An instruction manual is presented for the electromagnetic log voltage simulator. The electromagnetic log voltage simulator is designed to assist in the adjustment, calibration, and troubleshooting of the underwater electromagnetic log system by providing a calibrated voltage which can be directly connected to the indicatortransmitter. The electromagnetic log voltage simulator can be substituted for the rodmeter on all shipboard installations of the electromagnetic log system regardless of type or manufacture. The manual contains complete operating instructions and connection diagrams required for shipboard use. Author
