About Reading Sensitivity Level

When this device is operating in the SR-600 mode, it is possible to set the reading sensitivity level
with a command from a computer.
The reading sensitivity level ranges from 1 through 16, with Level 1 having the maximum reading
sensitivity and Level 16 having the minimum reading sensitivity.
The table below compares the reading sensitivity levels of this SR-1800 device with the
conventional SR-600 device.

*1: The above sensitivity levels are the approximate values for marks filled in using SEKONIC
Corporation measurement methods.
*2: Both devices have different reading methods, so there are differences in levels depending on the mark.
*3: If SW3-1 and -2 are set to "SR600MODE" and used in the compatible mode, sensitivity levels
must be checked by the user.
