Acquisition Functions 147Setting up Gauge view for working with Blood Pressure Cuff Transducer SS19LA1. Connect the Blood Pressure Cuff Transducer to the MP acquisition unit.Connect the SS19LA to the desired MP input channel (CH1 – CH4); template is set to CH1.For MP3X units, it is recommended to plug in transducers prior to powering up the MP unit.2. Open the “SS19LA Gauge.gtl” template from the Sample Data\PRO folder.3. Calibrate the pressure cuff.a) Completely deflate cuff.b) Choose MP menu > Set Up Channels.c) Click View/Change Parameters (Wrench icon) for the channel the blood pressure cuff isconnected to—the Input Channel Parameters dialog will be generated.d) Click Scaling to generate the Change Scaling Parameters dialog.Default valuesCalibrated values (sample)e) Click "Cal1" to update the Input value. This value represents the baseline offset.f) Add the Cal1 Input value to the Cal2 Input value and manually enter the result as a new Cal2Input value.For example If the click on Cal1 produces an Input value of -0.1155 mV, and the existing Cal2Input value is 61.44, then the new Cal2 Input value is 61.44 mV - 0.1155 mV =61.32 mV (which should be entered as the new Cal2 Input value). So, aftercalibration, Cal1 Input value = -0.1155 mV and Cal2 Input value = 61.32 mVg) Do not change either Scale values orthe Units label—close out of the dialogs:i. Click OK to close out of the ChangeScaling Parameters dialog.ii. Click OK to close Input ChannelParameters dialog.iii. Click the close box in the upper rightcorner of Set up Channels dialog.4. Set Gauge Preferences (if not using template).a) Choose MP menu > Gauge to generatethe default blood pressure gauge in a“floating” window.b) Reposition the Gauge window such thatit is not overlapping the graph window.c) From the right mouse contextual menu,when cursor is over Gauge view,choose Preferences to bring up theGauge Preferences dialog.d) Change the lower Mapping Inputvalue to “319.11” mmHg.Calculated by the equation:359 degrees*(320 mmHg/360degrees) = 319.11 mmHgwhere 320 mmHg is a standard sphygmomanometer max value.e) Click OK to close the dialog.The Gauge is now set to display blood pressure cuff transducer values when data is recorded.
