•
There two mounting slots for the SD memory card, and long-term measurement can be performed while
•
backing up the data.
* When the optional wireless LAN unit is installed, the SD memory card cannot be inserted into the SD
CARD2 slot.
Because disk image can be used for the SD memory card , multiple data can be saved.
•
The new ring memory capture function maintains latest data even after capturing for a long term. (You
•
need to set how long you want to keep data.)
For voltage, temperature and humidity measurements, data can be captured at sampling rates of up to
•
10 ms per channel by using fewer measuring channels. (Temperature measurement can be done at
sampling rates of 100 ms and higher.)
The GL240 is equipped with the relay recording function, and 2GByte or more data can be saved by
•
switching the to the other le without data missing. (When the capacity of one le reaches 2GByte, the le
is switched.)
Data Control & Processing
The application software provided lets you set conditions and monitor data on on a computer using the
•
USB interface.
The application software allows you to control multiple GL240 units from a single computer to easily
•
perform multi-channel measurements.
The USB drive mode function enables the SD memory card to be recognized as an external drive by the
•
PC.
(Connect the GL240 to the PC and turn on the GL240 power while holding down the [START] key.)
Captured data can be read from the application software to les and displayed for processing.
•
When optional wireless LAN unit is installed, the data capture can be performed remotely by controlling
•

1.4 Notes on Temperature Measurement
Please observe the following precautions when performing temperature measurement.
Do not block the air vents. Always provide a space of at least 30 cm on all sides of the GL240.
•
For stabilized temperature measurement, allow the GL240 to warm up for at least 30 minutes after turning
•
it on.
Exposure of the input terminals to direct drafts, direct sunlight, or abrupt changes in temperature may
•
impair the equilibrium of the input parts and result in measurement errors. To measure temperature in
such an environment, take appropriate countermeasures such as changing the installation site of the
GL240.
To conduct measurement in noisy environments, connect the GL240’s GND terminal to ground (Refer to
•
“2.15 Noise Countermeasures”.).
If measured values uctuate due to noise, set to a slower sampling speed (Refer to “(2) DATA setting” in “3.4
•
Setting Menus”.).
1.5 Notes on Using the Monitor
The monitor is an LCD display unit, and so the display will vary depending on the operating environment.
If the screen saver function is used, it will operate and clear the screen if no operations are performed
during the preset time. If the screen saver operates, press any key to restore the display.
Condensation may form on the LCD screen if the GL240 is moved from a cold to a warm location. If this
•
occurs, wait until the LCD screen warms up to room temperature.
The LCD screen is manufactured to extremely high precision. Black dots may appear, or red, blue, and
•
green dots may not disappear. Likewise, streaks may appear when viewed from certain angles. These
phenomena are due to the LCD screen construction, and are not signs of a fault.
1.6 Changing the Display Language
You can choose the language displayed on the screen. The default display language is set to English when
the GL240 is shipped overseas. To change the display language, see the instructions in "OTH (OTHER
menu :Language".
