2. Product
2.1 Description
This software is used to display the numerical measurement
data and visualize the pressure curve. The curve shows
the variation in cylinder pressure with time. For clarity
this function is represented in degrees of crank angle,
720 scale graduations corresponding to 360 °. Rotational
irregularities are not taken into account and the curve is
not adjusted for TDC. The software also calculates and
shows on the diagram the mean value of the saved
measurements pmax, pav and pmin.

5. Data Transfer
1. Connect EPM to the PC with the included PC link
cable
2. Start program and display Setup Menu

3. Choose COM interface; the name of the vessel or
system can be entered
4. Display Transfer Menu and follow the instructions in
the Data Transfer box. The progress of the data
transfer will be displayed.

On the Type 2516B... the transfer has to be started
manually
Fig. 6: The progress of the data transfer is displayed
The measurement data (memory block and cylinder
number) are chosen and the data transfer carried out on
the engine peak meter.

5. After the data transfer additional comments can be
entered using the "Measurement Properties" menu.

additional comments on the measurement
If the data transfer fails, please check whether the
correct COM interface has been set and the cable is
properly connected. Take note that only the included
connection (null modem) cable may be used for the data
transfer. Only new firmware supported.
5.1 TDC Shift and Saving Data
After the data transfer, system factors may cause the
pressure curve to be displayed significantly offset on the
x-axis. The curve can be shifted on this axis with the aid of
the "TDC Shift" function.

6. Measurement Presentation
6.1 Choosing Displayed Cylinders
This choice is also made in the main window, by checking
or unchecking the individual cylinders on the selection bar.

6.1.1 Comparing Cylinder Pressure Curves from Measurements over Different Time
Periods
The "Reference" function allows viewing the change in the
cylinder pressure curve over a long period of time. For this
purpose the pressure curves from two measurements can
be compared with one another.
Procedure:
Choose display so that only one pressure curve is shown.
Pressing the "Reference" function button opens a dialog
box for choosing the data files. When the file is opened,
the cylinder pressure curve with the same cylinder number
is shown automatically.
6.1.2 Zooming Curves
To zoom in on the curve, the left mouse button is pressed
and the mouse dragged over the relevant part of the curve.
Double-clicking with the left button cancels the zoom
function.

6.2 Data Table
Clicking the "Data Table" displays all of the numerical
values.

6.3 Cylinder Balancing
This function compares the measurements of each
individual cylinder with the calculated mean saved in the
same memory block. The calculated mean is shown on the
right on the y-axis. A percentage limit for this deviation can
be entered on the Setup Menu.
Fig. 14: "Cylinder Balancing" view
6.4 Bar Charts
The measurements are displayed in the form of bar charts.
If the measured value pav is displayed, the standard
deviation will also be shown on the diagram.
