About this product


  • Ideal multimeter for general purpose use including household electrics
  • Measures AC/DC voltage, resistance and DC current so you can test common items
  • Low battery indication so you know when to change your batteries

Product overview

• Ideal multimeter for general purpose use including household electrics
• Measures AC/DC voltage, resistance and DC current so you can test common items
• Low battery indication so you know when to change your batteries
• Perfect for beginners and experts alike

What is this multimeter able to do?
This multimeter has a variety of functions. As a standard multimeter you are able to test for voltage in mains sockets by using the AC functions, and in power supplies by using the DC functions. You are able to test bulbs and fuses by using the continuity tester. For the more technical user, you are also able to test transistors and diodes.

How easy is this tester to use?
This tester is simple and easy to use. Once you have inserted the batteries, plug in the colour coded test leads and turn the dial to what you are wanting to test. The screen will then turn on and you are ready to test your items. The ease of use makes the multimeter usable for beginners and experts alike.

How safe is this multimeter to use with electrics?
The multimeter has fuse inputs to 200mA and to 10mA. It ensures that the fuse will blow before any damage is done. The supplied test leads are insulated to 1000V which means that even with using the multimeter with mains electric you will always be kept safe from electrocution.

Rated 4 out of 5 by from Great mutlimeter. Use mine in an industrial setting. (Factory maint) Small enough to fit in large pocket of trousers. First one lasted just short of 5 years. Got a more expensive type which lasted in the factory about 2 weeks. Now back with this. Robust with all the basic functions you'll need. Any negatives, well it's slow on reading, have to wait for about 1-2 secs for display to settle. Also the A-D conv reads slightly high, so 24Dc with read 25, 240ac will read 250. Unless you need high-speed reading with pin-point accuracy I can well recormend this item. Only quibble, no auto-shut off but power drain low seems but 9V batteries are easy to get. Rate 9/10.

Rated 2 out of 5 by from beware no replacement fuses if they blow Bought 3 days ago for my son. He blew the fuses in it within an hour ( his own fault) but you just canot get spare fuses anywhere for this meter. Maplin don't stock them and neither does any other UK company. They're very short 600V quickblow fuses. We now faced with having to buy a whole new meter instead of 2 cheap fuses. My advice, buy a different meter.

Rated 3 out of 5 by from Good value This meter has all the features needed for occasional domestic use and is good value at that level. The build quality is not up to professional meters, however these cost upwards of £100. So, fit for purpose at a very good price all round. Would be improved if a continuity buzzer was added.

Rated 5 out of 5 by from Excellent little metre Very good value for money, delivered on time, well packed and with strong sensible probes. Full marks.

Rated 4 out of 5 by from Good purchase? Arrived promptly and as described. I still have to work out how to get full use of it so cannot comment further.

Rated 2 out of 5 by from Misleading description This product doesn't allow you to test fuses using a 'continuity' test. The manual linked clearly shows that continuity is a feature of a different model to this product. Dispite Maplin's responses to reviews/questions. There is also no buzzer sound. Other than that, it seems to be a fairly accurate and easy to use. The cost is a little inflated.

Rated 4 out of 5 by from Good Value For The Money (At The Moment) Build quality feels good and covers functions I am likely to need (but as other reviewer points out no A?c current readings just volts). No doubt because I am a novice in this field I found the manual a little basic but a quick google search found very good tuitional videos and extended user guides

Rated 1 out of 5 by from not very acurate poor quality build does not read lower levels of resistance very well around 1-2 ohms and readings jump around even though connected to a constant resistance

how do I test continuity with this tester please?

Does this item have a continuity tester? It says it does in the description, but not in the product details?

Asked by: Simon
The linked manual clearly shows continuity is a feature of a different model than what is offered here. This product does not have a continuity tester.

The manual is the most useless I have seen.  Where does it tell you exactly how to test current - how to test fuses - how to test batteries?  Which leads go in which sockets?  Where do I turn the switch to in order to perform those tasks.  Not simple

Asked by: Paul
Normal continuity tests emit a beep when the fuse is good. This machine is impossible.

How do you set meter to test a fuse?

Asked by: John
Please tell me where to position the 'pointer' to test fuses!
Answered by: John
Date published: 2017-07-09

are both leads fuse protected? are the fuses in the probes?

Asked by: Steve B
The device is fuse protected, fuse is inside the multi meter.

OK, you say it can be used to check batteries. The manual supplied does not mention batteries - except the internal ones No mention of which of the 19 dial positions are to be used, or what range of display numbers indicate the charge state of the test

Asked by: JFM_IOM
This does have a Battery test function as stated in the user manual. Under section 9.
