High Clamp, Low Clamp Value
The High Clamp value will be ignored if HCE is not set.
•
• The Low Clamp value will be ignored if LCE is not set.
If you set the High or Low Clamp beyond the Limit for the specific
Range/Format setting, the output is internally adjusted to the Limit values. In this
case, the Limit value determines the Over or Under Range Alarm trigger if HCA
or LCA is set respectively (assuming HCE or LCE is set).
