Page 13: Installation
It is recommended to choose a mounting location with unimpeded airflow. During bakeout ® of the vacuum chamber for achieving very low pressures the JEVAmet IOM should be mounted in a way so that the convection heat of the heated vacuum chamber does not significantly heat up the instrument. -
Page 14: Electrical Installation
Electrical Installation 5.2.1 Rear of the Instrument ® Figure 3, page 14 is showing the rear of the JEVAmet IOM. The pin assignment of the connector as well as the operating and display elements are described in the following chapters. -
Page 15: Operation
Instrument is not ready for operation. The polyswitch fuse has been activated. Disconnect the instrument from the voltage supply and reconnect. If the fuse is activated again there is a failure of the electronics. Please contact JEVATEC. Red blinking Emission error. Automatic deactivation of the emission. -
Page 16: Measuring Mode (Emission)
Measuring Mode (Emission) Start the emission as follows: • Apply LOW level on pin 1 of the input / output connector ( Figure 4, page 14). • The LED “Mode” lights up green. Stop the emission as follows: • Disconnect pin 1 of the input / output connector (... -
Page 17: Degas Mode
The pressure reading serves as an orientation about the cleaning ® procedure but is beyond the accuracy specifications of the JEVAmet IOM. By degassing of the sensor, the contaminations are removed to a large extent. -
Page 18: Maintenance And Service
Contaminated products (e.g. radioactive, toxic, caustic or microbiological hazard) can be detrimental to health and environment. Products returned to JEVATEC should preferably be free of harmful substances. Adhere to the forwarding regulations of all involved countries and forwarding companies and enclose a duly completed declaration of contamination You will find the copy template in the appendix 2 of this manual. -
Page 19: Troubleshooting
If the malfunction persists even after having switched on and off the instrument several times and/or having replaced the sensor, please contact JEVATEC. 7.2.2 Repair Defective products must be sent to JEVATEC. JEVATEC will not assume any responsibility ® or warranty in case the operator or third persons repair the JEVAmet IOM. -
