35 V. DATALOGGING Notes on Datalogging: This instrument provides 2 modes for Datalogging: Immediate and scheduled; but only 1 actual recording period is available at any time. When immediate datalogging is selected, any previously scheduled datalogging is cancelled and times set for a scheduled logging event will be lost. When datalogging is either in progress or scheduled, observation of the LED will indicate the current status of the instrument. When datalogging has been scheduled, but has not yet started, the LED will blink approximately every second, with equal brightness flashes until the logging starts. If the instrument has entered datalogging mode, the LED will blink approximately every second but with variable brightness flashes, in the sequence of: dim -normal-normal-normal-bright. In either mode, the LCD screen will remain blank until datalogging has finished, after which it will display the screen appropriate to the selected function. With the exception of Transient Detection data, the instrument must be connected to a Personal Computer to view the logged information Logged data may be downloaded to, viewed and saved on a Personal Computer running the Download and Datalogging software via the USB link. The data stored in the instrument can then be erased. To erase the stored data, turn the instrument off, hold the REC button down whilst turning the instrument on, then press the HOLD button down for 2 seconds until 2 beeps are heard.
