Instruction manual

13. Clock Options
In addition to its standard 8 channels, Master-8 features 2 internal clocks. The first is called ‘clock’ and
counts the time in seconds up to 24 hours. The other called ‘stop-watch’ counts the time by tenths of
seconds up to 1 hour.
13.1 Clock
The clock is used:
1. to measure the time that elapsed from an event (e.g. beginning of the experiments).
2. for the ‘TIMER’ option (see below).
The clock time can always be displayed by pressing the ‘CLOCK DISPLAY’ key. The clock can be
reset by pressing the ‘CLOCK-RESET’ key. The resetting can be performed only when the clock time
is displayed.
The clock never stops running. A second keystroke on ‘CLOCK-DISPLAY’ (or any other key except
the ‘CLOCK-RESET’ key) clears the clock display.
13.2 Stop-Watch
The first keystroke on the ‘STOP-WATCH’ key displays its present situation. Then every odd keystroke
activates it and every even keystroke stops it.
The stop-watch can be reset by the ‘CLOCK-RESET’ key only when the stop-watch time is
displayed.
Note:
The main ‘RESET’ key resets both clocks, regardless of what was shown on the display.
13.3 Timer
The TIMER is linked to the clock and can change the mode of any single channel at a fixed time. For
example, if you want to set the experiment to stop at a given time you can instruct one channel (or all
of them) to do so.
