The display will turn on. Upper line (
Set
) shows time, speed and temperature
set earlier. Lower line (
Actual

according to the temperature set in the upper line). The time of temperature
stabilisation depends on the initial temperature.

PST-60HL:
Place microplates on the platform and fix it with the special
push-down clip by pressing it against the plate covers.
PST-60HL-4: Unscrew the fixation screws. Place microplates on the
