THE CLOCK SET MENU
The Clock Set menu allows you to set the time and date. The meter uses its internal clock/
calendar to record the real-time when certain data and diagnostic events occur. In addition,
the clock/calendar provides the Datalogger and Stripchart date and time stamps.
Notice:
All Controlotron flowmeters include a real-time clock to provide a convenient date/time stamp for display
screens and datalogger reports. The operating system does not rely on the date and time-of-day for any flowme-
ter operation. Therefore, the “Turn Of The Century” had no effect on the proper functioning of any of our
systems. Although we limit the year to 2 digits in all our displays, 1010’s datalogger reports are Y2K complaint
using an industry standard algorithm to form a 4 digit year field.
4.7.1 DATE
The Date command sets the month, day and year for the meter’s internal clock/calendar.
Enter the date using the [MM.DD.YY] format. Replace MM with two digits to indicate the
month. Replace DD with two digits to indicate the day. Replace YY with two digits to indicate
the year. Type the period (.) separator between each set of digits. For example, you would
enter December 7, 1997 by typing 12.07.97. You can use the <Right Arrow> to move the cursor
back to a number if you need to re-type it. Press the <CLR> key to remove the current setting.
To set the Date:
To enable numeric entry press
Use the numeric keys to type the date (MM.DD.YY).
To store the date press . This moves the cursor to [Time].
4.7.2 TIME
The Time command sets the hours and minutes for the meter’s internal clock/calendar. Enter
the time using the [HH.MM.SS] format. Replace HH with 2 digits to indicate the hour (use 24-
hr. clock format). Replace MM with 2 digits to indicate the minutes. Replace SS to indicate the
seconds. You also have to type the period (.) separator between each set of digits. For ex-
ample, you would enter ten minutes after two o’clock in the afternoon by typing: 14.10.00 You
can use the <Right Arrow> to move the cursor back to a number if you need to re-type it. Press
the <CLR> key to remove the current setting.
