The UT136C just arrived!




First Impressions :

+ Nice sturdy construction, excellent LCD display.  Uni-T always uses very nice LCD displays!
+ I am using it with the Brymen leads from Franky.  Great combination.
   The leads that come with it are not of bad quality actually but they have a resistance of 0.15 ohms.
   Continuity testing with this combination is like a machine gun.  Instant.
+ Great frequency counter, fast and very sensitive.  That is actually the reason I've bought it.
+ Accurate and fast current measurements.
   Burden Resistance : 101 ohm @ uA, 1.84 ohm @ mA and 0.14 omhs @ A scales
+ Very positive feel on the dial, a bit stiff though.  No annoying beeping when changing modes.
+ Excellent tilt mount.  Stable.

- Probably the slowest resistance measurement I have seen in a multimeter.
  I thought I was measuring a large capacitor...  At least its accurate.
- 1.48V for diode measurement but fast.  Nothing great here.
  (Is it that difficult to make a proper diode tester?  !$@#$%)  21st century tech...
- Useless Hold button as usual.  Perfect for a backlight switch mod.
- Leads for temperature measurement complete junk!  Temperature sampling is fast
  but no decimal places.
- Placement of probe receptacles confusing.  A little red colour marking wouldn't hurt.
- (03 March 2014) Arrived 5mV out of calibration.  Fixed with adjustment of VR1 pot.


Overall a great little multimeter, especially for the price range. 
Perfect for my project because of its very fast sensitive and accurate frequency counter.
If you are measuring resistors frequently, look elsewhere.


The UT61E just gave birth to a cute little baby.   :)

Just blown the mA fuse of the UT136C while measuring current from a little motor.
Touched the spindle by accident while it was rotating...

I've replaced its fuse with a cheap one I had around, but now the mA burden resistance
went up from 1.84R to 3.84R.  While the A and uA are not really affected, the low voltage
mA measurements just became a lot worse now, just by using a crappy fuse with high
resistance.

Have you ever though about that?
Do you know the resistance of the fuses you are using?...

Ohhh, can't wait to get mine !
My old Mastech is already starting to go all over the place when taking voltage readings, although it did well for the past 2 years...

Hi, I just received a UT136C multimeter from gearbest but I have a problem with temperature reading. It always show OL. What does that mean? The probe is connected properly to the right slot. Maybe my multimeter is defective?

More likely is that the cheap probe is defective.

Where can I get a good probe?

There are probes available on ebay. The thing is you should get a replacement free from the seller of the UT136C. It is defective and they should replace it, not you.

I doubt gearbest will send me a probe for this.
I searched ebay but can't find the right probe for this. Will this one work? http://www.ebay.com/itm/DS18B20-Temperature-Temp-Sensor-Thermal-Probe-Thermometer-Waterproof-For-Arduino-/400805445386?hash=item5d51ddbf0a:g:40EAAOSweW5VG4tm

Is leads always problem with those cheap meters ? Seems like every sub $25 I've saw or owned developed a problem with them after some time. I've got pair of http://en.axiomet.eu/product/axiomet/test-lead/ax-tlp-001/106 and they are well worth it, better than ones most $100+ meters.

They basically have very sharp tip that pokes thru isolated cover (so it is hard to short anything by accident) and after taking it of it fits nicely into standard banana socket

I found out what the problem with my 136c temperature meter. It was the fuse. It was burn out. I removed the fuse and bypassed it by soldering a copper wire. Also the fuse for the 10A meter was burn out. I also bypassed it with copper wire.
What would be the effect if i don't use a fuse for the 10A meter? Will this make the ampere reading not accurate?

Fuses are there to prevent damage, so don't leave your probe plugged in the amp socket.
