Calibration
4-15
5. Change and set the multimeter to DC voltage mode. Connect multimeter to TP7 and TP1 (GND) on
MCB board. Take fluoro exposure and check the voltage is -0.8±0.05V, if not, adjust POT7 on MCB
board, anticlockwise rotation will increase the voltage value.
6. Remove jumper on J5 of MCB board. Take fluoro exposure and check the voltage of TP7 on MCB
is -0.8V±0.05V, if not adjust POT5 on MCB board,clockwise rotation will increase the voltage value.
7. Remove jumper J46. Change and set the multimeter to DC mA mode. Connect multimeter to
TP222 (+) and TP210 (-) on extend board. Take fluoro exposure, check the mA value is 2.1±0.05mA,
if not adjust POT7 on MCB board, clockwise rotation will increase the current. Remove multimeter
and install jumper to J46.
8. If FDB is Rev 10 or higher version (PCB blue printed), perform step 9-11. If not, go to step 12
directly.
9. Set switch J7 to large position and confirm that the light of HL3(FIL_SEL) illuminates.
