GL450 Quick Start Guide
This Quick Start Guide is an easy operation guide that provides explanations on
preparations prior to measurement, basic measurement procedures, and menu operations,
for people who want to start measurement operations right away. Please refer to the
User's Manual for more detailed explanations.
Checking the Outer Casing
After unpacking, check the GL450's outer casing before use to make sure that there are
no surface scratches or other flaws such as stains or dirt.
Checking the Accessories
• Quick Start Guide: 1
• LCD protector: 1
• Screwdriver for input terminal unit: 1
Checking the AC Line Frequency
Set the AC line frequency (50 Hz or 60 Hz) in the "OTHR" menu. Using the appropriate set-
ting is effective in eliminating line noise.
