[RASMB] Xl-I wavelength check question

[Mark Agacan]

I have a question regarding the wavelength accuracy check for the XL-I:

Using a windowless cell (aluminium cell housing only with no centerpiece or windows, or one of the empty holes in the rotor?) - how can I match the weight of this cell with the counterbalance, even at the relatively low speed of 3000 rpm?

The remainder of the procedure as outlined in the Troubleshooting and Maintenance section of the XL-I manual seems straighforward enough, i'm just a little unclear on exactly how to load the rotor for this measurement.

Best Regards

Mark
