— °U Cal, User Defined Temperature Scale . . . . . . . . . . . . . . . . . . . . .
°U allows resetting the calibration of the display by means of the formula:
°U = K1 (°C + K2) + K3
(To change readout to
°U
refer to )
At times there are slight differences between the displayed temperature and actual
temperature as determined by a certified temperature measuring device. Or, you may
wish to make the display match a particular value so you have standardization between
different laboratory instruments.
The default values for the K factors are:
Degrees
K1
K2
K3
Kelvin
1.0
0.0
273.0
Fahrenheit
1.8
0.0
32.0
Celsius
1.0
0.0
0.0
Use the K1 and K3 factors if you are using any of the three scales shown in the above
default value chart. K1 and K3 changes in relationship to °C if you use other scales.
K2 is the variable factor, in °C, based on the change in calibration you wish to make.
Example:
You work in °F. The actual bath temperature and display temperature do not
match. The bath temperature reads 10.25°C as measured with a certified temperature
measuring device. The display reads 50°F (10°C). The K2 factor is the difference
between these two values (certified temperature of the bath minus display temperature).
K2 is determined by the formula:
K2 = (the certified bath temperature minus the display temperature)
K2 = (10.25°C - 10°C)
K2 = 0.25°C.
The final calculation becomes::
°U = K1 (°C + K2) + K3.
°U = 1.8 (°C from the display + K2) + 32
°U = 1.8 (10°C + 0.25°C) + 32
°U = 18.45 + 32
°U = 50.45°F

°U = K1 * (°C + K2) + K3
K1 = 001.0
°U = K1 * (°C + K2) + K3
K1 = 001.0
°U = K1 * (°C + K2) + K3
K2 = 001.0
°U = K1 * (°C + K2) + K3
K3 = 001.0
