Pressing the "Reprogram" button on the Details Tab will display the Settings Tab.

 

SettingsTab

 

This screen is used to configure the temperature logger for sampling.

 

The main sections that need configuring are as follows.

 

Description

 

clip0015

 

The description is saved with the logger. It is displayed at the top of the log screen, on reports, and is part of the file name when saved to file.

 

The description can be any thing you like but we recommend that you include the name of fridge/freezer if possible, and also the name of your company.

 

The description normally should not include the date because the date will be included in the saved file's properties anyway.

 

Sample rate

The sample rate determines how often the reading will be made.

 

As a general rule of thumb, a sample rate of between 5 minutes and 30 minutes is typical for most users.

 

For more information see the following section on Sample rate

 

Rollover

The allow rollover flag is used to determine what the logger will do once the memory is full.

 

By default it is turned on and should generally be left on. This ensures that the logger will always have the most recent readings in memory.

Start Delay

 

clip0018

 

The start delay is how long the temperature logger will wait until it starts recording the temperature. This feature makes it possible to pre-program the temperature logger without impacting on the results.

 

For example, the temperature logger could be setup in the office and then taken to site during the day. In this case a 12 hour delay would provide sufficient time for the temperature logger to be installed. After 12 hours they would then start sampling.

 

It is possible to set the sample rate either by a fixed offset (in minutes) or at a specific date and time.

 

On some units it is also possible to have logging start once the minimum or maximum alarm temperature is reached.

 

Most users will typically use "no delay", or may use the "specify delay date and time".

 

Alarm limits

 

AlarmLimits

 

The alarm limits have a minor role. When the results are retrieved and displayed in the log, they will be colour coded depending upon if they are too high (red), too low (blue) or in range (green).

 

The default values for high and low and the alarm limits. Note the emphasis on default because the user can manually change them later.

 

Start Button

 

StartStopButtons

 

The start button will download the current settings and then start the unit logging.

 

If the unit is already logging then the start button won't be enabled but the stop logging will be. In this case press the stop logging first and then the start logging.

 

Note: If you stop the unit logging you will still be able to retrieve the logged results in it. Once you restart it, the results will be cleared. You must download the results before pressing start.
