Fluke 120 serial number DMxxxxxxx

[yaromka]

Hello! help to identify the serial number Fluke125, tell me please is it possible to read using the opto cable or display on the device. A sticker with the number on the back was lost...maybe someone knows about additional ones inside the instrument? Thanks.

I tried using the terminal program to transmit the request "*IDN" the answer is "1" and the request
 "ID" answer "FLUKE 125;V03.04;2008-06-10;English, French,German,Dutch,Spanish, Portugese,Italian, Japanese,Korean,Chinese". But the serial number was not displayed...

I believe fluke meters that have been repaired (replacement pcb) always show as s/n = 1

Stupid, but true.

This happened to user tony3d as well for his Fluke 287:
