Quick start
When MJK 713 is powered up for the first time, a quick 
setup sequence will be initiated that will guide you 
through the following basic settings needed for most 
installations:

1:  selection of primary device / flow calculation 

formula

2:  max. flow range
3a:  ultrasonic transmitter distance 

(applies to MJK 713 2500 / 
System Package 1 only)

3b:  hydrostatic sensor range 

(applies to MJK 713 3000 / 
System Package 3 only)

After these initial settings has been made, MJK 713 will 
automatically begin to measure flow. If you wish to take 
advantage of the flow converter’s many other advanced 
functions, such as flow proportion sampling, the remain-
ing sections of this manual will help you to configure the 
unit.
