Operator's guide

1.1 Response options

The 40T can be supplied with a response which is flat to velocity from 50 Hz to

any of 0.1 Hz (10 s), 0.050 Hz (20 s) or 0.033 Hz (30 s).

If you do not require high-frequency data, a low-pass filter may be installed at a

frequency (below 50 Hz) that you specify.

Standard 40T instruments output signals representing ground velocity on three

pairs of balanced differential lines. An option is available which provides a

second, parallel set of outputs at higher gain. The high-gain outputs have a

sensitivity nominally 10 times higher than the standard (low-gain) outputs.
