Gauss- / Teslameter

3 Introduction

3.1 General

The FH 55 Gauss-/Teslameter is measuring instrument that provides measurements of AC and
DC magnetic fields using Hall sensors. The unit is designed for wide range, high accuracy, and
ease of use. The instrument is operated by front panel keys or the RS232 interface. Most user
features are one pushbutton away. The settings are stored if the instrument is switched off. The
FH 55 features:
• Magnetic Field Measurement:
− High accuracy with high resolution
− Auto range function
− DC or AC field measurement
− Individual linearization of Hall Probes
− Temperature compensation of Hall Probes
• Alphanumeric Display:
− ¾ -digit display, 1 part in 3000 resolution on all ranges
− Liquid crystal display.
• Other Major Operating Functions:
− Display Filter
− Tesla, Gauss or Ampere/Meter units
− Max Hold, Min Hold
− Peak measurement
− Relative Reading
− Limit function
• Output:
− Serial Interface (RS-232C)
− Monitor Analog Output
• Probe Compatibility:
− Standard Probes with small active area – 3 mT to 3 T Full-Scale Ranges
− High Field Probes to 30 T Full-Scale Range
− High Sensitivity Probes – 30 µT to 300 µT Full-Scale Ranges
If you have just received your new FH 55, please proceed to the next chapter and become
familiar with the installation instructions. Complete and detailed instrument operational
information is contained in chapter Functions. Chapter Probes contains important information
concerning the choice and operation of the Hall probes. The chapter Remote Operation
describes the use of the serial interface. Basic service hints and the rear panel connector
