HAM-ISI - L4C huddle test at reception - Shipment #3880
The set of 6 horizontal L4Cs received in shipment load #3880 were huddle tested this morning,
We noted a few points that we need to be careful about in order to perform this test correctly:
- Level the instruments
- Have them properly seated (check that they do not rock)
- Direct the instruments towards the same direction
Spectra are attached.
