attached to a mounting plate, which is retained by four screws to the theodolite telescope.
Gasket sealing is provided to prevent the ingress of moisture.
The instrument is supplied with the probe aligned parallel to the optical axis of the theodolite to
within 10 seconds of arc.
A high flexibility cable connects the probe to the electronics unit. If the cable is not already fitted
to the cover, follow the instructions for fitting in
Probe Cable Repairs below.
4.3. Electromagnetic Compatibility
The Mag-01H instrument contains no high frequency electronics likely to cause emissions which
could affect other apparatus. The design, including the use of a rechargeable battery (charged
from a mains adaptor) and the decoupling of internal power supplies, is intended to produce
minimal emissions. Other equipment operating in the area is therefore unlikely to be affected.
Note: The unit itself is also unlikely to be affected by interference from other equipment in
the normal operating environment. However, the probe is designed to measure magnetic
fields and therefore is susceptible to electromagnetic interference. Operation close to a
high frequency source of radiation should be avoided. Interference is indicated by instability
in the reading when the probe is maintained in a fixed position.
