View history entry 3792 for Licor LI-7700 sn: TG1-0421

Title: Upgrade
Notes: I swapped out power board pn 9677-079G per Licor's instructions. The new power board is pn 9977-079. According to Licor, "the original board needs a new resistor for the "under-voltage" problem (potential to drop out when heater and washers run simultaneously while incoming power is lower than usual, say 11-10 VDC)". The new board Rev 0A (V3) should not have that problem.
