in this video we're going to be reviewing the met1000 electrical tester from Megger
now the key thing that we want to emphasize first of all is that this met1000 is not a multimeter
it will measure voltage resistance and current and even carry out phase rotation tests but
it is absolutely not a multimeter it is an electrical tester it even says it on there you see
electrical tester not a multimeter why am i laboring this point
because of this direction in gs38 which is a guidance note on electrical test equipment for use
on low voltage electrical systems published by the hse it states where a test is being made simply
to establish the presence or absence of voltage a proprietary test lamp or two pole voltage detector
suitable for the working voltage of the system should be used rather than a multimeter the use of
incorrectly set multimeters or makeshift devices for voltage detection has often caused accidents
so this is not a multimeter it is primarily a voltage indicator and complies with all the
relevant requirements for a voltage indicator that is used to prove safe isolation from the
things you may not normally think about like the fact that it not only complies with bsen61243-3
but also has that information as well as all the voltage categories it can be used on
permanently embossed into its surface you may have already noticed that this tester requires two
aaa batteries to operate correctly however even if we remove the batteries as you can see here it
will still operate as a voltage indicator and can still be used to prove safe isolation more on just
how it complies with gs38 in a moment first let's discuss the additional functions it can carry out
now most voltage indicators will give you an idea of the band of voltage that the tested electricity
falls within but won't give you an accurate reading to the volt however we're already starting
to see this is not your typical voltage indicator and it can be used to measure voltage right down
to 0.1 volts perfect for checking the voltage and say an ev charger that seems to be tripping off
for no good reason it will also measure resistance from one ohm up to 50 kilo ohms this is achieved
simply by pressing the button here until you get an amiga symbol down here in the bottom corner
and then you can use it to measure the resistance of components as well as specific measurements of
resistance it can also be used as a continuity tester if the meter hasn't been triggered simply
connecting the probes together will place it in this mode and it can then be used for the
usual purposes such as tracing conductors when your colleague has forgotten to mark the ends of
the cables up and if you've pressed this button and set the mode it's in then you can return to
continuity mode by a long press on this button and just to complete the triumvirate of avo testing
it can also be used for measuring current by using this fork section at the front here for this test
you must remove the leads from the sockets on the base of the tester and then it's simply a matter
again of pressing this button until you've got an a down in this bottom corner of the screen and
then position it so the conductor to be measured sits in the base of here so you can see here this
conductor has between 29 and 30 amps running through it and it will measure up to 200 amps
notice though that as with all cramped type meters it's important not to put the line and neutral in
there as they'll cancel each other out and you'll read zero current the exception of course being if
you're testing for earth leakage current check out the video we made on how to do that by clicking
the link above my head the met-1000 however has some features that makes it stand out in the crowd
such as a single pole phase check where you remove one probe for safety and then use the remaining
probe on a terminal and if the circuit is live it will sound and flash when connected to the
line terminal and remain silent when connected to the neutral and you can even use it to carry out
a phase rotation test on a three-phase circuit speaking of the probes if we look at the tips
on here for a moment you can see there's a couple of different options that we can connect to them
there's these ones that have a lot of metal exposed and these are perfectly acceptable for
use when you're using the meter to test resistance and bell out circuits and also for connecting to
four mil test sockets but if we unscrew them then we get these pointed probes left behind
and unscrewing the other accessories provided onto the ends of these we get a tip where only
two millimeters is exposed and that then complies with gs38 for making connections and testing to
live terminals the tester also has these moulded holders that the probes sit in and can either be
used to test in this position or one held in place and you're free to move around or of course both
can be detached and used freely for contacting awkward to reach terminals and i don't know
about you but i'm a nightmare for losing essential little bits and bobs like this unfortunately the
met1000 comes with a little holder that sits on the test lead here and there's a port to contain
each of the lead accessories so the blanks sit in here the four mil tips go in here and the gs38
tips live in this section here another couple of features that we absolutely love about this tester
include the fact that the leads are replaceable which means that should these ever become damaged
in any way you can replace just the leads not the entire unit another feature is that it comes with
a belt carrier as standard so you don't have to pay any extra for that which is fantastic
and of course earlier in the video we saw this tester being used outside in the rain and it's
perfectly suitable for that because it's rated at ip65 meaning that it can be used both inside
and outside in slightly wet conditions and finally if you hold this button here down for two seconds
there's a torch in the end here that illuminates for the less than perfect testing situations that
we find ourselves in from time to time so there we go this is a great electrical tester that can be
used for measuring various electrical values and also be used as part of a safe isolation procedure
to prove dead but as always we want to hear from you what do you make of this electrical tester
will it be on your wish list when it comes to your next voltage indicator are you carrying out
rigorous safe isolation as part of your day-to-day work whatever your thoughts and questions please
leave them in the comments section below and as always thank you very much for watching
