Method 1, for Load Resistance 250 Ohms

Refer to Figure 4-1and the following steps to connect the HART communicator to a signal line 250 ohms or more of load resistance.

Do not make connections to the HART communicator's serial port, 4-20 mA signal lines, or NiCad recharger jack in an explosive atmosphere. Explosions can result in death or serious injury.

Using the supplied lead set, connect the HART communicator in parallel to the OCX 8800. Use any wiring termination points in the oxygen analog output 4-20 mA signal line.
