Service Manual

CombiScan 100

1. General information This service manual describes the control and repair of the Combi Scan 100. It is written for use by a well trained service engineer, who is experienced in repairing and maintaining instruments for diagnostic investigations. The operations, which are described in this manual, should never be carried out by the enduser of the instrument. The Combi Scan 100 is a precise and costly calibrated optical measurement system. The listed operations below must be accomplished with special attention and precision. Please take special care to disconnect the device from the power supply if this is required by the instruction. If spare parts or accessories are needed, it is absolutely necessary to use only original spare parts for this instrument. Nevertheless, even a well trained service engineer will not be able to do all operations to get a defective Combi Scan 100 working again, because for several operations special equipment is needed. Depending on the problem, it might be necessary to send the instrument back to Analyticon for repair. More detailed information can be found in this manual. If a return of the instrument to Analyticon is recommended by the manual, please contact Analyticon first to agree on the further steps. Never send the meter back to Analyticon without any written confirmation of Analyticon to do so. If repair operations are carried out, they are done in the responsibility of the company who does the repair. If the meter is opened for repair, Analyticon will not take any further warranty for this instrument.
