Note: When the iPad is connected through the App to the tester, the keypad on the Wired-Remote is
locked, as indicated by the message “Wireless Remote enabled. Keypad locked”, shown on the Wired-
Remote. The upper section of the display on the Wired-Remote will continue to be updated, even though
the keypad is locked. Once the App disconnects from the tester, or if the wireless connection is lost, the
keypad on the Wired-Remote becomes active again and the above message is cleared.
E.5
CLOSING THE APP
To disconnect the App from the tester, simply press and hold the Power key displayed on the iPad screen for
about 2 seconds. A tone will sound and the screen will appear as shown in Figure E.3 above. This indicates
that the App is disconnected from the tester. On the Wired-Remote, the message “Wireless Remote enabled.
Keypad locked” will be cleared, indicating that the Wired-Remote is fully functional.
Note: If the App is not closed as described above, the Wired-Remote will remain locked out. However, if the
iPad is turned off without closing the App, wireless communication will be lost and the Wired-Remote will
automatically revert to full functionality within about 20 seconds.
E.6
LOSS OF WIRELESS COMMUNICATION
Wireless communication between the tester and iPad may be lost due to several reasons include loss of Wifi
signal from the tester. If there is a loss of wireless communication between the iPad and the tester for more
than 20 seconds, the tester will automatically disconnect from the iPad App and the Wired-Remote will
become fully functional.
To reconnect the tester to the iPad App, in iPad Settings, check that the correct network is selected and restart
the App. The Power key in the App may then be used to establish communication between the App and the
tester.
Note: If the App is minimized during operation for more than 3 minutes, communication between the
App and the tester will be lost. Pressing the Power key in the App to first disconnect and then once more
to reconnect, will re-establish communication.
E.7
OPERATION WITH THE iPad
The tester can be operated with the iPad in almost exactly the same manner as from the Wired-Remote.
However, there are a few differences, as detailed below.
a.
Instead of having to make selections only with the keypad, selections can also be made by touching
the desired section on the screen. To change units, you can touch the area where the units are
displayed (yellow background), or the circled number shown on the display, or the relevant number
on the keypad. The same is true for target values (blue background) and modes (yellow ovals).
Other selections can also be done using the touch-screen on the iPad.
b.
Function 3 (Brightness) and Function 8 (Calibration) are not activated on the iPad.
E.8
HELPFUL NOTES
•
Ensure that you have selected the correct network corresponding with your tester’s serial number.
•
If the wireless connection is lost, or the iPad is not operational, you can continue to operate the tester
from the Wired-Remote.
