3.3.7 Evaluating the Cleaned Probe
Note: All new probes are calibrated at the factory, and therefore, no evaluation is required after installation.
1. Reconnect the probe cable to the transmitter module and measure the ambient air dew point. Make sure to
measure the same ambient air as measured during removal of the transmitter.
2. Compare the two ambient air readings. If the new ambient air reading is within ±2°C (±3.6°F) of the first reading,
the cleaned probe is properly calibrated and normal operation may be resumed.
3. If the probe is still not reading the ambient air accurately, repeat the cleaning procedure using soaking times
that are five times those used in the previous cleaning sequence. Repeat the cleaning cycles until two
consecutive ambient air readings are identical.
If the above cleaning procedure does not result in accurate readings, contact Panametrics Technical Support for
assistance.
