1、 Daily operation and inspection

1. safe placementThe instrument should be placed in a safe place to prevent it from being dropped and to avoid severe shaking to prevent damage to the internal sensors.
2. Avoid corrosive gasesDo not measure corrosive gases to avoid damage to the instrument.
3. Adjust gas flow rateWhen adjusting the gas flow rate, the control needle valve should be slowly opened to indicate a flow rate of 0.5-0.6 liters per minute. If the flow rate exceeds 1 liter/minute, the LCD will display a prompt indicating that the flow rate has exceeded the limit. At this time, the flow rate should be reduced to the limit value to prevent damage to the electronic flow sensor.
4. Charge in timeIf the dew point meter is powered by batteries, it should be charged promptly after a whole day of use. When charging, simply connect the power cord to a 220V socket without turning off the power switch. The instrument will automatically charge, and the charging time is usually more than 5 hours.

2、 Equipment cleaning and maintenance

1. Clean the instrument casingWipe the instrument casing with a clean and soft cloth, avoiding the use of damp cloths or solvents containing corrosive substances.
2. Clean the sensorRegularly clean the dust and dirt on the surface of the sensor with specialized cleaning agents or dry compressed gas to ensure measurement accuracy.
3. Avoid contact with water vaporPrevent moisture, oil stains, or other chemical substances from directly contacting the sensor to prevent corrosion or condensation from affecting measurement accuracy.
4. Clean the sampling pipelineEnsure reliable connection of the sampling pipeline, regularly clean the sampling pipeline, and prevent measurement errors caused by impurities absorbing or releasing moisture inside the pipeline.

3、 Regular calibration and inspection

1. periodic calibrationRegularly calibrate according to the instructions to ensure accuracy. It is generally recommended to calibrate every six months, but the specific calibration frequency and method should be determined according to the instrument model and manufacturer's requirements. If necessary, contact professionals or send it back to the manufacturer for precise calibration.
2. Check the probeThe probe is the core component for measurement and should be regularly cleaned and calibrated. The interval between verification periods is generally one year. When verification is needed, you can contact the manufacturer or professional personnel.
3. Check the power cord and connecting circuitEnsure that the power cord and connecting wires are secure and free from looseness or damage, and repair or replace them promptly if necessary.
4. Check the protective cover and filterIf there is any damage or contamination, it should be replaced in a timely manner to protect the internal components of the instrument.
5. Check the parameters of the display screenEnsure that the display screen parameters are clear, realistic, and accurate.
6. Check the communication interface and data acquisition systemEnsure the normal connection and data transmission between the instrument and the computer or other external devices.
7. Check the grounding conditionEnsure that the instrument is well grounded and the lightning protection grounding wire is not loose or corroded.

4、 Environmental Control and Storage

1. avoidharshenvironmentAvoid using dew point meters in environments with severe temperature and humidity fluctuations to prevent instrument performance from being affected by environmental factors. When storing dew point meters, it is also necessary to ensure that the storage environment is dry and the temperature is moderate, avoiding exposure to moistureharshStore under temperature and humidity conditions.
2. Use protective boxIt is best to store the dew point meter in a dedicated protective box to further protect the instrument from external environmental influences.

5、 Record and archive management

1. Maintenance RecordKeep records of equipment usage and maintenance, including usage time, problems encountered, and maintenance measures. This can promptly identify trending issues and effectively address them.
2. Archives ManagementEstablish a comprehensive instrument archive management system to archive and preserve records of instrument usage, maintenance, calibration, etc. for future reference and traceability.
