Based on the IEC test report description, and the appended table; does this mean that the "P Measured" is the average wattage during the typical use?
Or is the P Measured the maximum power draw measured during the course of the use of the product?
I have a blender which is rated to 300W; however I measured during certain stages of usage that the power draw jumped to around 600W.
How do appliance manufacturers calculate the type plate power rating that they put on the machine?
Is it average? Max possible peak (plus some buffer)?
Note...
Hello all,
I am working on a project where we need to perform EMC testing on our device to meet regulatory compliance. I was wondering if you could help me to interpret the meaning of the results; and what I'm exactly reading in the results.
The test results which I have are measuring the...
Thanks for the feedback so far! Aside from the electrical specifications, how about from the perspective of layout, pad-size, tracing, etc...
Could the adjustment of the pad size have any negative effects?
Does the smaller form factor impact how the designer does the PCB tracing, or schematic...
I am in a supporting role for a project to redesign some PCBs to use 0402 and 0201 package sizes, instead of the 0603.
What are some of the most important component specifications to take into consideration when making a design change like this?
EMC
Current carrying capacity
Self heating...
Hi,
I was wondering if it may be possible to use two piezoresistive pressure sensors to measure the surface tension of a solution?
In short, I am trying to figure out the feasibility of building out a low-cost surface tensiometer, so that I don't need something like the SensaDyne Surface...
Thanks for your response.
I also tested a parallel conductivity sensor from the same supplier and received similar results.
What is the difference, in this circuit, between having No Resistor and having a 10k resistor? How is the resistor or lack there-of, affecting the signal output?
I am testing a simple two-wire conductivity sensor from a Chinese supplier that didn't provide much information or data sheet.
I wired it up to an Arduino, and tested different resistor values with the sensor in some tap water.
I am trying to understand how the different resistor values are...
I have a machine that has a slide-in screen meant to collect dust, but I do not have visible access to that screen unless I pull it out.
I am looking to develop a small embedded system that can detect and notify the user when the screen is starting to be covered, or completely blocked with the...
I have a signal streaming in from an accelerometer (as shown in the photo below). As you can see, around the 80,000th sample, an event occurs.
I am trying to employ DSP techniques to be able to recognize when this event occurs. I am looking at rolling standard deviation, rolling mean, and...
Hi all,
I am analyzing a circuit, and I have noticed that the designer is using the ADS1232 TI Load Cell Chip (https://www.ti.com/lit/ds/symlink/ads1234.pdf), which accepts 2 differential inputs. TI has the ADS1234 model which accepts four differential inputs, but the circuit that I am...
