User Calibration Curve File Format
Sensor calibration curves may be sent to any Cryo-con instrument using a properly
formatted text file. This file has the extension .crv. It consists of a header block, lines
of curve data and is terminated by a single semicolon (;) character.
The header consists of four lines as follows:
Sensor Name: Sensor name string
Sensor Type: Enumeration
Multiplier: Signed numeric
Units: Units of calibration curve: {OHMS | VOLTS | LOGOHM}
The Sensor Name string can be up to 15 characters and is used to identify the
individual sensor curve. When downloaded to a Cryo-con instrument, this name
appears in the sensor selection menu of the embedded web server and will appear on
all sensor selection fields on the front panel.
The Sensor Type Enumeration identifies the required input configuration of the input
channel. For the Model 24C, selections are: DIODE, PTC100, PTC1K, NTC10uA,
TC70, NONE and ACR. These configurations are described in the section titled
Supported Sensor Configurations.
