To perform a 32ºF (0ºC) RTD calibration:
Immerse RTD sensor in deionized water and ice mixture. Stir the mixture constantly.
Press to move the highlight to [RTD].
To access the [RTD] option list press to move the highlight to [User Cal] then press
. This triggers the pop-up window.
When you are sure that the RTD Sensor is at 32ºF (0ºC), press to calibrate the RTD
sensor. 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.

To recalibrate the RTD sensor press . To verify the calibrated reading, go to [Diag-
nostics Liquid Data] to check the current RTD output. Make sure it coincides with the
reading of the reference thermometer.

4.6.2 ICE BATH RTD CALIBRATION
Use distilled, deionized water and ice mixture at 0ºC (32ºF) equilibrium for an ice bath.
Ensure temperature with a reference thermometer. Controlotron can not assume respon-
sibility for the incorrect design, construction or operation of an Ice Bath.
CAUTION: DO NOT ALLOW AN RTD SENSOR TO MAKE DIRECT CON-
TACT WITH ICE DURING AN ICE BATH CALIBRATION.
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.
4.7 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 provides the Datalogger date and time stamps.

Notice:
All Controlotron meters 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 meter opera-
tion. 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, 1010 datalogger reports are Y2K complaint using an
industry standard algorithm to form a 4 digit year field.
