1.1. Safety Instruction

This device has been designed and tested in accordance with the relevant safety regulations for electronic devices. However, its trouble-free operation and reliability cannot be guaranteed unless the standard safety measures and special safety advice given in this manual is followed when using the device.

1. The system must only be operated by trained and authorized personnel who know

the manual and can work according to them! 2. Trouble-free operation and reliability of the device can only be guaranteed so long as

the device is not subjected to any climatic conditions other than those stated under ―11 Specifications‖.

3. The CPC2000 always has to be handled with the care required for an electronic precision instrument (protect from humidity, impacts, strong magnetic fields, static electricity and extreme temperatures, do not insert any objects into the instrument and its openings). The device and sensors must be handled with care (don‗t throw, hit, etc.). Protect plugs and sockets from contamination.

4. If the device is moved from a cold to a warm environment, condensation may cause the equipment to fail. You should therefore ensure the device temperature has adjusted to the ambient temperature before trying to switch it on.

5. If the instrument is to be connected to other devices (e.g. via serial interface) care must be taken when designing the equipment connections. It is possible that internal wiring within the external device (e.g. connection of GND to earth) may cause excessive voltages which could harm or destroy the instrument or other connected devices.

6. The mains plug of the CPC2000 must always be accessible when connected to a power outlet, i.e., you must be able to pull the plug from the power outlet without difficulty, at any time.

If the device is operated with a faulty mains power supply (e.g. short circuit from mains voltage to output voltage) this could result in dangerous voltages at the device (e.g. at the sensor socket or serial interface)!

7. Significant electromagnetic radiation can adversely affect the measuring signal of the

CPC2000 or even disrupt the display of the signal completely.



8. The display window behind the plastic film is made of glass (which can splinter). If there is a possibility that this glass incl. the plastic film might break during operation, anyone in the close vicinity of the equipment must wear eye protectors, both before and during operation.

9. Test and calibration assemblies must always be constructed and also dismantled in an unpressurised state (atmosphere).

10. If the CPC2000 comes in contact with oil (which is forbidden), then subsequent use with fuels or gases is strictly prohibited, since this could cause an explosion and risks harm to both people and machinery.

11. If the equipment is damaged and might no longer operate safely, then it should be taken out of use and securely marked in such a way so that it is not used again.

Operator safety may be at risk if:

There is visible damage to the device. The device is not working as specified. The device has been stored under unsuitable conditions for an extended period of

time. If there is any doubt, please return the device to the manufacturer for repair or maintenance.

12. Customers must not attempt to alter or repair the device themselves. Please return the device to the manufacturer for any repair or maintenance.

6. Re-calibrating and servicing

We recommend having the system re-calibrated by the manufacturer at regular intervals of approx. 12 months. Every re-calibration at the factory also includes a comprehensive and free checking of all system parameters. During the first re-calibration a service file is started automatically in which every re-calibration and all extra services are recorded. The instrument requires almost no maintenance, because all parts which are moveable are extremely robust. There are no parts which have to be serviced by the user. During each re-calibration the functioning of all components is checked and changed if necessary. To clean the membrane keypad and the display, use only customary plastic or glass cleaning agents in compliance with the guidelines of the manufacturer. Use cloths which are not prone to generate fluffs.

Before cleaning the surface of the instrument, it has to be made sure that it is not pressurized, the power is switched off and the power supply is disconnected.
