JEOL 2010F MANUAL
Quick check list
1. Check the accelerating voltage, must be at 200 kV (right screen), HT (µA) (left panel) at
0.96-0.97 and Emission (left panel) at 155-160.
2. Check the vacuum sequence (left drawer), V17, V13, V5B and V2 on. Vacuum measured
-5
on SIP (SIP unit, second vacuum meter from the top) must be better than 2 x 10 Pa (blue
numbers, 150 l/s). The vacuum in the gun (SIP unit, vacuum meter at the top) must be better
-6
than x 10 Pa.
3. If needed, fill the reservoir with LN2. Be sure that the viewing screen cover is on before
filling the trap.
4. Insert specimen holder into TEM (Insert holder in airlock, set air/pump switch to pump
(yellow light turns ON), when green light turns ON, rotate fully clockwise in two stages and
push in completely)
5. Check the vacuum sequence again, (left drawer), V17, V13, V5B, V8, V21 and V2 on.
Vacuum measured on SIP (SIP unit, second vacuum meter from the top) must be better than 2
-5
x 10 Pa (blue numbers, 150 l/s). The vacuum in the gun (SIP unit, vacuum meter at the top)
-6
must be better than x 10 Pa.
6. If vacuum is ok, open the valve between the column and the gun by clicking button
VALVE (left panel controls).
7. If needed, align the microscope. Work!
