This is a signal processer with bandpass filters, cutoff frequencies of 20 500 Hz, instrumentation preamplifier (20-fold gain), differential amplifier with bipolar input, and common mode rejection > 100 dB.
Signals were amplified (×50,000) and digitised in two ways: (1) In nine cases (Rome and Berlin) we used a custom-made, 9 V battery-operated high-impedance amplifier (INA128 instrumentation amplifier, Texas Instruments, Inc., Dallas, TX, USA).
Coagulation times were measured upon addition of a contact activator (SynthASil, Hemosil) and CaCl2 on a ACLTOP700 instrument (Instrumentation Laboratory).

A total of 19 instrumentation technicians were required for overtime maintenance activities.
A total of 23 instrumentation technicians were required for routine maintenance activities.
For this aim, 8 instrumentation sections were modeled using FLAC3D 5.0 and the real topography was determined.
