The purpose of this article is to review how to use the Logging function.
To begin with the internal memory capacity is 65,000 Data point sets and each set includes the Minimum, Maximum and Average reading over the interval time you set. The sampling rate of the meter when gathering data is 125ms or we can say 8 readings per second. To give an example if we set the Interval time at 1 minute the meter will gather the 8 readings per second for 1 minute (480 readings) and keep the highest reading, lowest reading and the average. Keep in mind the battery life of these instruments is 150 hours and that is the maximum length of time for recording. In the example of setting the interval to 1 minute and record for 150 hours you would only use 9,000 data points sets of the maximum 65,000.
The process for managing the Interval Logging time, Duration of the Logging session and deleting the memory will require you use the Fluke Connect App on your phone. A new meter does not have a reference to the correct date or time so you need to sync the meter to your phone using the Fluke Connect App to set the correct date and time before Logging or your time and date will be incorrect.
Also need to sync to your phone using the Fluke Connect App after replacing batteries in the meter because it will not hold the previous sync time and date when batteries die.
Below is a picture of the Fluke Connect App once you have connected to a Fluke instrument, in the example the Fluke-378FC is shown. Below the picture are some instructions on how to manage the Logging function.
The picture below are the choices to manage the Logging function after you tap on the three black dots in picture above. You can manage the Logging Interval, Duration, Start or Stop, Downloading and Clearing the internal memory of the Fluke meter. When you tap on the Interval or Duration the picture to the right is the menu for adjusting the Internal, Duration for Manual Stop or Automatic Stop. The Automatic stop allows you to set the length of time and it will stop after that duration.
The Fluke Connect App also has a Record feature and the maximum length of time is 10 minutes and the interval is fixed at 1 second. After 10 minutes the recording will stop or you can tap on the red square icon at the bottom of the App screen to stop it before 10 minutes.
After you stop the recording the screen will change and show you the recording trend and the ability to put notes in the recording as well as sending the information to someone via Email or Text.
