity supply. on the 2A DC range you can see 1mA 20 A 10 mA and if the direction of the DC current changes a minus sign comes up. I think the mini clamp meter is a credit to the design team and it is so easy to use well done guys Colin Horrabin B Sc ( Hon ) Eng

I bought this clamp meter primarily because , as an amateur interested in electronics, I was fed up with having to rejig breadboard circuits to put a multimeter in series whenever I wanted to make a quick current measurement. With this device, and a bit of forethought when laying out the circuit (e.g. judicious use of flexible jumper wires which leave enough spaces to insert the clamp) I can get a pretty accurate measurement down into the tens of milliamps ranges. It is in the nature of a clamp-meter's (induction) measurement mechanism that the readings won't be as accurate as a proper in-line meter; but I did a couple of tests comparing with an in-series multimeter and the results were within 5% one another - good enough for what I want. There were several reasons for choosing this particular model : (a) most important, it can measure DC current, as well as AC (many only do AC); (b) it is fairly compact, with a smallish clamp - good for getting into small spaces on a breadboard ; (c) this specific UNI-T model (UT210E) has a selectable range down to 2amps (which, with its 1999 count, makes it good for milliamp measurements). As a bonus, using the supplied probes it will do many of the things an ordinary multimeter will do (voltage measurment, DC & AC, continuity testing etc) , so I got an extra multimeter into the bargain. All-in-all, I am very happy with this purchase.

Before use, I verified the DC current and voltage accuracy of this instrument using recently calibrated equipment (typical accuracy 0.05%) and was very impressed with its performance. For low currents (0-100mA) the meter was measuring within 3mA of the actual current at higher currents (0.1 to 50A) all readings were well within the specified 2% (Did not test between 50A- 100A). The voltages were within specification. The only thing to be aware of is the meter does take some time to settle to the correct reading so if the current under test is varying reasonably quickly (within say a period of 10 seconds) then you may have difficulty with the accuracy, so for this case would recommend a current shunt. For the price this is an excellent instrument for current measurement where you do not want to or its not practical to break the circuit under test.
