removed. Disconnect the power to the mass flow meter, and cables to the
D-connector. Remove the three screws at the base of the can and remove
the top jack post of the D-connector. Remove the can. The can must be
replaced before returning the unit to service.
Refer to Section 2-6 for the proper electrical hook-up. Refer to Figure 3-5

A 0-5 Vdc flow signal is always available. The current signal output is
jumper-selectable for either 0-20 mAdc or 4-20 mAdc. Jumpers J3 and J4
( blue ) must be in the upper position for 0-20 mAdc output and in the lower
position for 4-20 mAdc output.
NOTE: Both J3 and J4 must be in the same position. Jumpers J3 and J4
do not affect the voltage output.
