TAM-A Type 705/1 and TAM-D Type 705/2
A low-pass filter is arranged before the pulsatile signal output to smooth the signal wafeform.
The filter action can be selected on the FILTER (Hz) switch between 30, 100 and 300 Hz (older version 1, 100and
300 Hz). The stated frequency refers to the frequency limit for -3dB amplitude loss. Normally the filter setting 300
Hz should be selected. Depending on the type of measurement signal the filter can if required be switched to 100
or 30 Hz. Always check how the filter action alters the shape of the signal.
On cardiovascular pressure measurement always use the filters 100 or 300Hz. On respiratory
and tisse experiments with slow smooth muscles you can use the 30Hz filter position.
The filter should never alter the signal in its amplitude !!!
8. Filter 30 - 100 - 300 Hz
9. Maintenance notes
Any splashes of salt solution should be removed immediately with a cloth in order to prevent
corrosion damage to the metal parts, the connectors and the electronics.
For cleaning the front panel, connectors and cables never use scouring powder or cleaning agents
which attack plastics or aluminium.
Any dust should be removed with a lint-free cloth or with a fine dust brush.
Heavier dirt can be removed with soapy water or a domestic cleaning agent, using a soft cloth.
Then wipe up with clean water. Never allow any liquid to find its way inside the instrument or into
switches or sockets.
Any spots on the aluminium front panel can be removed with an ordinary plastic rubber.
The interior of the module does not require any servicing or cleaning.
