Note:

 Provides useful supporting information on how to make better use of your purchase.

2. Safe Use

WARNING: 

The Mag-01 and Mag-01H can be powered by mains electricity, either in 

operation or during their battery charging cycle, and contain uninsulated parts. Ensure that 
the unit is properly earthed at all times. Only properly trained personnel should carry out 
procedures described in this manual which require the casing to be opened.

WARNING: 

These products are not qualified for use in explosive atmospheres or life 

support systems. Consult Bartington Instruments for advice.

3. Introduction 

The Mag-01 and Mag-01H magnetometer systems are intended for the measurement of 
relatively weak (nT), slowly varying (10Hz max) magnetic fields in one axis.

The system comprises one of a range of compact fluxgate probes connected by a cable to a 
compact electronics unit (the magnetometer).
