4.3 Adjusting the Averager Response Time
The response time control allows the time constant of the thermometer to be
adjusted to suit the application.
NOTE
For longer time constants (e.g. to mimic thermocouples), an averaging
meter is advised. Suitable units provide 0 to 999 seconds of response, 4
to 20 mA retransmission output and also power to the CDA .
For further information, contact Land Instruments International.
To adjust the Averager Response Time function, use the potentiometer P1
(see Fig. 10). The Response Time value can be set to between 1 and 10
seconds (for 0 to 95% of the final reading).
For a faster Response Time:
Turn the potentiometer P1 anticlockwise. If P1 is turned fully
anticlockwise, the ‘Response Time’ is at the fastest setting (approx. 1
second).
For a slower Response Time:
Turn the potentiometer P1 clockwise. If P1 is turned fully clockwise, the
‘Response Time’ is at the slowest setting (approx. 10 seconds).
