Power Up & Self Test  
 
1.  Connect the power cord 
to the power socket. 
2.  Turn the external power 
switch on. 
3.  Hold the power button 
on the front panel to 
turn on the power.  
The power button turns 
green from red (standby). 
Ensure that the power outlet has a ground socket. The 
power outlet will have a ground connection if it is a 3 
socket type. 
Upon turning on, the Mainframe will perform a 
self-test. The self-test checks the System, followed 
by any attached channels.  
When the firmware version of the mainframe and the 
slave are not identical, a message “The firmware will 
be updated, please access to website 
www.gwinstek.com to confirm the firmware version.” 
will appear on the mainframe.
