Method 2, for Load Resistance < 250 Ohms

Refer to Figure 4-2and the following steps to connect the HART communicator to a signal line with less than 250 ohms 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.

1.At a convenient point, break the oxygen analog output 4-20 mA signal line and install the optional 250 ohm load resistor.

2.Plug the load resistor into the loop connectors (located on the rear panel of the HART communicator).
