today i got an interesting package from
the company
which also produces these small
oscilloscopes so let's open it
and look what's inside and interesting
device great youtubers here is
the guy with the swiss accent with a new
episode and fresh ideas around sensors
and microcontrollers remember if you
subscribe
you will always see in the first row
tweezers and
a display the display is detachable
and it changes direction according
how you have it in your hands and this
is important for me as a left-hander
i can read it it should be able to
measure everything which can be
measured by this lcr meter
and of course i will compare it with
this one
for that i have prepared a few
smts which are not easy to measure
with a bench multimeter
also one diode a larger one to show you
that it's also
possible to measure normal through-hole
components
so let's start i put it on
automatic now the software is
not completely stable sometimes it does
not
what i think it should do so i'm in
calibration
i close and i open
and now i can save the data
it has an automatic mode
let's try the automatic mode now let's
take the first one
it says 9.11
nanofarads
9.8 nanofarads so it's quite close
next one
this one seems to be an inductor
i do not know if you see it 11.5
micro henry let's check
12.7 micro henry so it's also
quite close next one
should be a resistor 62.1
ohms
61.78 so very close
now the last one is this one here
and you see what happens it is a
diode an led and
it has a forward voltage of 2.52 volts
now i cannot measure this with
this device i have to measure it with my
multimeter
the multimeter does not show anything
it cannot measure high voltages of leds
it only can measure lower voltages
the led we have to measure with an
other tester it's not easy
2.87 volts
so here they disagree 2.2 volts
and 2.87 volts 2.9 volts
but at least you can check if it works
or not
so let's look at the data sheet it can
measure from
0.1 ohm to 2 mega ohm that's okay
from one pico ferrato that is very small
to 400 micro farad so this is also
a reasonable range maybe here it's a
little bit low
sometimes i have one thousand or two
thousand microfarads
and i cannot measure this with these
tweezers
also inductance one micro henry to 50
millihenry
okay the voltage is from one
millivolt to 40 volt but there is one
thing
maximum input voltage minus 5 to
plus 50 volt and i'm not sure
what happens because here is plus and
here is minus now i assume
if you mix it up with
plus 30 volts or so and if you touch it
the wrong way around
then it might be destroyed i do not want
to
check it but i'm not sure if it is
protected
it has also a built-in frequency
generator
which can generate sine waves and square
waves
it's not easy to handle for me at least
the device only has one
button here where you can switch modes
or automatic and calibration and stuff
like that
but i can imagine that if you want to
change the frequency for example that's
not easy i did not find out how
uh how to do that but this is not a huge
problem for me
because um this is more a specialty
i like the idea that i can go
and check my smds without any problems
it's much easier than with these if you
put it on automatic
then it's quite comfortable now this is
a inductor
this is a capacitor and this is a
resistor
i did also some other checks and
these two agree quite a lot there are
some differences but for sure not much
more than the
accuracy stated here on the data sheet
and
i think also this is i would not
use this as a precision meter it is more
a comfortable thing
you can identify quickly
your parts and even
leds nice
now this is a pre-production device
i even do not know the pricing for the
moment but i'm sure
you will get this information later on i
leave you a link
in the description now you can assume
that it has a battery built
in and the battery is somewhere here
so to charge it you get
this wire with a usb
c and if you are in a hurry you still
can continue to measure during charging
it automatically switches on and off you
just
touch the tweezers and then it starts
and after a while it switches off so
these tweezers
will not replace this device
plus the multi the bench multimeter but
it for sure will make it much easier i
assume that i will not use
this much more just for transistors and
stuff like that
but for sure not for other components
this one will stay
in the shelf much more because it's
very comfortable and this will have a
place on the bench very close to my
working
area because i will use it all the time
i assume
this was just a short update about a
cool gadget during my holidays
but i had to do it bye
