3、 Instrument and Meter Operation for 24 New Standard Aggregate Robustness Test Device

①Firstly, according to the specifications, prepare the solution in the insulated bucket. Set the 'immersion temperature gauge'22℃.“Lift frequency table”Factory set, no need to set.“Soaking schedule”setting20hour(The dialer is1959)press“power switch”and“heating switch”.

②at this moment“Immersion temperature gauge”Start working, other instruments do not work, when the temperature reaches25℃The rear instrument automatically enters the lifting state, at this time“Lift frequency table”Start thanking 25Secondary lifting cycle, automatic conduction after cycle completion "soaking schedule”When it comes to insulation20Stop the machine after hours and the instrument will sound a beep alarm.

③When entering the next cycle, it will“Soaking schedule”set as8hour(The dialer is0759) (Ready to dry4Soak for hours)press“Reset key”Restart. When drying4Second soaking per hour4Hour by hour1-2Completed next time. When entering the next cycle, refer to this section for the subsequent cycles.
