The FNIRSI-1014D is a very cheap instrument and at this price it gives us much more. An update of firmware required, you have to be in contact with the whatsup FNIRSI Technical support (some delay will be occured because is time of the comapany vacation). There is a difference at voltage measurements (Vpp and Vrms) channel 2 has an error of about 4% at 19 volts AC input voltage, channel 1 of my instrument is ok. The frquency measurement is very accurate. I received it without the EU plug adapter and i asked from Banggood to send me it. Also the photos of the FNIRSI-1014D are streched the real width is more than the heigth, see the attached photos. In any case for that price I recomend it, especially for a begginer.The people of the FNIRSI Technical support and of banggood are the best for the customer service.

  • atlanko It does not display a signal smaller than 30mV (on a range of 100mV), the smallest sensitivity is 100mV, so it is insufficient. Errors in the firmware.
