4. Introduction to the Magmeter-2
4.1. Summary
The Magmeter-2 provides a battery backed power supply of ±12V for most of Bartington
Instruments range of single and three-axis fluxgate sensors. It incorporates three LCDs
displaying the real-time DC field or AC field as an RMS value being measured by the connected
sensor. It also provides simple access to filtered versions of the sensor’s XYZ outputs.
Magmeter-2 has a 41/2 digit display. See product brochure DS2520 for the precise resolutions of
the unit.
4.2. Functional Description
4.2.1. Power
The Magmeter-2 will supply power as stated in product brochure DS2520 for a range of sensors.
The power is supplied from the internal, rechargeable batteries or from the plug-in power
adaptor, which is also used to charge the Magmeter-2 batteries.
Note:
When connected to the mains, the Magmeter-2 will operate without any battery cells
being installed. To install or replace defective cells, refer to
Installing and Replacing the
Internal Batteries
.
Caution:
The operating temperature range is altered during battery charging.
4.2.2. Signal Buffering
The input buffer is a differential instrumentation amplifier to minimise loading on input signals.
Note:
Output must be selected as Balanced or Unbalanced, using the
Magnetometer
Output Type Selector Switch
, depending on the type of sensor connected. See
Magnetometer Output Type Selection
