Making Connections to the External Input/Output Terminals
(When using the B-530 option)
Connect the output side of the AC adapter to the connector
indicated as "DC LINE" on the GL900.
Use a flathead screwdriver to push the button above the
ground terminal while connecting the grounding cable to
the GL900. Connect the other end of the cable to ground.
Grounding cable
Caution:The BNC and screw-type terminals of the same channel are connected.
Do not input signals to the BNC and screw-type terminals of the same channel at the same time.
It may cause damage to the measurement device.

Avoid electrical shock and short circuit accidents
• Do not apply voltage of AC33 Vrms or 60 VDC or above between the analog
input section and main unit (GND terminal), or to between each analog
channel.
• Do not apply voltage exceeding the rated voltage to analog input section
(between + and – terminals).
Range 20mV to 1V : maximum 30Vp-p
Range 2V to 500V : maximum 500Vp-p
Warming-up
The GL900 should be allowed to warm up with the power turned on for
approximately 30 minutes to achieve operation according to the specified
performance.
Connection Precautions
Do not input signals to the BNC and screw-type terminals of the same
channel at the same time.
It may cause damage to the measurement device.
Unused channels
The analog input section has high impedance.
If it is open, measurement signals may not be visible due to noise.
In such a case, set input setting of unused channels to "Off" or short circuit
the + and – terminals.
Noise countermeasures
If measured values fluctuate due to extraneous noise, conduct the following
countermeasures.
(Results may differ according to noise type.)
Ex 1 : Connect the GL900's GND to ground.
Ex 2 : Connect GL900's GND to measurement object's GND.
Ex 3 : In the AMP settings menu, set filter to any setting other than "OFF".
Ex 4 : Operate GL900 with batteries (Option: B-517).

Make the settings required for data capture. Here we will make only those settings that are
absolutely necessary. The other settings will be left as the default settings (the settings made
prior to shipment from the factory)
The keys used on the menu screens are the keys, the ENTER key, and the QUIT
key. The current cursor position is displayed in blue. Use the keys to move the cursor.
If you press the ENTER key at the cursor position, a selection menu or a box for inputting
numeric values and so forth is displayed. If you press the QUIT key, the screen closes and
the settings are canceled.
1. Use the keys to move the
cursor to the Input parameter
opposite CH 1 and then press the
ENTER key.
2.A selection menu is displayed
when the ENTER key is pressed.
Use the and keys to select
"TEMP."
3. Press the ENTER key to confirm
your selection.
(Note: Select "DC" for voltage measurement, and "Humidity" for humidity measurement.)
(1)Move the cursor to the Range parameter opposite CH 1 and select "1V".
(2)Make the same setting for CH2.

Points to
Remember !
Internal RAM, Internal flash memory and USB memory can be selected for
Data Capture Destination.
Data can be recorded in the internal RAM at the sampling interval of 10μs or
more, but will be erased when the power is turned off or next capture is
performed. Internal flash memory and USB memory can record at the sampling
interval of 1ms or more for a long period of time (until the medium is full or one
file reaches 2GB).
When data capture starts, auto save starts saving data in the auto save
destination at the same time with the internal RAM. Auto save is
continued in the background even when internal RAM data capture is
finished.

4. Data Replay : How to Replay Captured Data
This completes our simple explanation of how to use the basic GL900 functions.
The GL900 has many other convenient functions. Please see the next five pages for further details.

Timer functions and trigger functions can be used to control the timing of the start of a
data operation, and the timing of the end of a data capture operation.
Timer Functions
Specify the condition as "Enable data capture from 9AM to 2PM every day".
(1) Press the MENU key to open the "TRIG" menu and then set the timer mode to
"Everyday cycle".
(2) Align the cursor with the start side setting and then press the ENTER key to open
the Everyday Cycle menu.
(3) Align the cursor with the time and then press the ENTER key to open the Numerical
Value Setting screen. Set the numerical value to "09" using the cursor and then press
the ENTER key.
(4) Set the stop side setting in the same way to "14".
This completes the timer settings.

Points to
Remember !
Here we will specify the timer condition as
"Enable data capture from 9AM to 2PM
every day", and the trigger condition as
"Start data capture when the CH1 level
exceeds 0.3V". In the left diagram, the
green bar of the timer trigger information
shows the actual data capture.
(You can see the timer trigger information
in the TRIG menu.)
The GL900 is provided with various functions that enable it to be used more effectively.
We have selected three of those functions to describe in further detail.
When the timer mode is set to "Everyday
cycle" or "Every hour cycle", data capture
operation is automatically repeated after
it is started. When the timer mode is set
to the date time setting, data is captured
in one data capture operation.

Trigger Functions
Specify the condition as "Start data capture when the CH1 level exceeds 0.3V".
(1) Press the MENU key to open the "TRIG" menu and then set the Start Source
setting to "Level".
(2) Set the Combination to " Edge OR " .
(3) Set the CH1 mode to "H".
(4) Open the Level Value Settings menu and set to "0.3V" with the cursor, and then
press the ENTER key.
(5) Align the cursor to the button in the level menu settings and press the
ENTER key.
This completes the trigger settings.
Points to
Remember ! Level detects whether or not it is
above or below the set level.
Edge detects when it passes through
the set level.

1. How to Make a Span setting.
The Span parameter is used to adjust the amplitude of the input waveform.
This setting is made in the aforementioned Free Running status.
(1) Adjust the span display width for CH 2 to 0.25V.
(2) Press the SPAN/POSITION/TRACE key to select the SPAN mode.
(3) Use the and keys to make CH 1 active (enlarged display).
(4) Use the and keys to change the Span value. Here we will set the value to 0.25V.
When this setting has been made, the waveform screen scale will be set to "+0.125
to -0.125".
2. How to make a Position setting.
The Position parameter is used to adjust the zero position's upper and lower positions
for the input waveform.
(1)Press the SPAN/POSITION/TRACE key to select the POSITION mode.
(2)Use the and keys to make CH 1 active (enlarged display).
(3)Use the and keys to set the Position value to "+0.25V to –0V".
When this setting has been made, the waveform screen scale will be set to "+0.25V
to -0V".
3. How to make a Trace setting.
The Trace parameter can be used to specify the waveform display of selected channels
as On or Off.
(1)Press the SPAN/POSITION/TRACE key to select the TRACE mode.
(2)Use the and keys to make CH 2 active (enlarged display).
(3)Use the and keys to select Off.
When this setting has been made, the CH 2 waveform is not displayed.
Span, Position and Trace Functions to Adjust the Waveform Display
Points to
Remember !
17
These functions enable you to make adjustments in order to view individual
channels more easily, and to delete waveforms that you do not need to view.
The span, position and trace operations can be performed while the
GL900 is in the Free Running status, while it capturing data, and while
it is replaying data. The changes made are applied to the displayed
data only, and so the original data is not affected in any way.
The currently selected mode (SPAN,
POSITION or TRACE) can be checked
by looking at the "Waveform Operation
Display Area".
