Hello,
I have a transformer PT01-3 and I want to use it to measure voltage.
The datasheet is attached.
There is a current ratio specified (1mA/1mA) but no voltage ratio.
Does it mean that when I connect 230V on the primary side, I will get the same voltage on the secondary side?
I measured...
I want to read the voltage and current at the output of the line with the PAC1934 IC. It is stated that the breakdown limit is 40V, but when I give a voltage over 32V on this line, I cannot view it and there is an underlined phrase in the datasheet Page 3. What does it mean? How can I read a...
I am trying to calculate the energy delivered by a short electrical pulse. I am using an oscilloscope to capture the waveform and then exporting it to a CSV file. My scope took measurements at a rate of once every 8 microseconds which means that each time time value could potentially vary by...
What are the ways to test a switching IC TOP266EG with a multimeter?
I want to check it if it is damaged or not.
Link to the datasheet: https://www.alldatasheet.com/datasheet-pdf/pdf/663154/POWERINT/TOP266EG.html
Here is the DATASHEET picture:
Here is the appearence of IC:
My digital multimeter starts fluctuating while I bring it near to my started bike even if the probes are not connected to any where .I can't read any value during that time.Therefore I cannot check my bike electrical circuit.My multimeter shows correct values when I connect to home ac supply...
Hello,
I'm currently working on a project, where I want to measure force using strain gauges. The strain gauges are configured in four point Wheatstone bridges. I'm using a four channel ADC. On each channel I feed in the amplified differential output voltage of a Wheatstone bridge. My question...
Hi All,
For my work it is becoming more common for me to measure lower, and lower resistances. Megger has a really good manual on how to measure down to micro-ohms (for example to determine the quality of bus bar joints etc). I have found the 4-wire measurement to be very repeatable, and useful...
Hello everyone, I'm a graduating Elektrical Engineering student, for my last year project I have to develop an prototype for an automated testsystem for electronic drive lines.
I started this thread to get help and tips about building this system.
First of all , I should make some dynamic...
I am tasked with confirming a report that said we had a large voltage spike (~400v I believe) when turning some equipment on.
I went and put the oscilloscope on our main that is in the same box for the switch for the equipment.
I throw the switch and see my measurements react a little but I...
Hi there,
Recently, I have designed a new charge amplifier than can be used to implement a precision and low-cost interface for piezoelectric sensors.
I have published an article about the novel proposed circuit in IEEE Sensors Journal. ( A brief information about the new proposed circuit has...
I am trying to get the value of the h field with a horn antenna as a reference antenna. I used a 90 degrees waveguide twist with the horn antenna in preset to measure le level of the received signal. But I am getting strange values.
Am I proceeding the right way to measure the h field? If yes...
