DICKSON HT300 Bottle Logger User Guide

Each end of the HT300 can be removed. The battery is located on the cap end with the lanyard hole. Note the battery symbol etched on this end of the case.
Remove the cap carefully by twisting the cap counter clockwise.

Insert the battery positive side in first.
Replace the battery cap tightly.
It may take up to 5 seconds for the unit to power on.
Open DicksonWare™ software via the icon on your desktop.

NOTE: It is very important to attach the correct cap to the correct end of the case. The cap end with the lanyard hole and spring must always go on the battery end of the case.

Setup Logger

The USB port is located opposite end of the case. Note the USB symbol etched on the USB access end of the case.
Remove the cap.
The USB port is just inside the logger opening.
Connect the USB cable to the logger and to an available working USB port on your PC.

Your computer should detect the logger when it is powered on and connected to the computer via the USB connection. Depending on your version of Windows, the computer may go through an Add New Hardware routine. Click on the Setup button. You will be prompted to select USB or Serial COM Port Connection. Select USB then Click Continue. A Setup window will appear. All fields should be automatically filled in, confirming that DicksonWare™ has recognized your logger. Should all fields remain blank, refer to the troubleshooting section in this manual
Once DicksonWare™ recognizes the logger, press the Clear button. This will delete all data currently stored.

The logger is now ready to be placed in the desired logger location.

Software

(All of these features can be modified by click on the main Setup button.)
Setup (button)
Click this button first to establish communications between the logger and
DicksonWare™ software. You may be prompted to select the communication method between USB or Serial COM port. You may save this setting so you will not be prompted again. This setting is also changeable in File/Preferences/Communications. A Setup window will appear with “all fields” populated. This confirms that the software has recognized the logger. Should the fields remain blank then communication has not been established, refer to the Troubleshooting section of this manual

Identification (tab)
This tab provides you with the model and serial number of the logger, as well as the option to set a custom “User ID” by clicking the active “Setup” button to the right of the “User ID” field. This tab also includes the date the unit was calibrated, calibration interval, and factory calibration date.
Samples (tab)
The majority of the setup process takes place in this section. Each field with an active “Setup” button to the right, is a parameter that you can customize.
Sample Interval: Tells your logger how frequently to take and store readings.
This can be done in 1 or 10 second intervals. The dialog box for editing the sample interval also indicates how long it will take for the logger memory to fill up with new readings before it either stops saving new samples or begins to wrap. “Sub ten second interval” should be enabled for desired sample intervals under 10 seconds.
Stop or Wrap when Full: Determines what the logger should do when it is full. The logger will either stop and discontinue logging, or continue logging by wrapping the newest data over the oldest data.
Note: When changing logger settings (sample interval, stop/wrap, and start date and time) the logger will automatically clear all stored data.
Channels (tab)
Click the Adjust button to the right of the temperature value for channel 1 to change the name of the channel.
Alarms (tab)
Alarms are not active on this model.
Download (button)
From the main menu, click on the Download button to automatically extract all logged data into a graph and table format.

Customized Graphed Data

DicksonWare™ calculates MIN, MAX and AVE of all data collected. Customize data by eliminating unnecessary data points and customize MIN, MAX and AVE to show only desired information.

Export Data

A snapshot of your graph or a real-time graph of points can be easily exported to other programs such as Excel or PowerPoint.

Calibration

A Zero Adjust calibration can be performed on this logger. SW400 calibration software is required. Note: It is strongly recommended that a higher accuracy NIST’d instrument should be used as the standard.
For more accurate calibration, return the instrument to Dickson for calibration in our A2LA Certified Jab. Contact Customer Service for a Return Authorization Number before returning for calibration.

Need to Know

Logger Settings: When changing logger settings (sample interval, stop/wrap and start date and time) the logger will automatically clear all stored data.
Fahrenheit/Celsius: The DicksonWare™ default is Fahrenheit. To change graph view in DicksonWare™ to Celsius, go to File/Preferences to change unit of measure.
IP Rating:
The logger has an IP rating of 68 in up to 50 meters of water.
Downloading: Do not open the logger (remove caps) until the logger has returned to ambient temperature.
Power:
Battery Type: Tadiran TLH-5955 high-energy lithium battery, Quantity 1, Dickson part R170
If the battery is low: Removing the battery will cause the logger to take a dummy reading of -414F to mark the point where power was restored. Replace the battery and clear the logger in DicksonWare™ before using.
Note: Power draw from the battery cannot be turned off. If decommissioning a logger, remove the battery. To achieve longer battery life during operation, use a less frequent sample rate and disconnect the unit from the USB when not downloading.

Troubleshooting

Can the HT300 be used in an autoclave or incubator?
Yes it is perfect for both applications.
Why won’t the logger communicate?

Is the correct version of DicksonWare™ (v17.23 being used)? If not contact customer service for the latest version.
Make sure the battery is good.
Confirm that USB is selected under File/Preferences/Communications
Try another available USB port. If this is the first time attempting to communicate on this PC, or if new software or programs have been installed since the data logger was last used, try reinstalling the software or installing the software on a different PC.

Why does my downloaded data show a -414 reading?

You will see a -414F reading if the battery was removed at any time. This marks the point at which logging was resumed once the battery was replaced.

Will I lose any saved logged data when replacing the battery?
