Combination with other devices
Connecting additional USB devices and high processor load
can reduce the sample rate and therefore cause an error. We
strongly recommend not connecting additional USB devices
except mouse, keyboard and printer and not installing
additional software. Please contact your local dealer for
further information.
Always ensure all connections and cables are connected
properly when using the Spirostik complete together with
other devices. All connected devices must comply with legal
regulations and the total leakage current must not exceed
the maximum allowed valued specified in the Norm DIN EN
60601-1.
For some non-medical devices a higher case leakage current
is allowed. Those higher limits can only be accepted outside
patient area. It is essential to reduce the case leakage
current, if such devices are used within patient area.
The Following table (source: DIN EN 60601-1-1, table BBB.201)
explains the combination of medical electrical devices with non-
medical electrical devices:
