This document provides instructions for setting up tank radar and radar master software: 1. Connect the Hart communicator to the radar and select basic setup to input measurements like tank dimensions and material properties. Offset the radar level reading to match the hand gauge measurement. 2. Install a 250 ohm resistor in the radar power supply circuit for HART communications. Connect the Hart communicator leads on either side. 3. Open the radar master software, set the communication settings to connect to the HART communicator port, and scan to find the instrument. Then use the setup wizard to input the radar configuration.
