4.4 Adjusting the Averager 'Response Speed' Setting

The response speed setting allows the time constant of the Land RT8A
thermometer to be adjusted to suit the application. The response speed
relates to the signal output rate and gives an average reading over the
duration of the response speed time value and can be set via potentiometer
P1 (see Fig. 7).
The averager response speed can be set to any value between 1 and 10
seconds (for 0 to 95% of the final reading).
To increase the response speed value (i.e. make the response faster):
• Remove the screw-on cap covering the control switches.
• Turn the potentiometer 'P1' anti-clockwise. When 'P1' is turned fully
anti-clockwise, the response speed is 1 second (3t)
To decrease the response speed value (i.e. make the response slower):
• Remove the screw-on cap covering the control switches.
• Turn the potentiometer 'P1' clockwise. When 'P1' is turned fully
clockwise, the response speed is 10 seconds (3t).
• Refit the screw-on cap covering the control switches.

4.5 Settings Archive

It is recommended that any emissivity or response speed settings made,
are recorded and saved to archive. This allows future reference and quick
traceability of settings without having to access the instrument to check
switch settings. When values for emissivity and response speed are set, enter
the information and values in the table below:
Serial Number
