• Generally – for all recordings it is best if subjects and other lab participants turn off their cell  phones and place them in their backpacks. This goes for FitBits, other “smart” watches and  Oura rings. 
• If using a laptop, make sure it is plugged in and not just using battery. This generally lowers  electrical interference. If the “noise” is too much, try unplugging it and see if it gets better. 
• Always connect the devices and turn on the software in proper order. This will ensure that the  hardware and software are communicating properly. 

◦ Plug the iWorx data acquisition box (like the IX-TA and IX-TA-ROAM) into the wall and  USB to the computer. 

◦ If you are using an iWire device (iWire-B3G for ECG/EMG/EOG etc… or any other iWire  sensor) attach it to the IX-TA. Plug it into the wall and power it on if it has an on/off switch. 

◦ Turn on the IX-TA 

◦ Open the LabScribe software 

• You have complete site license to download and install software on all computers on campus  and onto your own personal computer. IT may need to do this for you for the campus computers if you are not the system administrator. Software may also be given to students (Distributing  LabScribe Software to Students) 
• The first time using the software, Load the Lab Settings. 

◦ Click Settings → Load Group → CompleteSettings 

◦ Choose IPLMv7Complete.iwxgrp and click OK 

◦ Click Settings again and choose the Lab you would like to do 

▪ The Setup PDF for that lab will open automatically 

◦ After choosing the Lab – click the “Experiment” tab for the rest of the lab documentation. 

• Many of the sensors are sensitive to movement. It is important for the subject to stay as still as  possible during recordings of things like ECG, pulse, GSR, and others. 
• Using the Wireless ROAM unit with the IX-TA-ROAM system: 

◦ The IX-TA-ROAM needs to be plugged in and turned on for the ROAM to charge. ▪ Leave enough time for the ROAM to charge before you are going to use it in lab. ◦ Each ROAM has a dedication TA box – do not mix them up. The serial numbers will match. 

◦ The LCD screen shows the Bluetooth connectivity “staircase” which shows that the ROAM  is communicating with the TA box.

▪ If you do not see the staircase, reconnect the ROAM to the TA box. 

◦ The LCD screen also shows the charge on the ROAM battery. Generally 15% charge is  enough to get through a whole lab. 

▪ Like a cell phone battery, the ROAM will lose charge even if not in use. 

• The AutoScale All button on the toolbar will automatically scale your recording to the screen so it looks good. This icon can be clicked throughout the recording to keep the data maximized in  the graph. 
• The “mountain peak” icons adjust the amount of data seen on the screen. Two mountains zoom  in and increase the amount of data; the single mountain zooms out, so you see less data on  screen. This can also be changed in the Display Time window. 
• If the pulse (PT-104 or PPG-320) sensor is not picking up a pulse – trying loosening or  tightening the Velcro strap. 

◦ The subject should just be able to feel the pulse in their finger tip. Too tight and it cuts off  circulation, too loose and it won’t pick up the slight changes in pressure. It also works better if the subject’s hands are warm. 

• For blood pressure labs, it is important to practice letting the air out of the cuff before putting  the cuff on the arm. The air should be let out at a rate on 10mmHg/sec. Too fast and the BP will  not be calculated correctly. Don’t forget that the pulse sensor goes on the finger of the same arm with the BP cuff. 

◦ There is an automated BP system you can purchase if you do not want to use a manual one. 

• For spirometry labs, the subject should practice breathing through the flow head before the start  of the experiment. They need to inhale AND exhale through their mouths only. If they use their  nose, the recording will drift in an upwards or downwards direction. 

• It is also extremely important that no air move through the flow head during the first 10 seconds of recording so that the software can calculate baseline.  If the subject starts breathing through the flow head during that 10 second period, the recording will drift.

• Cleaning – Cleaning the iWorx FH-300 Spirometer Flow head ; or you can use the Student Respiratory Kits which include a bacterial/viral filter, mouthpiece and nose clip (A-SRK-100)
  

• When using the ROAM in Scope Mode, a communication delay can occasionally cause a flat  line to appear during a recording sweep. If this occurs, simply run another sweep; there is no  need to return the ROAM to the dock to reset it.
