Combined Calibration Specifications
The sensor head (735221) and TB200 Optical Powermeter (735201) are calibrated
together. If you selected the combined calibration option at the time of purchase,
the electrical/optical characteristics of the sensor head are as given below (suffix
code -CA1 or -CA3). The sensor head calibration data is written to the TB200
Optical Powermeter (735201), and the model of the sensor head becomes that
of the main unit (735201).

* Uncertainty when only sensor head is sold. For details on
uncertainty when the integrated calibration option is applied, refer
to the “Remarks” column of the Model and Suffix Code table.
Note 3) Compensation values for this sensor head are provided in the TB200
Utility CD.
These performance values are for when this data is uploaded to the
TB200 Optical Power Meter for use.
