Settings for Use of CA12E in Fahrenheit
"."-
The default temperature read-out of the CAI2E is in Celsius ("C).
To change it to Fahrenheit ("F), it is necessar to proceed as fallows:
Changing the temperature unit setting to Fahrenheit
The following features are available depending on the settngs of the DIP switches above the battery
holder, which can be accessed by removing the cover from the back of the instrument.

For more information on DIP switches, see "Section 7. Other Features" of User's Manual
(1M CAl2E-OI E).

1 2
1: Reference junction compensation by the intemal RJ sensor
2: Temperature (Unit ofTemperature)
3: Setting of thermocouple standard (OFF: ITS90/0N: IPTS6B)
4: Disable automatic power off
7.2 Temperature (Unit of Temperature)
Use DIP switch 2 to select the unit of temperature.
OFF: °C
ON: OF
The conversion from Celsius to Fahenheit is performed using the equation
Fahenheit temperature = 1.8 X Celsius temperature + 32

'2: According to JIS e 1604-1997 (Reference Resistance Table)
International Practical Temperature Scale of 1968 (IPTS68) for PT100 reference resistance
IPTS68 for PT100 is -200 to +650oe.
'3: The Te generation accuracy does not include the RJ accuracy.
The sensor output accuracy must be taken into consideration when output compensation is determined based on the RJ temperature
(output compensation performed every 4 seconds).
'4: When it is calculated according to the Reference Thermo-electromotive Force Table, the TC measuring accuracy includes the RJ accuracy
(TC accuracy added).
The terminal temperature must be stable.
'5: Three-wire mèasurement
'S: Excitation current for generation: 0.5-2 mA; Excitation current for measurement: approximately 2 mA
When the excitation current is 0.1 mA, 0.05% + 1°C (0.40) is added, and the maximum input capacitance of the device under calibration is
0.1 flF.
