First Start-up

Steady state

After switching on, the Lorrca Maxsis needs to warm up.

Osmoscan: 5 minutes

Oxygenscan: 1 hour (see also pO2 calibration chapter)

It is recommended to keep the instrument steady state within series of experiments.

Before the instrument can be operated, you have to carry out the following checks and procedures:

Switch ON the instrument. Start-up the PC. Choose LoRRca software program. Select <Hardware check>. Move the Bob down.
Choose <Camera> Set camera gain at 250. Close the hood.
Check the image: OK: The instrument is now ready.

Not OK: Misaligned Check position of the projection screen.
Alignment of the projection screen: Use the hexagon key 2mm to loosen the projection screen holder.
Align the projection screen until the black dot on the screen is aligned with the laser spot. Note: The projection screen holder itself can also be adjusted (equipped with slotted holes) Tighten the screws of the projection screen holder.
Not OK: Driver failure. Update the camera driver. See Camera driver installation
Choose <LoRRca IO><Rinse cup> and confirm. The tubes are being filled. Dry BOB and CUP. Do not scratch the cup and do not touch the glass with your fingers to prevent staining! Pay attention to the hole in the BOB.

After this procedure, the instrument is in the start position for Osmoscan, for Oxygenscan additional steps are required, see Hardware pO2.
