      Unit Operation Checks 9. PCB ASSY, IG CTRL-A Outline IG CTRL-A lights the ion-gauge measurement bulb (IG bulb) filament and generates the grid voltages. The MAIN CTRL-A PCB offers the functions to measure the collector current to determine the degree of vacuum. When the filament lights, thermoelectrons are discharged toward a grid held at a potential of +150V, resulting in a current from the grid to the filament (grid current).

  • Page 97   3. Checking the grid and filament voltages Turn IG on with the tool program and measure the grid and filament voltages (CP4[GRID], CP5[FIL-], CP3[FIL+]). These voltages can also be measured at the IC bulb connector. Check the grid. Voltage across CP4[GRID] and IG bulb, Pin 4 = 15010±V Pull out the IG connector if V is abnormal.

In this case, turn VR1 while monitoring the low mass numbers m/z18 and m/z28 to obtain equal peak amplitudes. If this adjustment is not possible even by fully turning VR1, switch JP1 and attempt the adjustment again.
