Features
TFT color touch screen, visible from more than 3 m.:
• Shows RPM and RCF, time, temperature, acceleration/deceleration values (PCBS)
and unbalance location system (ULS).
• Speed programming in 10 RPM/10 xg steps.
• Real RCF values on screen based on accessories configuration.
• Count up/down from “0” or at “set RPM/RCF” for reproducible tests.
• Timer from 1 sec to 99 hours programmable in 1 sec. steps and hold position.
• PCBS: Progressive controlled acceleration and braking system up to 175
selectable ramps that prevents sample homogenization after separation.
• ULS: Unbalance location system indicating on the screen the number of the
bucket which produces the unbalance switch off.
• Start delay: To program the time at which the cycle is to begin.
• Linked program: Permits the linking of up to 8 consecutive programmes without the
need of user intervention.
• 100 programmable memories, with protection under password.
• Several acoustic and visual messages showing the situation of the device to the user.
