    Loop Impedance Meaning Data Logger Troubles

    I am not understanding the difference between loop impedance and input impedance, nor do I even understand their meanings. I just copy and pasted from the site: Input impedance = 200k Ohm; Loop impedance = 50 Ohm So they should be what the specs are at the site's I provided. If not then...

    Loop Impedance Meaning Data Logger Troubles

    The input impedance is actually 200k ohm, and the load is 50. ( http://www.fouriersystems.com/products/8-channel/data_logger.php http://www.fouriersystems.com/products/8-channel/sensors.php ) The measurements usually aren't off by a standard ratio. Sometimes, the data logger reads a static...

    Loop Impedance Meaning Data Logger Troubles

    Hi! I am trying to measure the voltage through a "DaqPro", basically a data logger. I've used a voltmeter to get a reading, but then when I use the DaqPro it's totally off. So my question is--what does loop impedance mean, especially if it reads: (Input Channel Measure: 0 – 50.000 mV)...
