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.
OVERVIEW OF UNIT
- 3.5mm (1/8 inch) Jack plug for connection to iOS device running App
- 3.5mm (1/8 inch) Headphone socket

For full instructions on using the meter and app, download the Loopworks
Measure User Manual from the R1 product page at www.ampetronic.comm
Method of use
- Download Loopworks Measure App to device
- Unpack Loopworks Measure R1
- Connect to the iOS device running the App
- 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.

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. Purchase an R1 Receiver from the Ampetronic website
(www.ampetronic.com) or through your local
distributor.
Sign up for Loopworks
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
Download the FREE App
If you haven’t done so already, you will need to downloa the FREE Loopworks
Measure App from the Apple App Store using your iOS device.
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.
Calibrate
Receiver
Follow the on-screen instructions to calibrate the receiver against your
iOS device’s settings. This is an important function to allow accurate meter
readings to be taken.
Sign in to Loopworks
After successful calibration you will be prompted to sign in when first
opening the app. If you have not already created an account you can register
within the app at this stage. If you choose not to sign in now, you can sign
in via the settings menu at any point. During sign in any existing data will
be synchronised to the app, you can check the synchronisation status and
manually synchronise at any point from the projects menu.
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.
