Strobe control
Strobe control is selected with the
STROBE-CONTROL
menu item, which enables or disables the
use of digital output #4 as a binning strobe signal. If enabled, the strobe signal is set TRUE for
greater than 10 microseconds after all limit tests have been performed on a new reading. The FALSE
to TRUE transition can be used to trigger an external device handler to check digital outputs #1-3 for
sorting parts into bins.
When external device handler "binning" is enabled from the front panel or with the bus command
:CALCulate3:BSTRobe:STATe ON, the binning strobe signal is set to
FALSE
. When "binning" is
disabled, the strobe signal is left unchanged.
DISABLED: Use this selection to disable strobe control.
ENABLED: Use this selection to enable strobe control.
Pass pattern
The
PASS-PATTERN
menu item allows you to program the on/off states of the digital output lines for
when all limit tests pass. Note that when the binning strobe is enabled, digital output line #4 cannot be
used.
Selecting
PASS-PATTERN
displays the digital output pattern that occurs when all limit tests pass. To
change the pattern, use the cursor keys and the
RANGE
keys. The
RANGE
keys toggle the
parameter values between
OFF
and
ON
.
