Measuring resistance
Hi everyone, I was seeing in software that already has a resistance test option how would the procedure be?

Re: Measuring resistance
Hello Marciooliveira,
Yes within the battery test we can see from the results we have calculated for resistance. This is simply done using Ohms law as we have measured the battery voltage and current draw using the x1 test lead and the 2000A current clamp.
If you need any further information regarding the battery test results please see this link the forum post - post77701.html#p77701.
Alternatively we can do the same thing within the PicoScope 6 Auto software using math channels. This can be useful if we can fix either voltage, current or resistance as a known value for example - using a 0.1Ohm resistor across the battery, then by recording the voltage across the resistor we can calculate the current as seen in this topic - post96371.html#p96541.
I hope this helps but if you need further assistance please get in touch.
Kind regards
Ben

Re: Measuring resistance
Good morning ben martins, I was referring to the oscilloscope probes settings, when the device blinded me I installed the software of the cd, then in this same option of the photo I selected resistance and it appeared on the screen in Mohms, now that I updated to the last one version appears in place of Mohms, appears Nm what would be problem in the software

Re: Measuring resistance
Hello Marciooliveira,
Please accept my apologies for not getting back to you sooner on this and thank you for clarifying your post.
From my understanding this probe was a creation for the Test and Measurement side of the business to work with the PT-104 logger. This does mean that the probe setting isn't compatible with our automotive scopes. Where the company is split between Test and Measurement and Automotive there is inevitable some cross over and this is what we are seeing here.
We have raised the issue with the software team and we will look to remove the Unknown probes from the list to prevent any future confusion.
If you wanted to calculate resistance the best way I can recommend is to use current and voltage. Applying a math channel we can create a formula based on Ohms Law - Voltage / Current = Resistance. This way we can keep the circuit intact and minimise intrusion.
If you need help creating or just math channels in general we have an ongoing topic here on the forum where we use math to reveal further information and detail. topic21311.html#p96371
Kind regards
