Appendix F: Detector Calibration
This procedure performs alignment of the SteppIR SARK-110’s internal measurement circuits. This
operation is done once at the factory and it is not necessary for the user to repeat it, but the
procedure is detailed for completeness.
The following test loads are required: 0, 50, 100, and 200-ohm. These loads need to be precise and
stable and should be properly implemented in order to have the least possible stray impedance.
Before performing this operation it is strongly recommended that the file containing the factory
results,
detcalib.dat
, is backed up to enable a restore, if needed.
The calibration operation is available at «Setup»
«Calibration»
«Detector Calibration».
The calibration procedure is as follows:
Connect the short load.
Press the appropriate button to continue, or
to exit.
