• Cleaning and sterilization of equipment should be performed in accordance with manufacturer’s instructions. The isolation barrier may be compromised if manufacturer’s cleaning instructions are not followed. PowerLab Teaching Series - Owner’s Guide... -
Page 8: Bio Amp Safety Instructions
• PowerLabs are compatible with electrical safety devices (sometimes known as Safety Switches, Ground fault circuit interruptor, Residual Current Devices or Earth-leakage Circuit Breaker). ADInstruments recommends the use of such devices supplied in fixed wiring installations. • Avoid using multiple portable socket-outlets (such as power boards) where possible as they provide an inherently less safe environment with respect to electrical hazards. -
Page 9: Isolated Stimulator Safety Instructions
• Always be alert for any adverse physiological eff ects in the subject. At the first sign of a problem, stimulation must be stopped, either from the soft ware or by flicking down the safety switch on the front panel of any built-in Isolated Stimulator. PowerLab Teaching Series - Owner’s Guide... -
Page 10: Cleaning And Sterilization
Cleaning and Sterilization ADInstruments products may be wiped down with a lint free cloth moistened with industrial methylated spirit. Refer to the manufacturer’s guidelines or the Data Card supplied with transducers and accessories for specific cleaning and sterilizing instructions. Inspection and Maintenance PowerLab systems and ADInstruments front-ends are all maintenance-free and do not require periodic calibration or adjustment to ensure safe operation. -
