BARTINGTON INSTRUMENTS See Figures 4 and 5 for circuitry diagrams. See Introduction to the Probes for the principles of fluxgate operation. The alternating field used in the operation of the probes is driven by a high purity alternating signal (the excitation signal) from the probe excitation oscillator to the excitation winding. -

Caution: Care must be taken when disconnecting the battery, if unsure please ask a qualified service person or seek advice from Bartington Instruments. Disconnect the battery in the following way:... -
Page 11: The Autoranging Display
BARTINGTON INSTRUMENTS Ensure that the battery is fully charged. In this way it will not degrade for periods of non-use up to 1 year. ii. Open the instrument case by removing the two retaining screws located at the edges of the instrument base. Remove the cover of the instrument, leaving the front and rear panels located in the base. -

Proximity Effects Note: Mag cryogenic probes can only operate in close proximity to each other if they are mutally orthogonal. Otherwise, to avoid interaction, no two Mag cryogenic probes should be operated within 10mm of each other. -
Page 15: Operating Instructions
BARTINGTON INSTRUMENTS 6. Operating Instructions Refer to figures 1, 4 and 5. 6.1. Switching On Connect the probe selected to the probe socket and switch on the magnetometer. Note: The plug locking mechanism requires that the outer shell of the plug is retracted (towards cable) during insertion and removal. -

Power Supplies and Battery Charging. Remove the two case retaining screws in the base of the instrument and remove the top cover. Disconnect the battery leads (Mag-01) or the battery connector (Mag-01H) and fit a replacement battery. Re-connect. 6.6. Electromagnetic Compatibility The Mag-01 and Mag-01H instruments contain no high frequency electronics likely to cause emissions which could affect other apparatus. -
