Connecting the 830 in place of a transmitter

Connect the PIE 830 in place of the transmitter. The 4-20 mA

loop connects to the mA jacks of the 830 and the sensor (or

pressure module) connects to the other jacks of the 830.

Note: With LOOPSCOPE on the 830 occasionally performs a

test on the loop. During this short test the loop mA signal will be

affected.
