Guidelines for Overload Processing
4.6.1
For the Input
– "Refl", "Bridge":
4.6.1.1
Reduce the probe drive;
4.6.1.2
Perform the probe balance by pressing
key.
4.6.2
For the Input
– "Single":
4.6.2.1
Choose the capacitor by pressing
key
4.6.2.2
Perform the probe balance by pressing
key;
4.6.2.3
If the recommendations specified in paras 4.6.2.1-4.6.2.2 didn`t resolve the
overload, then it is necessary to reduce the probe drive and repeat paras 4.6.2.1-
4.6.2.2.
Lightning of the right overload indicator
(pos. 10, Fig. 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).
4.6.3
For the input
– "Refl", "Bridge" and "Single":
4.6.3.1
If the left indicator lights, then repeat the steps described for overload processing
for the left indicator (see above);
4.6.3.2
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.
