the menu.
NOTE: If the device exceeds the full scale value, the result will start
flashing.
It is enough to calibrate a single unit for all other units except Bar unit.
The device will translate this calibration for other units.
3. BUTTONS
ZERO: When this button is pressed, the device output is reset. This
button has two different functions as "Up-arrow" and "Zero". The up-
arrow function is used when changing options in the menu. The "Zero"
function is only required during calibration. "Unloaded state" is required
when calibrating. When the unloaded state is defined for the device, the
user must apply pressure slowly to a load cell to find the nearest point to
the zero point. At this pressure point the user presses the "zero" button
of both the device and the load cell and defines this pressure point as
zero for both. This is some kind of fine tuning.
Unloaded state: No pressure load on the device.
PEAK: When this button is pressed, the device will show the maximum
pressure point at that time. For example; Assume that we make a
pressure measurement as in Figure 1 and press the peak button at
different times.
First time interval (A-B): The measurement results are increasing in the
first time interval. So, whichever point in this region is pressed on the
peak button, our maximum measurement will be the last measurement
we made. However, the result at point B has begun to decrease.
Second time interval (B-C): Starting from point B until the point at which
the pressure has passed, the pressure value at the maximum measured
value B in this range will be.
Third time interval (C-D): The area between C-D is the same as the
whole procedure A-B. By the way, our maximum measurement will be
the last measurement we made.
Fourth time interval (D-E): The pressure will remain at the maximum
measured value D at the pressure point D until the last time.
