GATE LOGIC Setting the gate logic
In this function you can activate the gate and select
the criteria for triggering the gate alarm. The following
settings are available:
• OFF: The gate is disabled. The gate bar is not
displayed.
• POSITIVE: The gate is enabled. When the signal
exceeds the threshold that was preset in a-THRESH,
the two LEDs will flash alternately.
• NEGATIVE: The gate is enabled. When the signal
falls below the threshold that was preset in a-
THRESH, the two LEDs will flash alternately.
• MEASURE: The gate is enabled. However, there is
no alarm with threshold violation.
H Note:
You can select either POSITIVE, NEGATIVE or MEA-
SURE for digital thickness measurements.
A Attention:
Both gates only evaluate within the visible part of the
display range. If there are gates or parts of gates out-
side the visible part of the display range, then a gate
evaluation will not be made there.
Operation:
– Highlight the center function group in the left function
table with I.
– With M select the required gate setting.
