3.3 Preparing for field measurements
3.3.1 Test setup
The following are part of the complete test setup for measuring a field:
•
The basic instrument
•
The B field probe (cross sectional area 100 cm
2
)
The instrument uses an external isotropic magnetic field probe and is
also suitable for standards-compliant measurements in non-
homogeneous fields.
Note: Persons or objects should not come between the probe and the
radiation source during the measurement.
3.3.2 Connecting / disconnecting the B field probe
The multi-pin connector socket for the B field probe is located at the top of
the ELT-400. The field probe is secured by means of a sliding locking sleeve.

Connecting the field probe
1. Place the probe on the basic instrument so that the red marks on the
plug and socket point in the same direction.
2. Hold the field probe by the black shaft and press it into the basic
instrument until the locking sleeve clicks into place.
The instrument detects the probe automatically.
