■ Checks
CAUTION
Before removing the covers, be sure to turn OFF the high-voltage switch. If the machine is
powered ON with any of the covers removed, the photomultiplier will be damaged.
(1) Remove the following covers.

(7) Type in the number of MZ1 (FFM).
(8) Set up an operation parameter as instructed by the onscreen message.
➮ MZ1 operation starts.
(9) Measure the voltage between OK and 5G on MZ1.
(10) Select “3. STOP”.
➮ A list of sensor Nos. is displayed.
(11) Type in the number of MZ1 (FFM).
➮ MZ1 stops.
(12) Change the operation parameter for MZ1 at step (7) as follows, and repeat steps (5)
through (10).
• Rotation in normal direction
• Rotation in reverse direction
If MZ1 rotates for all of the operation parameters and the voltage between OK and 5G
on MZ1 is less than 1 V, then the check is completed.
If MZ1 does not rotate or the voltage between OK and 5G on MZ1 is greater than 1 V
for any of the operation parameters, then check the SLC08A board.
