| #34 Checking IRt/c Ambient Temperature |
| In many installations, it may not be clear whether cooling is required, and it may not be easy to obtain the temperature of the environment experienced by the IRt/c. The IRt/c itself will tell you what its own temperature is, by using the procedure illustrated below. T |
|
| he basic method is to temporarily "blind" the IRt/c using aluminum foil, so that it can only see itself. The temperature that it produces is then its own temperature only. |
| Before running this test, be sure to check for leakage current offsets as described in the manual. |
 |
Place IRt/c close to controller and cover IRt/c with aluminum foil. |
|
Wire connections in standard fashion. |
|
Short the input to obtain the leakage current offset (see Manual). |
|
Adjust OFFSET, ZERO, or LOCAL to correct the offset as required. |
|
Install IRt/c in operating environment and monitor the display temperature. |
|
If below 200 °F (100 °C) no cooling is required. |
