  1. Pre-insertion Check (TEM Main Body)
    1. Specimen holder is not inserted
    2. [TEM Center: Upper menu] Control → Beam
      • Display Beam Controller (for JEM Administrators)
      • Check accelerating voltage and emission
    3. [TEM Center: Upper menu] View → Valve/Vacuum Monitor
      • Display Valve/Vacuum Monitor
      • Check vacuum level
    4. [TEM Center: Upper menu] View → Condition Monitor
      • Display Condition Monitor
      • Check alarms
    5. [TEM Center: Upper menu] Control → Aperture
      • Display Aperture Panel Controller
      • Retract the in-gap objective lens aperture
      • Select [OPEN] in Hole Diameter Select
    6. [TEM Center: Left side TEM System Task Bar] Stage
      • Check stage position and tilt
  2. Pre-insertion Check (Specimen/Holder)
    1. Specimen check
      1. The specimen is correctly fixed and does not move.
      2. No adhesion of sebum, dust, etc., near the specimen.
      3. Ion cleaning has been performed if necessary.
    2. Holder check
      1. The tip of the holder is not damaged or deformed.
      2. No dust is attached to the O-ring. No scratches.
      3. (For 2-axis holder) Y tilt is 0.
        1. Check both the value on the TEM center and the actual stage tilt
  3. Holder Insertion
    1. Hold the holder handle and the front of the O-ring with both hands, align the guide pin, and insert it straight into the goniometer.
      1. Push it in until it stops, keeping your hand on it.
      2. At this position, the insertion detection switch operates. (It will be released if rotated, so do not move your hand)
    2. Goniometer: Switch the PUMP/AIR switch to PUMP.
      1. The specimen pre-chamber is evacuated.
      2. Wait until the green lamp lights up and PiG4 becomes EvacReady (green).
    3. Insert the holder
      1. Turn the holder clockwise (slightly). (Until it stops)
      2. The holder is drawn in. (Slightly)
      3. Turn the holder clockwise (largely). (Until it stops)
      4. The holder is (largely) drawn in. (Do not let go until it stops)
      5. (For 2-axis holder) Connect the cable for Y-axis tilt.

    4. Select the holder
      1. When the holder is inserted, the Specimen pane is displayed.
        • [TEM Center: Upper menu] Control → Specimen
      2. Select the inserted holder from the Specimen Holder drop-down list.
      3. Click the [OK] button
        • Since the movement and tilt range of the stage differs for each holder, be sure to select the inserted holder.
    5. Wait for the vacuum to recover
      1. Penning Gauge 20 or less
      2. SIP 10^-5Pa range
