The reading for the VT has been fixed, so you can view the temperature at the probe via the Topspin software using “edte”
However, the Facility Managers are still looking into the other issue of the VT settings changing between 298 K and 280 K without user input. Please always check the temperature with edte before putting your sample into the magnet.
variable temperature unit does not work, gives an error. Cannot determine temperature of instrument
