When using temperature and humidity sensor (GS-TH) and the GL840 at the same time, the
operating environment of GL840 is applied.
Temperature and Humidity Sensor (GS-TH):
•
• Humidity sensors measure the change in dielectric capacity of water adsorption. As a result, humidity
from organic materials such as ne particles or exhaust gas may have an effect on the sensor. Use
in environments with large quantities of these organic materials may lead to signicant measurement
inaccuracies.
CO2 Sensor (GS-CO2 ):
•
• Because exhaled CO2 may have an effect on the sensor readings, do not use the sensor to take
measurements near the face.Additionally, should air ow to the sensor be blocked, it will result in
inaccurate readings, so be sure to keep vent holes open.
Illumination / Ultraviolet Sensor (GS-LXUV):
•
• When measuring illumination or ultraviolet light that can have harmful effects on the eyes or skin, be
sure to use protective eyewear, shielding, etc.
• If the sensor becomes dirty, it may affect measurements, so wipe it with a soft cloth when it becomes
dirty.
• Take care to avoid cracking the sensor when handling it. If the sensor is damaged or cracked it may
affect measurements, so replace the sensor.
Others
•
• Depending on the usage and operating environment of Temperature and Humidity Sensor (GSTH), CO2 Sensor (GS-CO2), and Illumination / Ultraviolet sensor (GS-LXUV), it is recommended to
replace periodically the sensor with new one because the sensor performance may be deteriorated.

CHAPTER 1 General Description
1.1 Overview
The GL840 is a compact, lightweight, multi-CH, and multi-purpose data logger with a 7-inch color display.
20CH measurements are available with the standard terminal or Withstand high-voltage high-precision
terminal, and 200CH measurements are available with the extension terminal base. In addition, when
connecting various modules, the voltage, temperature and humidity as well as the acceleration, AC current,
CO2, and illuminance / ultraviolet etc. can be measured.
The GL840 can save the high-capacity measurement data directly in the internal memory or SD memory
card.
For the PC interface, as USB and Ethernet is included as standard, system conguration according to use
is possible. As the Ethernet function is equipped with both WEB server and FTP server functions, remote
supervision and data transfer are also possible. In addition, when the wireless LAN and Petit LOGGER
GL100-WL are combined by installing the wireless unit, the multipurpose remote measurement is also
possible.
1.2 Features
Input
Adoption of a pluggable M3 screw type input terminal facilitates wiring.
•
20CH measurements are supported by the standard terminal or Withstand high-voltage high-precision
•
terminal, and 200CH measurements are supported by the extension terminal base.
When using the Graphtec’s GS series and terminal / adapter, the acceleration, AC current, CO2, and
•
illuminance / ultraviolet measurements are also possible.
Because that standard terminal and Withstand high-voltage high-precision terminal have a whole CH
•
isolated, the different standard signals can be measured at the same time. In addition, when using the
Withstand high-voltage high-precision terminal, the measure environmental conditions of high withstand
voltage can be applied.
Display & Operation
With the GL840’s high-resolution 7-inch TFT color liquid crystal display, you can conrm the waveforms of
•
measured data and each channel’s settings at a glance.
Easy operation is achieved through a straightforward menu structure and key allocation which resembles
•
mobile phones.
Data Capture
The high-capacity measurement data can be saved directly in the internal memory or SD memory card.
•
Because the SD memory card is used as an external memory, you can measure a long period of time with
•
peace of mind while data backup.
* 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 internal memory, 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 msec per channel by using fewer measuring channels. (Temperature measurement can be done at
sampling rates of 100 msec and higher.)

1.3 Operating Environment
This section explains the operating environment for the GL840.
Ambient Operating Conditions
(1) Ambient temperature and humidity (the GL840 must be operated within the following ranges.)
• Temperature range: 0 to 45°C (0 to 40°C when a battery pack is mounted, 15 to 35°C when battery is
being charged)
• Humidity range: 5 to 85%R.H.
(2) Environment (do not use in the following locations.)
• A Location such as being exposed to direct sunlight
• Locations exposed to salty air, corrosive gases, or organic solvents
• Dusty locations
• Locations subject to vibration or impact
• Locations subject to voltage surge or electromagnetic interference such as lightning or electric furnaces
(3) Installation category (over-voltage category)
• The GL840 belongs to Installation Category II dened in IEC60664-1.
• Never use the GL840 for Installation Category III or IV.
(4) Measurement category
• The standard terminals on the GL840 are not used for Measurement Category II, III, and IV.
• The Withstand high-voltage high-precision terminal for the GL840 belongs to Category II. However, it is
not available for Category III or IV.
•If condensation occurs...
Condensation occurs in the form of water droplets on the device surfaces and interior when the GL840
is moved from a cold to a warm location. Using the GL840 with condensation will cause malfunctioning.
Wait until the condensation has disappeared before turning on the power.
Warming-up Before Use
The GL840 should be allowed to warm up with the power turned on for approximately 30 minutes to ensure
that it operates according to the specied performance.

CHAPTER 1 General Description
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 GL840.
•
For stabilized temperature measurement, allow the GL840 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
GL840.
To conduct measurement in noisy environments, connect the GL840’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 GL840 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 GL840 is shipped overseas. To change the display language, see the instructions in "OT HER:Language".

The setting selected in this eld is displayed in "Arbitrary unit."
Arbitrary text consisting of alphabetical characters and numerical values can be set as a unit.
(For the character input, refer to “(9) Character string input” in “3.4 Setting Menus”.)
When “Select Unit” or “Unit” is specied, it is reected in here.
When "Select" or "Unit" is used, the setting is reected in this eld.
If a message window opens, follow the instruction in the message to change the setting value.
•
The Scaling function performs calculation using a ratio of the Meas. Value and EU Output Value settings.
•
The digital display shows “++++/----” when the converted value cannot be processed by the GL840.
•
The span may be varied depending on the scaling settings.

When setting the pulse input to the number of revolutions, set the number of pulses per
revolution.
As the number of pulses per revolution set here is 1 revolution, the number of revolutions per
minute (RPM) is calculated.calculated. For example, if “100” is set, 1 rotation is judged when
100 pulses have been input.
<Calculation formula>
Number of revolutions (RPM) = Pulse input frequency ÷ Number of pulses per revolution x
60 (1 minute)
