If a certain lead record appears as a baseline on your Fukuda Denshi Medical Equipment, check the patient cable for any breaks and verify its connection status. Also, inspect the operation of the OP Amp, IC23 to IC27, and A/D converter IC37 (related to the baseline lead) and the transistors Q13 to Q21 for protection against excess input to ensure they are not shorted.
What to do if all 12-lead patient records appear as baselines on Fukuda Denshi FCP-7101?
If all 12-lead patient records appear as baselines on the Fukuda Denshi Medical Equipment, check that 125kHz rectangular waves are input to IC20 pin 13 and that reversed rectangular waves are input to IC20 pin 15. Also, ensure power is supplied. Check that 8MHz rectangular waves are output from X2 pin 3; if not, X2 may be faulty. Verify that IC38 pins 5 and 7, [RXD] and [TXD], are not set to “H” or fixed to “L.”
What causes detection of electrode misposition cannot be led on Fukuda Denshi FCP-7101 Medical Equipment?
Check the signal line (around IC23 and IC24) where electrode misposition occurred.
