• the tension frequency (Ft) and compression frequency (Fc)
(Each should be as stable as the other and within 10% of
each other. As weight increases the tension count should
increase and the compression count should decrease.)
• Cell size (30Kg for example)/Display resolution for maximum
efficiency (10000 is shown)
• Software version of the cell (vD.A in this example)
For analog bases you are shown:
• a raw count value and its equivalent mV/V value. (These
values should be positive and increase as weight is applied.
SERIAL Use this to test your ports. Select Port #1 or 2 then short the TX
and RX on the selected port. The display will change from NO
LOOP to LOOP indicating the port is good.
Port 1 is Comm1, a 9-pin connector. Short pins 2 and 3 for
Loop/No Loop test. Short pins 7 and 8 for Ready/Busy test.
Port 2 is Comm2, a 15 pin connector. Short pins 3 and 5 for
Loop/No Loop test on RS-232-A. Short pins 2 and 5 for Loop/No
Loop test on RS-232-B.
Port 3 is the local Quartzell. Use the local base test to verify
current cell communication.
