"Y2:"
parameter variation allows changing the angle position of
threshold level in Y2-direction. Y2 parameter variation is carried out in the
range from 32768 to
- 32768 with a step of 1, 10, 100, 1000, 10000 (see Figure 17).
Select the frame polarity "Pol:" which makes the alarm trigger:
– the signal gets beyond the limits of the threshold level;
– the signal is within the limits of the threshold level.

GUIDELINES FOR OVERLOAD PROCESSING
1
For the Input – "Refl", "Bridge":
1.1
Reduce the probe drive;
1.2
Perform the probe balance by pressing
key.
2
For the Input – "Single":
2.1
Choose the capacitor by pressing
key;
2.2
Perform the probe balance by pressing
key;
2.3
If the recommendations specified in paras 2.1-2.2 didn`t resolve the
overload, then it is necessary to reduce the probe drive and repeat paras 2.1-2.2.
Lightning of the right overload indicator
(pos. 10, Figure 8) –
indicates
the
general overload of the
input of the receiving circuit. General overload may
include: overload by the input of the receiving circuit (exceeding the maximum
allowed signal amplitude at input of the receiving circuit
),
ADC overload
(exceeding the maximum allowed signal amplitude at ADC input).

For the input – "Refl", "Bridge" and "Single":
3.1
If the left indicator lights, then repeat the steps described for overload
processing for the left indicator (see above);
3.2
If the right indicator lights only, then it is required alternately reduce
the “ PRE AMP” and “ GAIN”. After each gain change it is required to press
key.
