4.2.3 The connector LINE is intended to connect the cables in MEASUREMENT mode
(see issue 6.3).

.2.4 A “COORD”. grip is used only in the MEASUREMENT mode for the TDR-TA3.3T
output resistance and the wave resistance of the researched cable coordination. The
minimal magnitude of the amplitude of multiple resampled signals is the most appropriate
coordination criterion. It is recommended to use the buttons
«
» and «
» with the
“COORD.” grip at the same time due to obtain the maximal image frequency (see issue
6.4.6).
4.2.5 The
“PULSE” button is used for a quick transition to the “PULSE” selector (see issue
6.4.1).
4
.2.6 The “WINDOW” button is used for a quick transition to the “Window” selector, for a
measurement window (subrange) adjustment (see issue 6.4.2).
4.2.7 The
“LIGHT” button is used for a quick switching on/off of the device display’s
lightning (see issue 6.12).
4.2.8 The
“GAIN” button is used for a quick transition to the “Intensification” selector, for
the gain factor adjustment (see issue 6.4.3).
4.2.9 The
“OFFSET” button is used for a quick transition to the “displacement” selector
due to adjust the vertically offset of the waveform chart (see issue 6.4.4).
4.2.10 The
“Coefficient of shortening” («КУ») is used for a quick moving to the “Coefficient
of shortening” selector due to adjust the coefficient of shortening (see issue 6.4.5).
4.2.11 The
«
» button is used to move a measurement window (subrange) to the
beginning of measurements (see issue 6.9).
4.2.12 The
«
» button is used to give a currently located cursor a zero distance (see
issue 6.8).
4.2.13 The
«
» in MEASUREMENT mode selects the memory menu mode, points:
“EXIT” – exit from function, “Exit from memory” – waveforms exit from the memory (the
“memory” title appears in the right corner), “To memory” – saving a current waveform to
the memory.
4.2.14 The
«
» and «
» buttons in MEASUREMENT mode is used to adjust the signal
amplitudes on the screen, for a vertical offset of the chart, to adjust of the probe pulse
