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.

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.

•

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?
