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” has 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 datalogger reports are Y2K complaint using an industry standard
algorithm to form a 4 digit year field.
To perform a 32ºF (0ºC) RTD calibration:
Immerse RTD sensor in deionized water and ice mixture. Stir the mixture constantly.
Move the highlight to [RTD1] by pressing .
To access the [RTD] option list press .
Move the highlight to [User Cal] then press .
This triggers the prompt:
ENT
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.
Ice Bath RTD Calibration
Use distilled, deionized water and ice mixture at 32ºF (0ºC) equilibrium for an ice bath. Ensure tempera-
ture with a reference thermometer. Siemens can not assume responsibility for the incorrect design,
construction or operation of an Ice Bath.
CAUTION: DO NOT ALLOW AN RTD SENSOR TO MAKE DIRECT CONTACT WITH ICE
DURING AN ICE BATH CALIBRATION.
When you are sure that the RTD sensor is at 32ºF (0ºC), press to recalibrate the RTD sensor. To
verify the calibrated reading, go to the [Diagnostics/Liquid Data] menu cell to check the current RTD out-
put. Make sure that it coincides with the reading of the reference thermometer.
5.10.8 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.
