Variable Documentation

LTC_defaultConfig

Default LTC configuration values. This database is used if the LTC_DB module is not loaded. There are two PDU tables. One for primary PDU and one for redundant PDU. Each record of these tables provides definitions for each temperature read from the PDU. It is ordered by PDU group for easy use when working with PDU hardware. The PDU group and ADC number for each sensor is built into this table. The sensors are associated with a heat pipe as defined by the hardware configuration.

LTC_rtdCnvTbl

Counts to temperature convertion table for RES/RTD type sensor. Generated based on PDU/RTD circuit and vendor (Goodrich Model 0118MF) resistance-temperature relationship table.

LTC_rtdFltDf

Initial value: { 10, { .1*CFSCL, .1*CFSCL, .1*CFSCL, .1*CFSCL, .1*CFSCL, .1*CFSCL, .1*CFSCL, .1*CFSCL, .1*CFSCL, .1*CFSCL, } } Smoothing filter definition for RES/RTD type sensor. Long moving average filter to handle the excessive noise from the RES sensor electronics.

LTC_thrmCnvTbl

Counts to temperature convertion table for RIT/thermistor type sensor. Generated based on PDU/thermistor circuit and vendor (YSI 44900) resistance-temperature relationship table.

LTC_thrmFltDf

Initial value: { 6, { .5238*CFSCL, .3810*CFSCL, .2381*CFSCL, .0952*CFSCL, -.0476*CFSCL, -.1905*CFSCL } } Smoothing filter definition for RIT/thermistor type sensor. Default built-in RIT sensor filter definition.
