1 Maintenance and Care

1. Measurement must be carried out under stable operation of the water pump.

2. The temperature sensing element is a platinum resistor, and a temperature measuring sleeve is used for temperature measurementThe material of the pipe is steel pipe or copper pipe, and oil should be injected inside the pipe to improve heat transfer or sealingSealing conditions.

3. The working temperature of the pressure probe is 70℃, when measuring pressure on site，Translate into EnglishThe pressure probe is installed on the joint with a three-way pressure pipe for measuring pressureWhen installing, you can first turn off the three-way valve or stop the water pump, install the probe, and then start it again）.

4. Temperature and pressure probe components are easily damaged. During the storage period of the instrument after testing, it should be noted that the probe and cable connections should not be pulled or folded with force. They should be handled gently and not collided or dropped to avoid damage or affecting the accuracy of the instrument testingDegree.

5. The instrument cannot be disassembled by itself, and internal components should not be replaced or adjusted arbitrarily,To avoid human damage or measurement errors.

6. Please keep the instrument and probe clean during and after use; makeDuring use, transportation, and storage, attention should be paid to shock and moisture prevention, and it should be placed in a well ventilated and dry placeDry, indoor environment without corrosive gases around.

2 Transportation and storage

1. The instrument power should be turned off during transportation and storage.

2. Do not store in high temperature places such as direct sunlight, carriages, or cabins.
