Optical Beam
Figure 2-3 Measurement of optical beam by using
MAX-Hold function
Measurement of an optical beam depends on the angle
at which the sensor is held, as shown in Figure 2-3. To
measure the optical beam accurately, set the indication
unit to W, press the key, and execute the MAX-
Hold function. The maximum measured value can
then be obtained automatically by moving the sensor
in various directions.
2.11 Relative Value Measurement
If the indication unit is set to dBm and the key is
pressed, the latest measured value is used as a refer-
ence (0 dB) for subsequent measured values. The oper-
ations required for this relative value measurement are
given in the table on the next page.
