View history entry 3780 for Licor LI-7700 sn: TG1-0423

Date: 2018-10-29
From: Lab - none
To: Lab - none
Title: Upgrade
Notes: I swapped out power board pn 9677-073G per Licor's instructions. The new power board is pn 9977-079. According to Licor the original boards Rev 0, could be damaged by exposure to voltage above 24VDC. The new board Rev 0A (V3) should not have that problem. Note: This instrument was replaced with 2 original screws and 2 long screws. The long screws were used to help re-assemble the instrument, and I forgot to swap them for the original, shorter, screws.
