3 Description
CPM 500 Electronic Peak Pressure Indicator 6
3 Description
3.1 Introduction The electronic indicator CPM 500 is a handy, battery powered,
portable device to measure and evaluate cylinder pressure on
diesel engines at speed up to 1500 RPM.
The CPM 500 collects 10 consecutive pressure measure-
ments (cycles) and calculates peak pressure and engine
speed. The measured data are displayed in numerical format
on the LCD screen and can be stored in memory.
Up to 20 measurement data sets can be stored in the
CPM 500. The stored data can be downloaded via USB-
interface to a personal computer for evaluation.
The scope of supply includes software for Windows which
allows additional evaluation and visualization of the
collected data.
3.2 Measure functions Pmax: average maximum pressure of 10 cycles
Pcomp: compression pressure
RPM: engine speed
A complete individual pressure curve average over the 10
cycles will be stored in the CPM 500 memory with each
measurement.
3.3 Functional description The cylinder pressure will be measured with the CPM 500
unit incl. high temperature pressure sensor at the indicator
cock on marine diesel engines.
Memory : for 20 data sets
Application 2 –stroke: 40 –300 RPM
Application 4 –stroke: 200 –1500 RPM
The battery must be re-charged after approximately one
hour of continuous operation.

4 Operation

4 Operation
4.1 Operator push buttons
Remarks: After switching “On“, the CPM 500 automatically starts in 2-stroke mode. For converting to initial 4-
stroke mode, the user must connect the CPM 500 via USB cable to a powered up PC.
When connected, press “Read“ and “Measure“ simultaneously. The display starts to toggle between 4- and 2-
stroke start mode.
After display of the desired mode, immediately unhand the push buttons to store the selected start mode.
The same procedure can be used for switching from 4-stroke start mode to 2-stroke.

4.5 Charge battery
The CPM 500 has a re-chargeable battery. The battery
charging will start automatically after the CPM 500 unit
has been connected via USB cable from USB port to PC
(fig. 4,5,6,7)
Fig. 4: USB-port of CPM 500
Note: At first usage please connect CPM 500 via USB cable to PC.
Charge battery for 2h continuously without disconnecting from PC !
Fig. 5: CPM 500 connected via USB cable to PC
Fig. 6: Indication during charging process Fig. 7: Indication charging process completed
Do not change battery during charging process while CPM 500 is connect via USB cable to PC.
When the indicator is connected by USB, the battery charging runs automatically. The indicator can detect the
charging status and continues charging until the battery is fully loaded. Then the charging process stops
automatically. It is not recommended to interrupt the charging process before it is automatically stopped. The
charging process is finished when the display message "CPM 500 charging..." has disappeared.
If the battery status is low and the charging process stops after 5-10 minutes, then the user can manually force
the unit to charge the battery for 90 minutes by pressing both arrows + at the CPM 500 unit
for 2 seconds (Forced Charging Mode).
Note: It is not recommended to use the Forced Charging Mode when the battery charge condition is more than
40%, due to the risk of overcharging. Please see chapter 5.2 for a description how to check the charge state.

Note: Please only use re-chargeable battery E-block type “ANSMANN 250 mAh NiMH”
For changing the re-chargeable battery the battery cover on the back side of CPM 500 must be opened
(fig.9,10,11). Do not change battery during charging process while CPM 500 is connect via USB cable to PC.
Fig.8: Battery cover Fig.9: Re-chargeable E-block battery type:Ansmann
Fig.10: Battery installed on backside of CPM 500
Note: If battery of standard NiMh 250 mAh type Ansmann can not be charged or is not available, then the
operator can use for measurements Alkaline battery 9V only for a short time. In this case please immediately
disconnect the CPM 500 unit after transferring data to PC !
4.7 Mounting instructions on marine engines
Measuring at the indicator valve
Before mounting the adapter, please clean the indicator valve by opening (1-2s).
To avoid measurement distortion:
Check adaptor and sensor periodically for dirtiness and clean it if necessary.
+ Pol
The battery should only be installed by
correct pole of battery !
DANGER!
The indicator valve ejects hot gas under high
pressure. Danger of sparks and burning.
Hot gases and particles may be ejected.
Wear gloves and safety glasses!
