1.2 EMO and POWER Switches
The EMO (emergency stop) and POWER switches are located on the right-hand side of the
prober’s front panel.
If an abnormality is observed during the operation of the loader, the chuck or the optional HF
test head manipulator, press the EMO switch. Power supply to the prober will be shut off
immediately, and all moving parts will be stopped (the ON switch lamp will dim, and the OFF
switch lamp will be lit). To recover from this power down status, unlock the EMO switch by
rotating it in the clockwise direction. This will re-enable the POWER ON switch.
When the OFF switch lamp is lit, pressing the ON switch will light the ON switch lamp and
supply power to the prober. Press the OFF switch to turn off the power. The ON switch lamp will
dim and the power supply will be shut off.
