The SC310 has enough capacity for up to 1000 final results.
9.5.2 Making a recording
A recording consists of making a measurement and storing a series of functions with a
certain periodicity in the memory. These functions and periodicity are specified, for each
mode, in the recording setting. The main difference between the different kinds of recording
lies in the 'number of functions / storing time' compromise. See section 9.5.4.
Before beginning a recording, make sure there is no measurement in progress ( ).
To begin a recording, press . The screen will display the kind of recording together with
the register number. Next the functions selected for the type of recording will be saved
periodically in the memory until you stop the recording by pressing
.
During the
recording process, the measurement in progress icon ( ) will flicker.
9.5.3 Time synchronisation
The SC310 allows you to begin recording at the o’clock (hh:00:00). To access this option,
select SETTING
Î RECORDING Î TIME SYNCHRONISATION from the SC310 menu.
Once the setting has been made, all recordings will begin at the o’clock. In other words, once
recording has been started, the SC310 screen will display the message TIME
SYNCHRONISATION and will wait until the built-in clock reaches the o’clock time to begin
displaying and saving data.
