Page 11: Switch On/Off The Ba Sensor Filament
When the power supply is switched on, the "Filament" parameter is set to "On", (default setting), i.e. the HPT 200 is operating in normal mode. Status changes of this parameter during operation are stored only temporarily. The status of the "Filament" parameter can be altered at any time and remains stored until the power supply is switched off. -
Page 12: Selecting Switching Range
Operation Selecting switching range Depending on the application, the HPT 200 gauge enables adjustment of the switching range between Pirani and BA sensors to avoid – the set value for pressure control is in the switching range or, – in the case of coating applications, the hot cathode (BA) being switched on and gets prematurely contaminated. - Page 13 Operation Name Data type Handling Correction value 2 - u_real readable, writable (Cold cathode) Parameters are displayed in square brackets as a three-digit number in bold font.

Operation Activate/send parameter for low pressure (control command) Low pressure adjustment (Parameter [P:741/740], Slave device address: "001") ? ASCII ASCII Adjusting the gauge The gauge is factory-adjusted. It may be necessary to adjust the Pirani sensor in the event of contamination, other installation positions, extreme temperature fluctuations, ageing, etc. -
Page 17: Degas
Degas Degas Deposits on the electrode system of the hot-cathode gauge may cause instability in the measuring signal on the one hand and increased degassing in the ultra-high vacuum on the other, which means that too high pressure may possibly be measured. In this case, it is appropriate to clean the sensor anode by outgassing the adsorbed gas particles at a pressure below 2 ·... -
