11-1-4. Bottom hold

11-1-4-1. No Zone Definition

While a Hold On command has been sent or a control input terminal Hold signal is ON, the lowest indicator value (bottom value) is
held. Sending a Hold Off command or making the control input terminal Hold signal OFF will end the bottom hold.
When holding, sending a Hold Clear command or making the control input terminal Clear signal ON will also reset the bottom value.
