5 Unit Support Data
5.1 Calibration Data
Calibration Tests:
o Calorimeter (CAL) – Calibrates the TEM measurement of the CAL HV current
against an
external measurement and logs the internal current measurement as a function of
voltage.
o Tracker (TKR) – Calibrates the TEM measurement of the TKR HV current against
an
external measurement and logs the internal current measurement as a function of
voltage.
o TEM/TPS – Calibrates the TEM measurement of the tower current against the
power
supply measurement.
Calibration constants were deteremined using LAT-TD-04085-02, CAL HV Current Calibration 5.4.1, TRK HV Current Calibration 5.4.2 and TPS current cablibration 5.4.3
