Interface Design
All functions of the instrument are started from the main menu interface.
The main menu contains five sub-modules: setting, deleting, sampling, viewing, and shutting down.
2.1 Sampling Interface
In the main menu interface, select the sampling icon， Press the **ok**key to
enter the sampling interface.
Sampling interface button c key Pop-up Menu as shown in the figure， The
first item is to delete the last rebound value; the second item is to set
parameters; the third item is to exit sampling， At this time, press the
c key to return to the sampling interface to continue sampling .
Press the key to select the second item， Press the ok key to enter the
sampling parameter setting interface.
The sampling parameter setting menu includes continued sampling, number of
measuring points (American Standard and European standard are not allowed to
be modified), carbonization value, Impact Angle, detection surface, Allowable
minimum, and maximum.
Press the c key on the sampling parameter setting interface to return to
the sampling interface.
After the completion of sampling, the system alarms and automatically jumps to
the sampling completion interface. The component data is saved. Press the
c key to switch to the sampling selection interface. Select continue
sampling or modify parameter sampling by key. At this time, press the c
key to return to the main menu interface.
2.2 System Setup Interface
Select the Settings icon in the main menu interface, press the ok key to
enter the system setting interface. There are 7 options. They are backlight
delay, unit, system time, curve, voice switch, age, a Correction factor of
test block size.
Backlight delay can be adjusted by key, and the range is the 20s-80s.
Compressive strength units: MPa, psi, and kg / cm².
Select the time icon, press the ok key to enter the system time
adjustment interface. When adjusting the time, press the key to select the
part to be adjusted. Press the key to adjust the value.
After adjustment, press the c key to return to the system setting
interface.
Curve Settings can be selected as JGJ23-2011, ASTM C 805, EN 12504-2, and
custom curves. If set as a custom curve, the maximum number of sampling points
can be set to 400 during sampling.
Need to slow down the Recoiling speed when the voice is turned on.
There are two options for age: 7 days and 14-56 days.
There are three correction factors of test block size according to different
sizes:1.0, 0.95, and 0.8. After the calculation, the strength value is
corrected.
2.3 Deleting Data
After the delete icon is selected in the main menu interface, Press the
ok key to enter the deletion confirmation interface.
Once this command is executed, all component data in memory will be deleted
and cannot be recovered. For the sake of insurance, The instrument will be
confirmed by a confirmation screen, so be careful!
2.4 Viewing Interface
After the view icon is selected in the main menu interface, press the ok
key to enter the viewing interface.
The viewing interface is the same as the sampling completion interface. The
third item in the status bar of the interface is the number of current
components.
Press the key to increase or decrease the number of current components, in
order to view all component data.
Press the ok key in the viewing interface to select the carbonization
depth value.
Press the key to change the carbonization depth value.
Press the **c** key in the viewing interface to return to the main menu
interface.
2.5 Shutting Down.
After the shutdown icon is selected in the main menu interface.
Press the ok key and the system will prompt to shut down. If you forget
to shut down, the system will shut down automatically after the shutdown
delay, and give an alarm prompt. Press any key at this time to cancel the
