Soren T. Lyngso query reg UMS 213 System
I have the Soren Lynso Universal Monitoring System fitted onboard. The vessel is built by Harland & Wolff in 1982. i have recently done lot of tuning up of the ship board computer system. System is built around and 8080 cpu and with 8k RAMs.
the tuning up procedure of A/D converter mentioned in the manual states to zeroise the analog display before adjusting the A/D converter but the procedure is not available with me. The system comprises of AC 1 analog cards with NO 2/ DBA cards for contact inputs.All the parameters read by the systme tend to read higher than actual values. Could it be possible to get the procedure for adjustin the A/D converter including the analog display. as it shows a value of + 565 with no input connected to it.
It would be very much appreciated if you can help me in this regard
