1Portable Dew Point MeterDaily maintenance after use (3 minutes to complete)
Cleaning the casing: Use a dry soft cloth to wipe off dust and oil stains on the surface of the instrument to prevent liquid from seeping into the interface.
Dry sensor: After measuring high humidity gas, turn on the device and run it without load for 5 minutes, or blow the sensor interface with dry nitrogen to prevent moisture residue.
Check battery level: Charge in a timely manner to avoid storing in a depleted state; When not in use for a long time, charge once a month.
2、 Weekly routine check (completed in 5 minutes)
Interface sealing: Check whether the sealing rings of the air inlet and outlet are intact, whether they are aged or damaged, and ensure that the seals do not leak.
Screen and buttons: Wipe off screen stains, test button responsiveness, and avoid button sticking.
Calibration reminder: Check the validity period of the instrument calibration. If it is about to expire, arrange calibration in a timely manner (no need to operate by yourself, just contact a professional organization).
3、 Monthly in-depth maintenance (completed in 10 minutes)
Sensor cleaning: If the measurement data drifts or the response slows down, gently wipe the sensor probe with a dedicated cleaning cotton swab (do not use alcohol, water, or other liquids) to remove surface impurities.
Cable inspection: Check whether the charging cable and data cable are damaged, whether the interface is loose, and avoid poor contact.
Storage environment: Ensure that the instrument is stored in a dry, ventilated, and non corrosive gas environment, avoiding direct sunlight and high temperature and humidity places.
4Portable Dew Point MeterPrecautions (Key Reminders)
Prohibited from use in flammable, explosive, and highly corrosive gas environments to avoid damaging instruments.
Do not disassemble the internal components of the instrument by yourself, and only operate the externally accessible parts during maintenance.
If the instrument malfunctions (such as inability to turn on or abnormal data), contact after-sales service in a timely manner and do not blindly repair it.
