MAIN SPECIFICATIONS
2.1
Range of operating frequencies adjustment – from 10 Hz to 16 МHz.
2.2
Setup of the max. sampling frequency/digitizing rate –
10 kHz/10000 samples per second (max).
2.3
Setup of the range of adjustment of ECP excitation signal voltage
(double amplitude) – from 0.5 to 6.0 V.
2.4
Preamplifier adjustment – from minus 6 to plus 40 dB with a step of
0,1; 1; 10 dB.
2.5
Gain adjustment – from 0 to 30 dB with a step of 0,1, 1 and 10 dB.
2.6
When displaying the signal in a complex plane it is possible to have
the following variants: а) the complex plane center is situated in the center of
display area; b) the complex plane center is situated in the left upper corner;
c) the complex plane center is situated in the right upper corner; d) the
complex plane center is situated in the left bottom corner; e) the complex
plane center is situated in the right bottom corner; f) all frequencies and
mixtures are displayed on the same page (when operating in dual-frequency
mode); g) manual adjustment of the positioning of the center of the complex
plane.
2.7
There is automatic LED and sound flaw alarm (ALARM) in the flaw
detector.
2.8
In processing of the testing results the flaw detector provides the
following options:
−
changing of ECP signal phase (the range of signal turn – from 0° to
360° with a step of 0.1°; 1°; 10°);
−
filtering of ECP signal (there are 5 types of filters: Averaging,
Differential, Low-pass, High-pass, Bandpass);
−
formation of a mix of two frequencies (for combining an operator can
select one of 4 algorithms: summation, subtraction, summation with
horizontal inversion, summation with vertical inversion).
2.9
Time of continuous operation of the flaw detector from fully charged
storage battery – no less than 8 hours.
2.10
Average mean time between failures – no less than 40000 hours.
2.11
Defined no-failure operating time – 4000 hours.
2.12
Total average service life – 10 years. The criterion of marginal
state of the flaw detector is economical inexpediency of restoration of its
performance by repair.
2.13
The flaw detector is powered from the in-built storage battery
with rated voltage of 12 V.
2.14
Weight of the flaw detector with a storage battery (without ECP
set, cables and casing) – no more than 0.9 kg.
2.15
Overall dimensions of the flaw detector – no more than
230 mm
135 mm
98 mm.
