Multigas Setup
Sampling Lines
The sampling lines used with a 91518 Multigas Analyzer must be constructed of a material that will not absorb
anesthetic agents and cause erroneous readings. The correct sample lines are available from Spacelabs
Healthcare. Refer to
Parts on page 6-1.
Power Supply
The 91518 can be powered from the J3 SDLC connector from the patient monitor or module housing, or it can
be powered from an external power supply, P/N 119-0479-xx.
SDLC Bus Termination
The SDLC bus must be properly terminated for correct operation. Termination of the SDLC bus is
accomplished by means of terminator switches on the rear of the monitor and the multigas analyzer, or by a
terminator plug P/N 012-0507-02, when connected to a portable monitor.
