XI. TEMPERATURE CALIBRATION
The temperature calibration built into the units is traceable to NIST. It is stable and will
hold without drifting. However, our standards for temperature measurement may not
be the same as the users. Therefore, these units are designed to be calibrated in the
field by the user. Follow the easy instructions below if calibration is wanted or needed.
Note: The calibration is two-point for optimum accuracy. Therefore, if calibration
is changed, it is best to first clear the old calibration in memory. The unit is
calibrated at the factory at 5

C and 70

C.
To calibrate the units follow the instructions below. NOTE: THE PLATE SURFACE
AND BLOCK SURFACE MEASUREMENTS ARE DIFFICULT TEMPERATURE
MEASUREMENT TO MAKE ACCURATELY. Check with the factory if help is needed.
Also, calibration kits are available. The IC50-700 is the probe calibration kit, and the
plate and probe calibration kit is IC50-800. The IC50-800 includes the probe calibration
kit and a temperature meter and surface temperature probe like the ones we use here
to calibrate the units in the factory. The probe circuit is calibrated using precision
platinum resistors that equate to the temperature values of 5.0°C and 70.0°C. These
resistors are mounted into packages that plug into the rear of the unit in place of the
probe. Follow the instructions below to calibrate the plate surface, block surface or
probe.
