Note:
If possible, select a setting which produces three places of decimal resolution on the
display.
6.4. Using the Sensitivity x10 Control (Mag-01H only)
With this set to x10, all displayed values must be divided by 10.
Example:
In a field with strength 11.185
μ
T, on the x10 setting the display will show 111.85. Divide
this value by 10 to get the correct measured result of 11.185
μ
T.
6.5. Battery Replacement
Should the internal battery fail to provide at least 10 hours continuous use after two years
service, it will need replacing. The instrument can be returned to the company’s agents if they
provide service, or to Bartington Instruments in the UK. Alternatively customers can carry out
battery replacement themselves as follows.
6.4.1. Instructions for Battery Replacement
Open the case in the manner described in
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. The design, including the use of a rechargeable
battery that is charged from a mains adaptor, and decoupling of internal power supplies, is intended
to produce minimal emissions. Other equipment operating in the area is therefore unlikely to be
affected.
The unit is also unlikely to be affected by interference from other equipment in the normal
operating environment. However the sensors, being designed to measure magnetic fields, are
susceptible to electromagnetic interference, and operation close to high frequency sources of
radiation should be avoided. Interference is indicated by instability in the reading when the probe
is maintained in a fixed position.
