System mode covers the Display Set, Buzzer, 
Interface, Control, System Time, Data Initialize, 
Information, Statistics, USB Disk and 
CONTACT CHK settings. These settings are 
system-wide and applied to both MANU and 
AUTO tests. 
When the tester is in READY status of MANU 
or AUTO test, it is ready to begin testing. 
Pressing the START button will begin testing 
and put the tester into TEST status. Pressing the 
AUTO key will change from MANU – READY 
status to AUTO – READY status and vice versa.
