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
• CD-ROM: 1
• LCD protector: 1
• AC cable/AC adapter: 1 set
• Screwdriver for input terminal unit: 1
• 10-channel 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.
Connecting to a PC (the PC is not supplied by Graphtec)

Grounding cable
Always connect the GND terminal and refer to
the safety precautions. The GL450 must be
grounded even when connected to other
devices and sharing a common ground level.
CAUTION
(2) RANGE/SPAN/POSITION key
These settings can be made or changed for each channel individually, even while the
GL450 is in the 'free running' status (not capturing data) or performing measurement.
(4) START/STOP key
Press the [START/STOP] key to select the START status (awaiting trigger). Press it once
again to select the STOP status (free running).
(8) DISPLAY key
Press the [DISPLAY] key to switch through the measurement modes.
(11) CURSOR key
When data is being replayed, press the [CURSOR] key to switch between Cursor A and
Cursor B.
(10) SAVE key
Press the [SAVE] key to save data, to make a copy of the screen, and to save the data
between cursors (only during a data replay operation).
(9) REVIEW key
If the [REVIEW] key is pressed during the Free Running

data is replayed.
If the [REVIEW] key is pressed during measurement,
past data is displayed together with the data currently
being measured in a dual-screen format.
(5) QUIT (LOCAL) key

operations within a setting menu. (If the GL450 is in Remote status, press this key to
cancel the key lock status.)
(6) MENU key
Press the [MENU] key to switch through the detailed setting menus.
AMP (Amplifier settings): This menu is used to make the Input, Range, Filter settings, etc.
ANNO (Annotation settings): This menu is used to set and display comments for each channel.
DATA (Data settings): This menu is used to make the sampling interval and calculation settings.
ALM (Alarm settings): This menu is used to make the alarm and trigger settings.
FILE (File settings): This menu is used for PCMCIA card operations.
I/F (Interface settings): This menu is used to make the USB and TCP-IP settings.
