1、 Daily cleaning (after each use/once a week)

Wipe the body shell with a dry soft cloth to remove dust and oil stains, and avoid liquid infiltration into the interface

Dip a cotton swab in a small amount of anhydrous ethanol to clean the signal input/output interface and power interface to prevent oxidation and poor contact

2、 Precautions for use environment

Place in a dry and ventilated environment, avoiding humidity (relative humidity ≤ 70%) and high temperature (temperature range 15-30 ℃)

Stay away from strong magnetic and electric fields (such as large transformers and welding machines) to reduce interference

Avoid direct sunlight to prevent body aging and internal component performance drift

3、 Key component maintenance

Probe/Sensor: Regularly check whether the cable is damaged, whether the connector is loose, and replace it in a timely manner if it is damaged

Power adapter: Use the original adapter to avoid unstable voltage and damage to the equipment. Disconnect the power when not in use for a long time

Fan (if any): Clean the dust on the fan blades every 3 months, and promptly inspect and repair any abnormal speed or noise

4、 Operation and storage specifications

Before starting up, confirm that the power supply voltage matches. When shutting down, turn off the device switch first, and then unplug the power plug

Do not disassemble the body at will. If maintenance is required, please contact a professional

Long term idle (over 1 month): Start up and run for 30 minutes every month to maintain the activity of internal components, and store with a dust cover

5、 Simple fault prediction

iflock-in amplifierIf the signal is unstable, first check the cleanliness of the interface and cable connection, and then investigate environmental interference

The device cannot be turned on. Please prioritize checking the power adapter and socket to eliminate any power supply issues

When the numerical drift is severe, calibrate the equipment first (operate according to the instructions), and if it is still abnormal, contact after-sales service
