BARTINGTON INSTRUMENTS 7. PSU1 Inputs, Outputs and Controls 7.1. Back Panel Connections and Controls 1. X Signal Conditioned Output. 2. Y Signal Conditioned Output. 3. Z Signal Conditioned Output. The three BNC connectors carry the conditioned analogueue output voltages. The conditioned outputs are the magnetometer X, Y and Z signals after they have been modified by the low/high pass filters and, if a balanced output magnetometer is connected, converted to single-sided signals.. -

A. Enclosure lid retaining screw. B. Enclosure lid retaining screw. C. Earth lead fixing (do not remove) 1. Place the PSU1 on a suitable surface with the underside facing up and the two enclosure lid retaining screws nearest to you. Page 9 of 18... - Page 10 BARTINGTON INSTRUMENTS 2. Using a flat-bladed screwdriver of the appropriate size, fully loosen screw [A] to allow the edge of the lid to clear the enclosure end cap. 3. Fully loosen screw B and the lid of the enclosure will lift due to the internal springs.

Page 13: Initial Charging Of The Battery Cells
However the outputs may carry some charger noise. Note: If the PSU1 is powered by the mains charger with no batteries cells installed then the charging LED may flash. This is normal and can be ignored. -
Page 14: Connecting The Equipment
BARTINGTON INSTRUMENTS Note: The PSU1 is inherently magnetic and should, therefore, be sited as far from any magnetometers as possible. 8.4. Connecting the Equipment Caution: Connection between the magnetometer and the power supply should not be made or broken with the power supply switched on as this could cause damage to the magnetometer. -
Page 15: Troubleshooting
BARTINGTON INSTRUMENTS Note: For best results, after switching on the power, leave the PSU1 for 20 minutes for the internal temperature to stabilise, before performing any measurements. 10. Troubleshooting If the PSU1 exhibits unexpected behaviour, please check possible causes in the following table:... -
Page 16: Care And Maintenance
Return PSU1 and sensor to Bartington Instruments for repair If the solutions suggested above do not fix the fault, contact the Bartington Instruments helpdesk. 11. Care and Maintenance The PSU1 requires no routine maintenance. There are no user serviceable parts. -
Page 17: Fuses
BARTINGTON INSTRUMENTS 11.1. Fuses As a safety feature the PSU1 is fitted with a thermal fuse. If the PSU1 overheats, which could occur as a result of the fitment of incorrect battery cells, the charging circuit will be permanently isolated. The PSU1 must be returned to Bartington Instruments for checks and repair. - Page 18 T: +44 (0)1993 706565 Bartington Instruments Limited The specifications of the products described in this brochure are subject to change without prior notice.
