Page 14: Using The Thermometer
Thermometer User Guide Using the Thermometer It is recommended that the ‘Emissivity’ and ‘Response Time’ controls are set to match the requirements of the particular measurement location before installation. This is particularly relevant if the thermometer is to be used in a location which is difficult to access and/or used in conjunction with a jacket and back cap. -
Page 15: Adjusting The Emissivity Value
The emissivity can be set in the range 0.10 to 1.00 in steps of 0.01. The CDA is supplied with the emissivity factory-set to 1.00. The Emissivity value is set using switches SW1 and SW2. See Fig. 10. -
Page 16: Adjusting The Averager Response Time
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. -
Page 17: Noting 'Emissivity' And 'Response Time' Settings
User Guide Thermometer 4.4 Noting ‘Emissivity’ and ‘Response Time’ Settings It is advisable to make a note of the settings for ‘Emissivity’ and ‘Response Time’, once these settings have been determined and verified. Each time a re-adjustment is made to the settings, make a note in the table below, using the spaces provided. -
