Download the FREE App If you haven't done so already, you will need to download the FREE Loopworks Measure App from the Apple App Store, using your iOS device. 4. Connect the Receiver Start your new App and plug the Receiver into the headphone socket of your iOS device to activate it. You'll need an Apple Lightning adapter to use with the most modern iOS devices. For greater compatibility official Apple products are recommended. Follow the on-screen instructions to allow access to the microphone and enter the label number (digits only) printed on the side off the Receiver. Measure R1 www.ampetronic.com 1. Purchase Receiver You will need an R1 Receiver to perform any measurements in the app. The receiver contains a telecoil and enables your iOS device to accurately measure magnetic fields. www.ampetronMic.ceoamsure R1 Purchase an R1 Receiver from the Ampetronic website (www.ampetronic.com) or through your local distributor. 2. Sign up for LoopworksTM Create a free account to access the Loopworks online portal, and enable increased functionality on the App. This stage is optional, and you can use the App in simple meter mode; however, you will need an account to access the full range of functions and to be able to save data or record audio. Create an account from within the app or at loopworks.ampetronic.com INTRODUCTION The Loopworks Measure R1 has been designed in conjunction with the Loopworks Measure iOS App as a high quality piece of test equipment for detection and evaluation of the performance of Audio Frequency Induction Loop Systems (AFILS) to the international standard IEC 60118-4. It is simple to use with all types of installation, from simple service point applications through to low spill area coverage designs. Simply hold the Loopworks Measure R1 in the same position the hearing aid will be in once the system is operational: i.e. hold the unit at head height to take measurements: either seated, or standing depending on the venue. A headphone socket is provided to allow audible monitoring and subjective testing of the system. Details of use are given in the Hearing Loop test and commissioning procedure.

Download Loopworks Measure App to device 2. Unpack Loopworks Measure R1 3. Connect to the iOS device running the App 4. Insert the headphones into the socket on the top of the unit to monitor received signal. Adjust the volume using the controls on the device running the App. 5. Use as basic meter or sign in to Loopworks Measure to capture test results and generate reports 30 30 30 30 Page 2 N.B. For most applications it is the vertical component of the magnetic field that is received by the hearing aid, as a result the Loopworks Measure R1 is designed to be used while held vertically as shown: Ampetronic R1 Handbook Measure R1 www.ampetronic.com 30 30 -22 -12 -9 Home Advanced +8 +7 -2 -1 -3 -4 -5 0 +1 +2 +3 +4 +5 +6 1 kHz / 400 mA/m -5.2 db Unacceptable Frequency Response Field Strength Background Noise Test Perimeter Loop Instructions FSM 30 30 TROUBLESHOOTING No Headphone signal Check the headphones are plugged in, and the volume control is turned up. Low magnetic field strength Check the loop system is running current. If there is insufficient CURRENT, or excessive metal loss, the application may require a special loop design to achieve acceptable performance, contact Ampetronic for advice. Background noise Check all loop systems are switched off and not running any current. If the interference is still present with the loop system switched off, locate and eliminate the source of the interference before switching the loop system back on. Monitor with headphones whilst switching other electrical systems such as power, lighting etc ON and OFF See the full user manual, or the FAQs page within Loopworks for more troubleshooting advice.
