TRIPLETT RHDL50 Humidity and Temperature Data Logger User Manual

TRIPLETT RHDL50 Humidity and Temperature Data Logger

Introduction

Congratulations on your purchase of the Triplett RHDL50 Relative Humidity and Temperature Datalogger with LCD Display. This data logger measures and stores up to 16,000 relative humidity and 16,000 temperature readings over 0 to 100%RH and -40 to +70°C (-40 to +158°F) measurement ranges. The user can easily configure the logging rate, high/low alarm, and start mode, and download the stored data by plugging the module into a PC’s USB port and running the supplied PC software. Relative Humidity, Temperature and Dew Point data can then be graphed, printed and exported to other applications. The data logger is supplied with a long-life lithium battery, which can typically allow logging for one year. This meter is shipped fully tested and calibrated and, with proper use, will provide years of reliable service. Please visit our website (www.triplett.com) to check for the latest version of this User Guide, Product Updates, and Customer Support.

LED Status Indication

• To save power, the RHDL50’s LED flashing cycle can be changed to 20s or 30s via the supplied software.
• To save power, alarm LEDs for temperature can be disabled via the supplied software.
• When the battery is low, all operations will be disabled automatically. NOTE: Logging automatically stops when the battery weakens (logged data will be retained). The supplied software is required to restart logging and to download logged data.
• When both temperature and relative humidity readings exceed alarm level simultaneously, LED status indication alternates every other cycle.

Operation

System Software Required:

Windows 7, Windows 8.1 or Windows 10

Minimum Hardware Required:

PC or Notebook with Pentium 90MHz or higher 32 MB RAM; B At least 7 MB of hard disk space available to install Datalogger USB software. Recommended display resolution 1024X768 with High Color(16 bit).

INSTALLING THE GRAPHING SOFTWARE and USB driver
Install the supplied Windows PC Datalogger Software by placing the supplied program disk in the PC’s CD-ROM drive or by downloading the program from the http://Extech.com/instruments/software.aspwebpage.
If the installation program does not automatically open and provide on-screen prompts, open and browse the CD-ROM drive, then find and double-click on the SETUP.EXE file included on the program disk. Follow the on-screen prompts to complete the installation.

Software Install

Run SETUP.up.exe and follow the defaults to install the RHDL50 software

USB Driver Install

1. Open the root folder of the RHDL50.
2. Open the folder Driver\DriverUSBXPRESS and double-click on USBXpressInstaller.exe.
3. Follow the default choices to load this USBXpress driver.

Note: When the RHDL50 is connected to the USB port, the battery inside the device is discharged at a higher rate than normal. To conserve battery life, do not leave the RHDL50 connected to the USB port for a prolonged period of time

RUNNING THE GRAPHING SOFTWARE
With the RHDL50 inserted in the PC’s USB port, double-click the Datalogger Graph icon on your desktop to launch the program. The opening screen will appear as shown below.

The logger will automatically connect and connection status is shown at the lower left hand corner of the screen. Click on “Help” and “About” to view the version number,

MENU BAR DESCRIPTION

The main menu for the software appears as follows:

LOGGER SETUP

• The CURRENT TIME field will automatically synchronize with the PC date and time setting.
• The MANUAL and INSTANT select buttons allow the user to start data logging immediately when the Setup window is exited (INSTANT), or at a later time (MANUAL).
• The LOGGER NAME field allows the user to select a unique name for the RHDL50.
• The SAMPLE POINTS field instructs the RHDL50 to take a fixed number of readings.
• The SAMPLE RATE pull-down menu instructs the RHDL50 to log readings at a specific rate.
• The LED Flash Cycle can be set by the user: longer cycle times help to extend the battery life.
• The ALARM SETTINGS area of the SETUP window allows the user to set high and low temperature and humidity limits and to disable the flashing of the RHDL50’s LEDs, thereby conserving battery energy.

Once the changes have been made, click on the SETUP button to save them. Press the DEFAULT button to set the RHDL50 back to factory default conditions. Press the CANCEL button to abort the setup.

Note:

Any stored data will be permanently erased when the user clicks on Setup. To save the data before creating a new
setup, click Cancel and then download the data. The battery may run out before the RHDL50 has finished collecting a specified number of sample points. Always ensure that the remaining charge in the battery is sufficient to last the complete duration of your logging exercise. When in doubt, we recommend that you always install a fresh battery before logging critical data. If INSTANT was selected in the SETUP window, the RHDL50 begins logging at the instant the SETUP button is pressed. If MANUAL was selected, the RHDL50 must be manually started by pressing and holding the device’s yellow button for approx. 3 seconds, or until the two LEDs on the RHDL50 flash at the same time. Logging will continue at the programmed sample rate until the number of readings (sample points) specified in the Setup window is reached. The green LED flashes once per sample point and the red or yellow LED flashes when user- programmed alarm limits are exceeded. For details, see the LED status guide.

Battery Replacement

It is highly recommended that the battery be replaced every 12 months, or prior to logging critical data. The RHDL50 does not lose its stored readings when the battery weakens or when the battery is replaced; the data logging process will however be stopped and cannot be re-started until the battery has been replaced and the logged data has been downloaded to PC. Use only 3.6V lithium batteries. Before replacing the battery, remove the datalogger from the PC. Follow diagrammatic steps 1 through 4 below.
NOTE: Leaving the RHDL50 plugged into the PC USB port longer than necessary will cause some of the battery capacity to be lost.

WARNING: Handle lithium batteries carefully, observe warnings on battery casing. Dispose of in accordance with local regulations. Safety: Please dispose of batteries responsibly; never dispose of batteries in a fire, batteries may explode or leak. If the meter is not to be used for 60 days or more, remove the battery and store it separately.
