6.10.7 THE CLOCK SET MENU
The [Clock Set] menu cell 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 flowmeter
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, the 1020 datalogger reports are Y2K complaint using an
industry standard algorithm to form a 4 digit year field.
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 (.) sepa-
rator 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
<Up/Down Arrow> to remove the current setting.
To set the Date:
To enable numeric entry press the <Right Arrow>.
Use PC numeric keys or KeyPad to enter the date (MM.DD.YY).
To store the date press <ENTER>. This moves the cursor to [Time].
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
