DGas Mode: CAUTION: BEFORE INITIATING DEGAS, VACUUM MUST BE AT OR BELOW 1x10-7 EXCESSIVE DEGASSING AT ANY TIME CAN DISTORT THE GAUGE ELECTRODES AND CAN RESULT IN A MISLEADING TRANSIENT DECREASE IN PRESSURE INDICATION Degas mode is used to “Degas” or clean the inside area...

IGE 300 Page 13 of 21 The IGE-3000’s filament may be controlled remotely via the D power supply connector by wiring relay contacts or a transistor switch across pins 8 and 9, (refer to section 2.5 /Figure 1 and Figure 3 below). Pin 8 is digital ground and pin 9 is the filament control line. The IGE ...

IGE 300 Page 14 of 21 5. Theory of Operation The functional parts of a typical ionization gauge tube are the filament (cathode), the grid (anode), and the ion collector (refer to Figure 4 below). The IGE-3000 control circuit maintains the grid voltage is maintained at 30 VDC, the grid voltage is mai...

ADVANCE SETUP GUIDE The IGE-3000 has several setup and control commands which can be accessed by using the ADJUST rotary encoder and SELECT push-button while viewing the display. Note that most of the commands, which are described below, can be accessed usi...

IGE 300 Page 16 of 21 6.4. Data Bits/Parity Bits/Stop Bits P8n1 The first character, “8” corresponds to the number of data bits. (e.g. 7 or 8). Second character, “n” corresponds to the parity bit. (i.e. n- no parity, E- even parity, o- odd parity, 0- space, 1- mark) The last character, “1” correspon...
