Setting the Absolute Comparator
To set the Absolute Value Comparator, following the procedure below:
1. Select either the upper or lower comparator limit.
To input an upper limit, press [HIGH]
To input a lower limit, press [LOW]
2. Input the BIN No.
After the [HIGH] or [LOW] key is pressed, the BIN LED will begin to flash. Use keys [1]~[9]
to designate the number.
3. Input a limit value for DISPLAY A
After selecting the bin number, use the cursor to highlight DISPLAY A.
Enter the 5-digit upper or lower value using the keys [1]~[9]. When this is complete, the
decimal point will flash.
Press [DP] to move the decimal point to the position of the setting value.
Use the cursor [Ź] to highlight the unit. Here, each time [UNIT] is pressed, the unit will
change. Designate the unit for the Nominal value.
4. Input a limit value for DISPLAY B
When the setting for DISPLAY A is complete, use the cursor [Ź] to highlight DISPLAY B.
Enter the 5 digits, decimal point and unit as done for DISPLAY A.
If the setting is a negative value, use the cursors keys, [Ź] or [Ż] to highlight the 1
st
digit
of DISPLAY B.
Press [-] to negate the value.
5. Finalize the Comparator Settings
If defining an upper limit, press [HIGH] to complete the setting.
If defining a lower limit, press [LOW] to complete the setting.
To input settings for other bins, repeat the steps above.
6. Invalidating the DISPLAY A or DISPLAY B Comparator settings.
To invalidate the settings, take the cursor, [Ź] or [Ż], to any digit location in DISPLAY A or
DISPLAY B. Then press [IGNORE] to invalidate the settings of DISPLAY A or DISPLAY B.
NOTES:
The comparator can only be set using panels [1]~[9]. [0] is not used.
The above procedure applies only to the Absolute Value Comparator. The procedure for
setting the Percent Comparator is different. Before attempting to set the Absolute
Comparator limits, verify that the 3550 is in the Absolute Comparator Mode.
After setting the limit values for the comparator, the measurement parameters for
DISPLAY A and DISPLAY B cannot be changed. The measurement parameters must be
defined before the comparator is set.
For DISPLAY B, there are no units for D,Q, or LJ.
