■ Changing the Time Constant
The default setting of the time constant is “0.4 seconds”.
If a stable monitoring is difficult with excessive change in the baseline due to
excessive body motion of the patient or an interference noise, such as AC
frequency, by changing the time constant to “0.1 second” the monitoring may
become relatively stable.
For details of the setting change, contact your local Fukuda Denshi service
representative.

CAUTION
When changing the time constant to “0.1 seconds”, the lower frequency
characteristic becomes 1.6Hz ±25%. This setup does not meet IEC
60601-2-27 standard. It may lead to a change in the ECG waveform and
ST measurement value may be especially affected. Fukuda Denshi
recommends “0.4 seconds” setting in normal use.

The LCD screen in normal use does not indicate the selection of time
constant. Make sure to take measures, such as marking on the LX-
7230, to distinguish whether the selection of time constant is changed.
