The upper limit (= 10 V) is set via the parameter
"Exponent upper limit” in whole decades. The lower
value is always 0 (leak rate), which corresponds to 0
V output voltage.
This setting is for both analog outputs, if an
appropriate output function is selected. Depending on
the selected leak rate unit there is a different absolute
limit.
The selected range can be additionally narrowed by
the limits, which is valid for all interfaces.
