6.4.2 Tact check mode
The tact check mode is used to count how many scans the BL-600 Series can
accurately read (decode) while reading a moving bar code.
This mode is useful for the following case:
● Testing the line speed that can be expected before actually implementing the
BL-600 Series on the line
A large decoding number shows that the BL-600 Series can reliably read the
bar code (capable for the line speed).
Note: The tact check should be performed on a moving bar code.
■ Starting method
There are four methods to start the reading rate check mode. Select one of the
following for your convenience.
• Press the TEST switch of the BL-600 Series.
• Use the [[Monitor]] screen of the setup software. ➮ See page 62.
• Use the bar code display interface BL-V35E. ➮ See the BL-V35E User’s Manual.

The following instruction uses the TEST switch to start/quit the reading rate check.
All other operations are the same for the other starting methods.
