UM25(C) Measure Type-C and Micro cable resistance same with UM24(C) and UM34(C))

Use our tester to measure the cable resistance to judge the cable resistance good or not , it is very useful
Measurement procedure:
First, connect the USB Tester directly to the power supply and adjust the appropriate load current (recommended value 1A). Press and hold the "Next" button to begin recording data. The indicator prompt will stop flashing.
Second, unplug the USB Tester and then reconnect it to the power supply via the data connection cable and adjust the load current to the same value as in the first step. Press and hold the "Next" button to begin recording data. The indicator prompt stops flashing and the Data Connection Cable resistance measurement test is completed and the value displayed.
Note: If during the second step the screen turns black, this indicates that the voltage difference is too high and the tester will enter the 4.5V power-down state. The load current needs to be reduced. Then re-start the measurement from the first step. After the Data Connection Cable resistance test is completed, the Tester needs to be powered off and then on again to resume measurement.

Finally i know how to use it :)

very god

Informative product use.

[@rdtech9153]

thank you , hope you like it

[@dantist06]

This may be an unusual request, but would it be possible to have the option of limiting the voltage- and ampere-numbers to three decimal places? I find it easier to read e.g. 0.375 as 375mAh than 0.3758.

[@rdtech9153]

thank you so much for your advice , I will consider this

[@dantist06]

That would be awesome. Is this something that could come via a firmware-update?

[@rdtech9153]

for now , there is not

[@EduardoSilva-os6ji]

So,low resistence is good or bad?

[@fritzmerkel3715]

For cables > good.

[@njfulwider5]

Love your Product and I have both testers. What would be cool!!!!! If you added the Apple Lightning Sync cable connector and Apple app.

[@rdtech9153]

thank you so much for your support . for app cable and app , I will consider
thank you again

Is it possible to chceck if USB-C cable has a 56K Ohm resistor with this tester?

[@rdtech9153]

you can use the type--c port to check

[@majeklol]

@@rdtech9153 how? :)

[@rdtech9153]

@@majeklol you want to measure cable resistance ?

[@majeklol]

@@rdtech9153 I want to check if CC pin of the USB type-C plug is connected to VBUS through a resistor Rp (56k Ohm) therefore confirm if USB type-C cable is safe to use at full power.
