Note:        When using the instrument with WiFi™ connectivity, do not use any of the controls in the Recording field. The instrument will be completely controlled by the server, including starting the recording, erasing memory if required, and resetting the time.

The recording field has three buttons:

•Record                The Record button is used to immediately create a new record and start recording. The new record is placed in memory immediately after the last one. The recording stops when the memory is full, or when the Record button is pressed again. The recording parameters, such as number and types of values recorded…etc. must be adjusted prior to starting the recording.
•AutoRec        The Auto-Rec button is used to place the instrument in or out of the Auto-Rec mode. In the Auto-Rec mode the instrument stays semi-dormant, sampling the acceleration or velocity in the background, as long as it does not detect an acceleration or velocity value beyond an adjustable threshold. When the signal value goes over the threshold, the instrument wakes up and starts recording, using the recording parameters in effect in the instrument’s configuration. When the signal value goes and stays below the threshold for a set length of time, the recording stops and the instrument goes back to sleep.
When the Auto-Rec mode is selected, the instrument will first wait for the signal to rise above the set threshold before starting the first recording. The next period of inactivity will stop the recording, and so on until the user exits the Auto-Rec mode, or the memory is exhausted. A new record is created every time the threshold is passed and the instrument is not already recording.

Note:        The threshold is expressed in m/s2 for acceleration and in m/s for velocity.

 

Note:        The threshold T can only be positive. When recording raw signals or signal statistics the recording is triggered as soon as the signal goes higher than +T, or lower than -T. When recording RMS levels, the recording is started as soon as the RMS level goes higher than +T RMS.

•Timer                The Timer button is used to set a time and date to start the recording automatically. This is only allowed when a recording is not already in progress. To set the timer, press the Timer button. Then set the recording date and time, and press the OK button to arm the timer. The timer will start an immediate recording, or start the AutoRec mode, depending on the settings.
•Erase                The Erase button erases unconditionally all the data that has been recorded in the instrument, making room for new records.

The Memory Depth bar provides two indications:

•The percentage of memory already used (indicated by the green bar). The bar is completely grey when the memory is empty and completely green when the memory is full.
•The total memory time, in Days-Hours-Minutes-Seconds. The total memory time is displayed at the right extremity of the scale. It is calculated as a function of the instrument settings, such as log interval, statistics recorded…etc. Therefore it will change dynamically as the settings are modified, to reflect the new overall memory time.
