5.3.3 Test sockets
Thanks to the test sockets integrated into the transformer part front
panel, it is possible to measure the ionisation current without
interruptions. A customary amperemeter with a measurement
range from 0 - 50
μA DC shall be used for the measurement.
The test sockets are designed for short-time measurements for
flame signal optimisation only. A permanent connection of
measurement devices is not permissible.
