4.12.7 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 pro-
vides the Datalogger and Stripchart date and time stamps.
Notice:
All Siemens 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” will have no effect
on the proper functioning of any of our systems. Regarding the arrival of the year 2000, since
our real-time clock uses a six-digit code for month/day/year [MM.DD.YY], the first day of the year
2000 will be: [01.01.00].
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, 2001 by typing 12.07.01.
To enable numeric entry press <Right Arrow>, then type in the reading of the reference ther-
mometer (e.g., 72.0).
To recalibrate the RDT sensor press <ENT>. To verify the calibrated reading, go to [Diagnostics/
Liquid Data] to check the current RTD output. Make sure that it coincides with the reading of the
reference thermometer. Repeat for the other RTD if necessary.
Calib @ deg F
=72.0
NOTE: Factory Calibration provides an additional prompt after a new temperature is entered:
[Are you Sure? No Yes]. It is recommended that you use [User Cal] to avoid alteration
of preset factory calibration.
RTD Calibration By Data Entry
The RTD Calibrate menu allows you to adjust the intrinsic RTD reading to match an external reference
thermometer by directly entering its reading. Only perform this procedure while the RTD under test is
installed and currently measuring temperature.
To enter the current RTD temperature
Move the highlight to the RTD you want to calibrate (RTD1 or RTD2).
To access the RTD option list press the <Right Arrow>.
Move the highlight to [User Cal] or [Factory] Cal then press <ENT>. This triggers the pop-up
window:
Calib @ deg F
=32.0
