SigQa2
Characteristic for the robustness of echo pulse detection in relation to interference
pulses.
Not active in foam mode. The displayed value is only valid if the sensor displays the
correct level value.
• Value range: 0% ... 100%
• Good signal: > 50%
b Measures: Run AutCal; check installation conditions; remove deposits from probe
and process connection.
SigQa3
Characteristic for signal noise and electromagnetic interference.
• Value range: 0% ... 100%
• Good signal: > 75%
• Poor signal: < 50%
Not active in foam mode. The displayed value is only valid if the sensor displays the
correct level value.
• Value range: 0% ... 100%
b Measures:
• Increase EXPRT-Cong-TrsHld
• EXPRT-Cong-MeasMd = HiAcc
• Improve ltering
• Switch on lter
• Reduce EXPRT-Cong-MaxCol
8.4.10 Changing the coaxial cable length
• Valid for versions with remote amplier.
• This setting makes it possible to congure the coaxial cable length between the
sensor head and process connection.
Conguration
Predened coaxial cable length (1,000 mm, 2,000 mm, or 3,300 mm)
1. Log in to expert mode; see “8.4.1 Expert mode”.
2. Congure the coaxial cable length in the EXPRT-Cong-CblLen menu
(1,000 mm ... 3,300 mm).
