Page 6: Operation
Operation NOTES: 1. Adobe Reader® software is required. 2. Ensure the logger is at room temperature before inserting it into a PC port. 3. The executable file for programming is named “PDF Logger Configuration Tool”. 4. A datalogging session cannot start until the datalogger is properly configured. Configuring the TH30 and RHT30 for a Datalogging session At any time before logging is started, the logger can be programmed and re‐ programmed. The previous logging session will be deleted once a new session is started. 1. Connect the data logger to a PC via the USB port. The logger will switch ON automatically. Note that a short press of the power button will also power the logger. 2. The LED will glow green while a connection with computer is being established. 3. An AutoPlay prompt will appear on the PC when communication is established. 4. Click on ‘Open folder to view files’ to see the available files. Open the program "PDF Logger Configuration Tool.exe". 5. The default language is English; select German, French, Italian, Spanish, or Portuguese as desired. The generated logging report format will match the language selected. 6. To review the User Manual, click ‘Manual’ to open the User Manual PDF file. 7. The parameters needed to configure the datalogger for logging are defined below. Refer to the earlier screen shot of the ‘PDF Logger Configuration Tool’ window for reference: Datalog Sampling Rate Select the datalogging sampling rate (recording interval) from 30 seconds ~ 120 minutes. The default setting is 30 seconds. ... - Page 7 Alarm Delay The preset alarm delay time for the Single Event Alarm mode is always zero. The adjustable delay time range for the Cumulative Alarm is 5 ~ 120 minutes. Alarm Modes Single Event Alarm mode: The LED immediately starts flashing red every 10 seconds when the measured value exceeds the alarm threshold. Cumulative Alarm mode: The LED begins flashing red only after the average value exceeds the alarm threshold and also after any programmed Alarm Delay time. See Alarm Delay parameter above. Alarm Disable (default): Alarm function disabled. Alarm Note: The LED will continue flashing red every 10 seconds (once it is triggered by an alarm) even when the measurement later returns to the normal range. To stop the LED alarm, plug the logger into the PC USB port to generate a report, or power off the logger (short press of the power button while it is not connected to the PC). Alarm Limits Select the alarm threshold ranges for air and external probe temperature (TH30) or air temperature and RH% (RHT30). For example, if the external o probe temperature range is set to 2.0~8.0 C, when the measurement falls o below 2 C or exceeds 8 C the LED will flash red every 10 seconds. Note: If an alarm occurs between two logging points, the logged data will not show the alarm but the LED may still flash red every 10 seconds, especially in Single Event alarm mode. If desired, use the Cumulative Alarm mode to minimize this effect. Password A 16 alphanumeric character (max.) password may be used to prevent unauthorized re‐programming. User Company Name Input a company name to be included on the log report (20 characters max.). A Note On Time Zones ...

Page 8: Start Datalogging
Start Datalogging 1. Configure the logger as previously described and then hold the Start/Stop button for 5 seconds to start logging. 2. Measurements update on the display every 10 seconds. For the RHT30 the temperature and RH% displays toggle every 5 seconds. 3. If the logger is programmed with a Start Delay: After pressing and holding the Start/Stop button for 5 seconds to start logging, REC will appear on the LCD but will not flash until the delay time has elapsed and logging has begun. 4. When the datalogger is successfully running, the LED flashes green every 10 seconds (as long as there is no alarm). Monitoring Alarms While Datalogging The LED will flash RED every 10 seconds when there is an alarm. The display also shows ‘L’ for low alarm and ‘H’ for high alarm. To stop the LED from flashing red, plug the logger into a PC, or power off (short press of the power button). Placing ‘Bookmarks’ While Datalogging To place a bookmark manually during datalogging, press and hold the MARK button until the measured reading flashes 3 times. Up to eight (8) bookmarks can be placed; the bookmarks will appear in the logging report. MAX‐MIN Readings Short press the MAX‐MIN button to step through the highest (MX) and lowest (MN) readings stored in memory. Checking Battery Status At any time, short press the MARK button to view the approximate number of days remaining for battery life. If battery power is critically low, the battery icon will blink once per second on the LCD display. Downloading Logged Data (PDF and Spreadsheet Datalog Reports) 1. Press and hold the Start/Stop button for 5 seconds to stop the datalogger. 2. Plug the logger into the PC USB port (this also stops the datalogger). 3. Open the ‘PDF logger Configuration tool’ from the list of available files. 4. Choose ‘Convert to PDF’ or ‘Convert to Excel’ to generate a report. ... -
