A-2 FOT Lab Kit User’s Manual
The FOT Lab Kit provides a set of calibration-correction factors for
each input channel physically installed in the device. These factors
are set to a nominal value at the factory before shipment to the
customer. The items listed above, however may affect the
calibration of a device within its specific working environment.
For this reason the user must adjust these calibration factors as
needed during the installation procedure to ensure accurate
temperature measurements. The calibration procedure is semi-
automatic and should be straightforward and nearly foolproof if the
instructions are followed carefully. Please refer also to the
descriptions of the CTRL+K (Kalibrate) CC (Calibration Correction)
and CT (Calibration Temperature) commands in Chapter 4, “User
Interface Commands’’.
Calibration of the device should be verified on a regular schedule.
If you are unable to successfully calibrate the device please contact
LUXTRON Technical Support.
Automatic
Calibration
Correction
Automatic calibration correction for each channel is invoked using
the CTRL+K command. When invoked this functionality captures
several seconds' of data samples and compares the average of these
samples to the calibration reference temperature (please refer to the
description of the CT command, page 4-11 ).
Calibration Options
1. Self-Calibration – If the user has a stable temperature bath (i.e.
ice water for 0
o
C), they can calibrate the instrument
themselves using the instructions below.
NOTE For best performance the user should calibrate with a stable
temperature bath at the midpoint of the measurement range. For
example, if the user’s temperature range is 100
o
C to 150
o
C, the ideal
calibration point would require a stable temperature bath at 125
o
C to
calibrate the FOT instrument to achieve the best accuracy possible.
