a. Using an AC volt meter with at least
5Khz band width, measure the voltage
between J1-3 Exc and J1-4 Exc. The
meter should read 15Vrms ~ 5Khz ±
5%. If excitation voltage is low, turn off
power to the board and remove the J1
connector. Turn power back on and
recheck. If voltage is correct, check for a
short in Tensioncell cable assembly.
Repeat test for Cell #2 at J2.
b. With board power off, remove the J1
connector and measure the resistance
between the Yellow (J1-1 Sig) and Pink
(J1-2 Sig) wire terminals. The resistance
reading should be 335 ohms ± 5%. The
resistance between White (J1-3 Exc) and
Brown (J1-4 Exc) wire terminals should
be 100 ohms ± 5%. If readings are incor-
rect, disconnect cable at the Tensioncell
designated as Cell #1, and check resist-
ance between pins C and E, and A and
G. Repeat test for Cell #2 at J2.
13. Does the system zero? Press the SETUP
and EXIT keys simultaneously.
14. Does repeating Setup procedure help?
15. If problem(s) persists, contact your local
