2—1 Chapter 2 Introduction This section is the reference for the ENVI PRO instrument itself. You will find all the information you need to know about setting up the unit for field use, its operation, maintenance and trouble-shooting. It is divided into eleven chapters with the information flow from chapter to chapter following a natural progression, as shown in the following table: Chapter Description 1. Preface Features, upgrades and options. 2. Introduction Outlines what the instrument can do. 3. Preparing Describes the assembly of the system for use. 4. The This chapter is about the instrument itself. Instrument 5. Operating Displays 6. Setting Up 7. Operating 8. Date Output 9. Maintenance Describes the various display screens. Describes how to initialize the ENVI PRO and program it for different modes of operation. Guides you through typical instrument operation using basic, search and advanced configurations in a WALKMAG and a Stopand-go type of survey. Shows examples of data output formats and explains how to dump the acquired data. Describes basic maintenance, trouble-shooting and repair. 10. Reference Contains the technical specifications, instrument parts list and warranty information. 11. Applications Magnetic Surveying Overview and basic magnetic theory Cold Boot Please read the section “First time operation” on page 6—1 so that you will know how to do a cold boot of the instrument. This is needed the first time you use it, whenever you wish to change operating configurations or after the batteries have been removed for more than 10 minutes. Instrument Overview The SCINTREX ENVI PRO is an easy-to-use, lightweight, battery-powered, portable magnetometer. The magnetometer is a total field instrument using the proton-precession technique to measure the local magnetic field. Optional magnetometer upgrade kits allow the instrument to be used as a gradiometer or as a base-station. The standard configuration has the sensor mounted in a backpack mode permitting rapid data acquisition in the trademarked WALKMAG mode. Measured data is stored in the ENVI PRO console memory along with the coordinates where the measurement took place. You can P/N 788715 Rev. 0
Introduction also enter descriptive notes of up to 32 characters at any station. The data can be displayed either numerically or graphically for quick inspection of the data quality and spotting of anomalies. Data can also be recalled from memory for visual inspection, dumped either to the serial port (RS-232) of a computer or directly to a printer. You can also automatically correct your magnetic data for diurnal variations when another ENVI PRO is used as a base-station or when you conduct your survey in the TIE mode. The operating modes of the ENVI PRO can be manual, semi-automatic or fully automatic. In the WALKMAG (walking magnetometer) mode, data are acquired and recorded at rates of up to two readings per second, as you walk at a steady pace along the survey line. At desired intervals, you trigger a station marker by pressing a single button and the co-ordinates are automatically assigned to the recorded data. You can even introduce delays in the automatic recording to compensate for walking over rugged terrain. The ENVI PRO comes with a Single-frequency GPS antenna allowing the user to acquire non-differential positional data along with the magnetometer data. Being a non-differential receiver, the positional accuracy is of the order of a few meters, which is sufficiently accurate for most magnetometer surveys. Should you require more accurate position and sensitivity, you should consider our NAVMAG cesium vapor magnetometer. 2—2 P/N 788715 Rev. 0
