1) Place the 9750A in close proximity of the master CellScale unit. Make sure communications are good
(weight is on the display, all data types have been reported).
2) Press the function key programmed for “RF Site Testing”. The bottom right side of the display will read
“RF xx%”. The per cent reading indicates the ratio of successful transmissions. It will start low at fi rst,
then creep up. It should approach 100%, with an average reading of >96%.
If the reading does not achieve >96% within 1 minute try changing the CellScale Master device (MSI-9000, MSI-6260, MSI-9300, etc.) to a new network.
Usually the only thing that will interfere with a CellScale is another frequency hopping modem nearby. Also check your antenna connections on the
master.
3) Now start walking around the site with the 9750A. If the RF% reading starts down, stop and wait. Aim the
9750A towards the CellScale master and see if the RF% reading begins to rise again. If the display suddenly
reads “NETWORK”, you have lost communication. Return to the last place that communications were
working and wait for the 9750A to reconnect. In this way you can establish the range of adequate com-
munications, and note any areas with severe RF dropout. The location and height of the CellScale master
also plays a big part in range so be sure to run the site test with the CellScale in typical locations used in
your application.
4) Cancel the RF Site Test by pressing the function key again. If needed for some other function, reprogram
the function key.
RF SITE TESTING
The 9750A provides a means to check the effi ciency of RF transmissions using the RF Site Testing function.
Program a function key (use the procedure in Section 4) to “RF Site Testing” to run the test.
CELLSCALE NETWORK AUTO SCAN
For installations where multiple CellScale systems are present, the 9750A can scan every network and determine
if a CellScale master device is broadcasting. Found CellScales can be copied directly into the RF Scan List at the
end of the test. Turn on all CellScale masters (MSI-9000, 6260CS, 9300, etc.) that your 9750A will be used with.
Ensure that each CellScale master is on unique network addresses (see product User Guides).
1) Press POWER followed quickly by ESC .
It doesn’t matter if the 9750A is on or off.
2) Press NET/GROSS to start the scan. The 9750A will begin a progressive scan of all 64 (0-63) net-
works.
The scan can take as long as 15 minutes. If the backlight times out, press any number key to turn it back on.
3) Every CellScale master found will display along with its address. The end of the test will be indicated by
the display reading “ENTER Copy to Scan”.
4) If you want to store the found CellScale addresses, push ENTER . The display will read “COPYING RF
SCAN”.
5) Press DISPLAY to return to weight reading.
You can also press SETUP which will bring up the Setup Menu, or POWER which will turn the 9750A off.
