P125 High mA Trim

This parameter allows you to “calibrate” the

Zenith to the

High mA Input

from the device being used. If the expected high value, from the device
connected to the mA Input, is not displayed, then you can trim it using this
parameter.

Important Notice

When using the auxiliary input, all settings relating to measurement should be
entered in relation to level i.e., zero (empty) to 100% (full) and not distance. This also
means that the device you are connecting should provide an input that will change
with level.
