Upgrade |
| Notes: |
Upgraded to 7500A with the 7500-600 LI-7500 Head Upgrade kit from Licor. I put in new bottom assembly and greased o-ring, screws and greased o-rings, and two chemical bottles. I also adjusted the potentiometer until the waveform displayed about 15,000 counts for the minimum and 55,000 counts for the maximum(Diagnostics icon > Waveform tab). I confirmed the Signal Strength coefficients (B = 1.6, C = 3.2) and reset the signal strength to 100% after cleaning the windows (Calibration icon > Signal Strength tab > Reset Signal Strength). |
