34/83
Version 1.0
Sensitivity Setup
This is a functionality that can modify sensitivity of the output signal, when the outputting signal’s amplitude is too large to cause overlap with neighboring signals, or too small so that signal diagnosis is difficult.
Users can set all 12 channels to 2.5mm/mV, 5mm/mV, 10mm/mV or 20mm/mV. Users can also set it to Auto which will automatically set the sensitivity level for each channel; for example I, II, III, aVR, aVL, aVF to 10 mm/mV and V1, V2, V3, V4, V5, V6 to 5mm/mV.
Note that 10mm/mV means printing 1mV signal as 10mm in amplitude on the printing paper
.
To change the sensitivity of the signal, select and enter the wave amplitude menu on the main display ( ) using the rotary key or touch screen, and open the setting menu display shown above. After that, use the rotary key to select the desired sensitivity level and press down to enter or select it using the touch screen to set the size of waveform displayed on screen.
Selected values are shown on the bottom of EKG printouts in the following way: when 2.5, 5, 10 and 20 are selected, they will be displayed as “all channels:
2.5mm/mV,” “all channels: 5mm/mV,” “all channels: 10mm/mV” and “all channels:
20mm/mV” When Auto is selected, sensitivity level will be printed as “I-aVF: 10mm/mV,
V1-V6: 5mm/mV.”
The left side of the graph display will show the channel name and a bar graph, so users can notice recently changed values easily. (For 20mm/mV, only one bar graph will appear so that overlapping of indicators does not occur.)
Printing Speed Setup
This is the function used to adjust the width of the signal displayed. Three values, 12.5 mm/s, 25 mm/s, and 50 mm/s are available for adjustment. 25 mm/s means to record the signal of the electrocardiogram for a second on 25 mm. Therefore, the width of 12.5 mm/s is a half of the width of 25 mm/s, and the width of 50 mm/s becomes two times the width of 25 mm/s. If you want to record the broad width of the signal, set up the higher value.
35/83
Version 1.0

The signal output generated by the device may contain extra unwanted signals in addition to the EKG wave such as AC noise, base line drift caused by respiration, noise generated by an electrical field nearby, etc. Applying filters could help to reduce or remove those unwanted signals from the output of the device.
To change filter information, enter the Filter Setup Menu either by moving the selection block over and select it using the rotary key or by touching the menu on the touch screen.
Upon selection, the Filter Setup menu, shown below, will appear. Use either the rotary key or touch screen to navigate and select menu items to edit. After editing,
OK must be selected in order to apply the changed value.
If the recorded EKG signal contains a lot of noise, Low Pass Filter (LPF) may help to clear it. For Low Pass Filter, 40Hz, 100Hz, 150Hz and OFF option is offered. Here, 40Hz option means the filter will remove any unwanted signal with frequencies above
40Hz. Low Pass Filter values will appear on the bottom of the printout form; if LPF setting is OFF then as ~250Hz; if the LPF setting is 40Hz then as ~40Hz; if LPF setting is
100Hz then as ~100Hz; if LPF setting is 150Hz, then as ~150Hz.
62/83
Version 1.0
There are three types of an AC power noise filter; 60Hz, 50Hz and OFF. When set to
OFF, the filter will not be applied. If the filter is set to 50Hz or 60Hz, then the AC filter will remove 50Hz or 60Hz power noise correspondingly. In the U.S., the AC filter should be set to 60Hz. Check the properties of your power source before setting AC filter properties.
Under battery power, there would be no AC noise being generated. In this case, please set the AC filter setting to OFF so that output signal would not be distorted.
The status of the AC filter can be checked on the bottom part of the printout - indicating AC 60Hz, AC 50Hz or AC OFF.
Base line drift is caused by the patient’s breathing. It can be seen as ECG signals being overlapped on a large parabola. To remove Base line drift from EKG printouts, select ON. Otherwise, select OFF. The set value will appear on the bottom part of the printed form indicating 0.1HZ- when set to ON, and 0Hz- when set to OFF.
Electromyogram is caused by the patient’s organs or muscle parts. When the ECG is recorded on patients with strong electromyogram responses, the ECG output
63/83
Version 1.0
may not be clear. In Cardio M Plus, electromyogram can be eliminated by using the Muscle Filter. Select ON to apply the filter to the output and OFF to get the unfiltered output. When you switch on the filter, EMG is indicated on the bottom of the printed form.
The use of filters can distort the original output. Therefore, you may reduce the possibility of signal distortion, if you set the filters OFF when the signals are clear. For your reference, we recommend that Baseline and AC filters be set to ON most of the time. Use of the electromyogram filter should depend on signal conditions.
When there is a lot of noise in the output, it is recommended that the LPF filter be set to 40Hz.
In this menu, users can set the device to ring an alarm sound when a QRS beat has generated while it is in waiting mode. Users can either set the alarm ON or OFF by selecting the menu with ON turning on and OFF turning off the alarm sound.
