Procedure
Analog output calibration enables calibration adjustments of the RA-1270 host monitor analog outputs 1 and 2.
Configuration selections | Configuration options |
---|---|
Output 1 mA Offset | Set the mA offset of output 1 from -2 mA to 2 mA. |
Output 1 mA Low Span | Select the low span of output 1 from 1 mA to 4 mA. The low span must be lower than the high span. |
Output 1 mA High Span | Select the high span of output 1 from 1 mA to 20 mA. The high span must be higher than the low span. |
Output 2 mA Offset | Set the mA offset for output 2 from -2 mA to 2 mA. |
Output 2 mA Low Span | Select the low span of output 2 from 1 mA to 4 mA. The low span must be lower than the high span. |
Output 2 mA High Span | Select the high span of output 2 from 1 mA to 20 mA. The high span must be higher than the low span. |
Design Range Low | Set the design range low for outputs configured for flow from 0 fpm to 10,000 fpm, or equivalent volumetric flow. The design range low must be lower than design range high. |
Design Range High | Set the design range high for outputs configured for flow from 0 fpm to 10,000 fpm, or equivalent volumetric flow. The design range high must be higher than design range low. |
Temperature Range Low | Set the temperature range low for outputs configured for temperature from -29.2°F to 129.2°F. The temperature range low must be lower than the temperature range high. |
Temperature Range High | Set the temperature range high for outputs configured for temperature from -29.2°F to 129.2°F. The temperature range high must be higher than the temperature range low. |
Output 1 Test | Enables the user to test output 1 with the offset and span settings at 0%, 50%, and 100% output. |
Output 2 Test | Enables the user to test output 2 with the offset and span settings at 0%, 50%, and 100% output. |
You can configure these settings with the RA-1270 host monitor mounted in its operating location or at a test bench in a calibration laboratory. Complete the following steps
