VI Data query
Click the "Data Query" button to enter the historical data viewing interface. This item is divided into
four parts: "test record", "test data", "graphic analysis" and "storage printing", which are basically the
same as the interface after the test is completed.
The "test record" contains the test result number, time, test product information, test personnel and
test parameters;
"Test data" includes the same period, three-phase synchronization, opening / closing time, rigid
opening / closing speed, maximum speed, average speed, opening distance, overtravel, total stroke, coil
current, coil resistance, and phase Information such as bounce time and number of bounces.
The "graphic analysis" includes the 12-way fracture bounce curve, the displacement curve of the
test fracture, and the coil current curve. And by selecting specific t1 and t2 values, the average speed in
the specified motion interval can be obtained. The specific operations are as follows:
In the initial state, the background of the value display areas of t1 and t2 are white. Clicking on any
one of the white areas will change the background color (the background color of t1 becomes pink and
the background color of t2 becomes light green) and the same color light will be displayed Ruler. At this
time, click the color change area again to manually enter the time (less than or equal to the test duration
value) or click anywhere on the display area of the bounce curve and displacement curve, and then move
the cursor ruler to select the specified time scale. During input or movement, t1 / t2, S1 / S2, I1 / I2, will
dynamically display the time, displacement value and coil current value of the cursor ruler,
△
t and
△
S will
dynamically display the time and displacement difference of the selected position ,
V
is the average speed
in the time interval between t1 and t2. The calculation formula is::
△
t=|t1-t2| Unit ms;
△
S=|S1-S2| Unit mm;
V
=
△
S/
△
t Unit m/s;
"Stored print" can optionally print test data or data or graphics in graphic analysis, and can save the
current data to a USB storage device, so that the data can be analyzed by supporting software on a PC.

The “brightness adjustment” and “time calibration” in the main interface can be operated according to
