The indicator has a switch that is suited to subtract from the displayed value typical resistance
for used ED 100i chokes connection. When connecting 2 or 3 chokes, set the switch to „
∼

If the connection is applied through one choke, set the switch to „
∼
1”. Setting the switch in the
middle position disables this function
