Administration & calibration
Customer logins
Nobody can sign themselves up — a lab exists because you created it here, and it arrives active. Expire stops it working on its very next request. Calibrate sets the instrument it owns.
Calibration read-only
These constants belong to the account, not to the install — pick a login above to calibrate it. C2 = (L/10) / ((d/20)·ln(Re/d)): ln(Re/d) is the denominator and Re sits hundredths of a millimetre above d, so a 0.05 mm slip in Re shifts C2 — and the Laray viscosity — by an order of magnitude. ASTM never reads the geometry; only Laray does.
Adverts
Every signed-in operator sees these in the Advert card, newest first — more than one rotates every few seconds. Delete removes the row and its image file.
