Precautions to Observe When Performing Measurement
Maximum input voltage
If a voltage exceeding the specified value is input, the semiconductor relay in the
input section will be damaged. Never input a voltage exceeding the specified value
even for a moment.
< Between +/– terminals(A) >
• Maximum input voltage: 60Vp-p (Range of 20mV to 1V)
110Vp-p (Range of 2V to 100V)
< Between input terminal/input terminal (B) >
• Maximum input voltage: 60Vp-p
• Withstand voltage: 350 Vp-p at 1 minute
< Between input terminal/GND (C) >
• Maximum input voltage: 60Vp-p
• Withstand voltage: 350 Vp-p at 1 minute
Warming-up
GL240 requests to have approximately 30 minutes warm-up in order to have the
specified performance.
Unused channels
The analog input section has high impedance.
If it is open, measured value may vary due to noise.
In such a case, set to "Off" unused channels in the AMP setting menu or short 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 GL240's GND to ground.
Ex 2 : Connect GL240's GND to measurement object's GND.
Ex 3 : Operate GL240 with batteries (Option: B-569).
Ex 4 : In the AMP settings menu, set filter to any setting other than "OFF".
Ex 5: Set the sampling interval which enables GL240’s digital filter (see table below).

4. Press the [MENU] key and open the "DATA" menu.
5. Set the sampling interval to "1s".
Move the cursor to "Sampling" and then select "1s".
6. Set the Data Capture Destination to "SD memory card".
Here the "TEST" folder is created in the internal memory (SD1), and then
destination for the captured data is set to the TEST folder.
(1) Move the cursor to the File Name parameter and then press the [ENTER]
key.
(2) The data saving destination box shown in the following screen opens.
In the data saving destination box, set the SD1 as a capture destination.

Points to Remember
Data can be replayed while being captured by pressing the [REVIEW] key.
Data can be replayed during the data capture operation from the beginning to the point that
has been captured.
During the replay, you can check arbitrary level values and such by moving the cursor.
You can return to the data capture screen by pressing the [REVIEW] key again.
* When the [DISPLAY] key is pressed, you can switch between the 1-screen and 2-screen.

4. Data Replay : How to Replay Captured Data
Since the data capture has been completed, let's replay the captured data.
The captured file is saved in the “TEST” folder of the internal memory (SD1) that
has been set in the “2. Setting” .
Because the file name is automatically assigned, the file, for example
“20150201-123456.GBD” is created in GBD-formatted file ((Year)(Month)(Day) –
(time).GBD).
The (Year)(Month)(Day) – (time) is the time that you start the data capture.
Explanation of basic operation in the GL240 is completed.
The GL240 has many other convenient functions. Please refer the next five pages for
details.
1. Selecting a file to replay
(1) Press the [REVIEW] key.
(2) Since the file you want to replay has the file name that was appended
automatically when the data was captured, move the cursor to the [OK]
button and then press the [ENTER] key.

(3) Quick settings
(4) Time display
(5) Cursor
2. Replay screen
(3) The Replay screen opens.
Press the [QUIT] key to end the data replay operation.
A confirmation message is displayed. Press the [ENTER] key.
Data replay ends, and the GL240 goes into the Free Running status.

Desired level values and time can be checked by
moving the cursor.

The GL240 has various functions that enable it to be used more effectively.
The selected three functions are described with details in the following.
Here data capture is started in the condition as "Start data capture when the
CH 1 temperature exceeds 20ºC".
(1) Press the [MENU] key and open the "TRIG" menu.
(2) Move the cursor to "Start Source" and select "Level".
(3) Press the [ENTER] key according to the “Level Settings” . The “Trigger
Level Settings” screen is displayed. Move the cursor to the "Mode"
parameter for the CH1, and then select "Hi".
1. Starting data capture
Trigger functions can be used to control the timing of the start of a data
capture operation, and the timing of the end of a data capture operation.
Convenient Functions
Trigger Functions to Control Data Capture Start/Stop Operations
Points to Remember
For example...
The trigger function performs operations such as the following:
• Start data capture when the voltage exceeds 1 V
• Stop data capture at 1:00 pm
• Perform control via external input
16

(4) Move the cursor to the "Level" parameter next to the "Mode" parameter
and then press the [ENTER] key.
(5) The input box shown in the following screen is displayed. Select "20".
Use the and keys to move to the cursor to the second digit from the
right, and the and keys to change the value. Press the [ENTER]
key.
(7) The screen returns to the TRIG menu screen. Press the [QUIT] key to
return the GL240 to the Free Running status.
(8) Press the [START/STOP] key to start data capture.
If the trigger condition has not been satisfied, the GL240 goes into the
"Armed" status as shown on the following screen.
(6) When the screen changes to the following screen, move the cursor to the
button and then press the [ENTER] key.
When the trigger condition is satisfied, the data capturing is started.

1. Starting data capture
Trigger functions can be used to control the timing of the start of a data
capture operation, and the timing of the end of a data capture operation.
Span, Position and Trace Functions to Adjust the Waveform Display
Points to Remember
The span, position and trace operations can be performed while the GL240 is in
the Free Running status, while it is capturing data, and while it is replaying data.
The changes are applied to the displayed data only, the change is not affected
to the captured data.
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) Set the displayed span for CH 2 to 100ºC.
(2) Press the [SPAN/POSI/TRACE] key to select the SPAN mode.
2. How to make a Position setting
The Position parameter is used to adjust the position of displayed waveform
that is set by the upper and lower values.
(1) Press the [SPAN/POSI/TRACE] key to select the POSITION mode.
(2) Use the and keys to make CH 2 active (enlarged display).
(3) Use the and keys to set the Position value to "+80.0ºC to -20.0ºC".
When this setting has been changed, the waveform screen scale will be
set to "+80.0ºC to -20.0ºC".
(3) Use the and keys to make CH 2 active (enlarged display).
(4) Use the and keys to change the Span value. Here the value for
span is set to 100ºC.
When this setting has been changed, the waveform screen scale will be
set to "+100.0 to +0.0".
Points to Remember
The currently selected mode (SPAN,
POSITION or TRACE) can be checked by
looking at the "Waveform Operation Display
Area".
3. How to make a Trace setting.
The Trace parameter can be used to specify the selected waveform to be
visible or invisible on the display.
(1) Press the [SPAN/POSI/TRACE] key to select the TRACE mode.
(2) Use the and keys to make CH 1 active (enlarged display).
(3) Use the and keys to select Off.
When this setting has been changed, the CH 1 waveform is not
displayed.
