A. Transmitting Data Wirelessly following a Test Cycle Using the Test Options Menu
1. When newly generated test results appear on the handheld display, press (Test Options).
2. Press (Transmit Data). A
Waiting to Send
message will appear on the display screen.
Note 2.1:
If the user has not transmitted results within 120 seconds after the end of a test
cycle, the wireless module will power off to conserve battery power. Then, if a
user initiates a transmission when the radio is off, it will need to power on and
connect to the network prior to transmission.
The
State
line toward the middle of the screen may display a series of messages as shown
below or indicate that it is connected.
•

wireless module is off
•
Booting:

message will appear
at the top of the screen. When this message disappears and the display returns to the
Test Menu, the transmission is successful.
Note 3.1:
there are two additional parameters on this page which may aid the users in
troubleshooting and assessing the strength of the wireless transmission signal.
•
Signal:
indicates the strength of signal in one of three terms:
Weak
,
Medium
or
Strong
.
Additionally, an actual numeric measurement of the signal is displayed. If users are
obtaining failed transmissions when the signal strength is weak, they should re-attempt
the transmission in a location that provides a signal strength of
Medium
or
Strong
.
•
SNR:
(Signal to Noise Ratio): This is a measurement of a difference between the
strength of the wireless signal and the background noise level.
