Maintenance SD32+ System
7. Maintenance
To ensure that the SD32+ amplifier operates properly and effectively, ensure that the signals are
calibrated, the cables and connectors are in good shape, and the equipment is cleaned on a
regular basis.
7.1. safety checks
Periodically check the SD32+ amplifier, and all devices connected to it, to ensure continued
efficiency and safety. Testing should include electrical leakage tests and should be performed at
least twice yearly by qualified biomedical personnel. Additionally, check the SD32+ system for
any dust deposits.
Perform a visual inspection of all connection cables and power cords for any signs of breakage or
improper connection. If such problems exist, contact a qualified representative at Embla Systems.
Note: Safety checks should be performed periodically and no less than twice a year.
7.2. operational environment electrical equipment
Inspection of the electrical wiring of the AC supply mains should be conducted periodically to
ensure proper grounding is available in the operating environment of the SD32+ system.
7.3. amplifier calibration
Semi-annually: Check the amplifier at various gain and filter settings. Verify the amplitude and
frequency characteristics of the resulting waveforms. It is recommended that each filter and gain
level be tested.
7.4. cables and connectors
Periodically check the integrity of all connection cables used with the SD32+ system, particularly
the fiber optic cable. Remove the cables from their sockets and ports carefully. Twisting or
pulling on the cables instead of their connectors may cause breaks or short circuits.
Monthly: Check cables monthly for abrasion and wear. Replace any cable with exposed wires or
shielding (wire mesh located just below the outer casing of a cable).
Check the connectors on the ends of the cables for bent or broken pins. Replace any cable that has
a damaged connector.
Check the connectors on the amplifier, headbox, and Sandman elink Adapter for broken or
damaged contacts. If any are found, return the unit to Embla Technical Support for servicing or
replacement.
