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 in tenths of seconds up to 1 hour.

13.1 Clock

The clock is used:
1.
2.
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 status. 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 start or stop at a given time
you can instruct one channel (or all of them) to do so.
Example 1: To turn off channel #2 at 3:45 (as counted by the clock) -
Press keys: 'TIMER, ENTER'.
Now the timer shows its last setting (if no instruction was inserted, it shows 'OFF').
Press key: 'OFF, 2, ENTER, 3, ENTER, 45, ENTER'.
Check by pressing: 'TIMER, ENTER'.
To exit from the TIMER checking - Press key: 'CLEAR-DISPLAY'.
Example 2: If the TIMER is already set and you want to cancel the TIMER action, you
can turn the TIMER off.
Press keys: 'TIMER, OFF, ENTER'.
