SETTING THE SENSOR MODULE AND MAIN UNIT

In the case of the temperature and humidity sensor (GS-TH), set the sensor module and the main unit in a way where the sensor faces the upper right corner of the main unit as shown in the figure. For other sensor modules, set so that the cable faces to the lower right portion as the connector fits into the main unit GL100 body.

 

WHAT IS THE POWER SUPPLY RECOMMENDATION FOR THE GL100?

The power supply is available using either USB bus power from PC, USB AC adapter or two AA alkaline batteries.

 USB AC adapter: Specifications, 5V 1A, USB bus power: 5V 200mA

 Battery drive is available only for AA alkaline batteries. Rechargeable batteries cannot be used due to insufficient voltage.

 CO2 sensor cannot be used with battery drive.


Recommended power supply combined with the specific sensor modules are:

Setting Connection module Alkaline dry battery USB power supply
Temperature / humidity setting GS-TH O
3 axis acceleration / temperature measurement GS-3AT O
4 ch voltage / temperature measurement GS--4 VT
4 ch Thermistor temperature measurement GS-4 TSR O
Illuminance / UV measurement GS-LXUV O
CO2 measurement GS-CO2 X
AC current / power measurement GS-DPA-AC O
Temperature / humidity + CO2 setting GS-DPA + GS-TH + GS-CO2 X
Temperature / humidity + illuminance / UV measurement GS-DPA-AC O
CO2 + illuminance / UV measurement GS-DPA + GS-CO2 + GS-LXUV X

◎: Available
O : Operable with alkaline AA dry batteries. (Wireless LAN usage is not recommended)
△ : Operable with alkaline AA dry batteries, however use time will be limited due to high current consumption. USB power supply is recommended.
X:  Not available. ※GS-DPA is the dual port adaptor for dual sensor packages.
※ Whenever wireless LAN is in use with the GL100-WL, current consumption increases and the operation time with dry cell batteries becomes extremely short. USB power supply is recommended when wireless LAN is in use.


HOW LONG WILL THE AA ALKALINE BATTERIES LAST WHILE MEASURING WITH A TEMPERATURE / HUMIDITY SENSOR?

Approximately 2 weeks.


※ With the following conditions.
■ Temperature / Humidity Sensor (GS-TH)
Sampling speed at 1 minute / Internal memory recording / No micro SD card / Screen saver ON / Wireless LAN OFF.

Battery operation time varies with parameters for usages and operating temperature. Available usage time may change depending on the type of module used. By turning the power off while it is not in use, battery life can be extended. New alkaline battery life is typically about 5 months (at 25 ° C).

● DC current consumption is as follows.
In cases when using external battery drives, you can reference the following consumption chart (mAh) based on the sensor you’ll use.

WHAT IS THE WATERPROOF AND DUSTPROOF MEASURE OF THE MAIN BODY?

The main body compact datalogger GL100 conforms to IP54 of the IEC standard, and it has a dustproof standard grade of 5 and waterproof standard grade of 4.


※ IP54 is for dust prevention that prevents the prescribed operation and safety of equipment and water splashing.

※ The spec is for operating on its own without any external power supply driven with AA alkaline battery and the connector cover is attached.


CAN I OUTPUT AN ALARM SIGNAL TO AN EXTERNAL LIGHT OR BUZZER?

An alarm signal can be put out from an isolated switching photo coupler on the GL100 main body using the alarm conditions set on the main GL100 options.


(Rating: 30 V, 50 mA (Power dissipation 150 mW))

With the wireless LAN-equipped model (GL100-WL), alarm information can also be sent by email to the specified email address.


HOW DO I CONNECT THE GL100 TO THE PC?

 

Both Wireless LAN model GL100-WL and non-wireless LAN model GL100-N can be connected to the PC using USB cable with Micro B-A type cable. Wireless LAN model GL100-WL can be connected to the PC with the wireless LAN, however only one PC and smart device is allowed to connect simultaneously over the wireless LAN.

Step1:  Make sure you have downloaded the USB driver and the APS software  >> CLICK TO DOWNLOAD

Step 2:  Plug in your GL100 via USB into the computer.  Open the GL100_240_840APS and hit the “Choose” option to get to the drop down menu. The easiest way to discover your device would be to “Search”.  Once the IP address is found, hit connect. When the icon turns green, connection is established. You can hit the Close button at the bottom right hand corner to start the monitoring via wireless connection.


HOW CAN I RETRIEVE THE DATA?

 

Both the wireless LAN equipped, GL100-WL, and the one without wireless LAN, GL100-N, can connect to a PC by USB and files can be downloaded using the dedicated software or by transferring the data on the Micro SD card.   Wireless LAN equipped models can connect to a PC via WLAN and the data can be retrieved with the APS software.

Step 1: When connected, hit the MENU for the drop-down option and select the open file option.

GL100 - Retrieve the data.png

Step 2: From the new window, choose your file you wish to view and highlight the selection by clicking on it. Press select file on the bottom of the open file window. Your file will now open up in the software for playback and review.


WHAT ARE THE WIRELESS LAN STANDARDS AND COMMUNICATION DISTANCE OF THE GL100-WL?

Wireless LAN used on the GL100-WL is IEEE802.11b with 2.4 GHz band radio waves.
In an open environment without any obstacles, the communication distance is approximately 40 meters.
※Result depends on the site.  Real time transfer rate: max ½ sec.


WHAT WIRELESS LAN MODES AND SECURITY SETTINGS CAN BE SET WITH THE GL100-WL?

The wireless LAN mode that can be set with GL100-WL can be set to Off, access point (GL100-WL acts as a hot spot), and station (GL100-WL will be set as a terminal on a network).
For security settings on the GL100-WL, you can set the GL100-WL to Auto (WPA / WPA 2 is automatically recognized), WEP, WPA, and WPA 2.


WHAT INFORMATION CAN I SEND WITH THE GL100-WL?

 

Email notices can be sent on alarm trigger, low battery status, signal strength low (RSSI), and disk full notice along with the real time data on the wireless notification.


WHAT IS THE RECOMMENDED SD CARD?

 

Our recommendation is Micro SDHC card that supports sleep mode.  The format does have to SDHC.
Sample recommendation: TS4GUSDHC4 (Transcend)


Is it possible to measure both temperature and humidity at the same time?

The temperature and humidity sensor (GS-TH) connected to the main GL100 will both measure and record both temp and humidity.  


Is it possible to measure room temperature at multiple places with certain accuracy?

Yes, it is. 

By connecting the 4-ch thermistor terminal (GS-4 TSR) with the optional thermistor sensors, it is possible to measure at 0°C to 35°C with accuracy of ±0.2°C. The thermistor accuracy is ± 0.4 ° C (typical value).
