1 Instrument Operation Guide

Please note: If the tablet is used for a long time without shutting down, please regularly close the background programs.

The steps to close the background program are as follows：

a.Click the box button in the bottom right corner to display the recently opened program software, as shown in the following figure;

b.Swipe the corresponding software to close the background history program.

1.1 Main Interface

Between on-site tests, the first step is to determine the measurement method to be used:

If using thermodynamic method, please arrange GPD1.5W Mining intrinsically safe wireless voltageForce sensorsGPD20W Mining intrinsically safe wireless pressure sensorGWB100WMining intrinsically safe wireless temperature sensorCDZ3 Motor electrical parameter tester（optional）；

press KJD3.7-A The power button on the right side of the mining intrinsically safe tablet computer,After waiting for the instrument to start, click on the 'Water Pump Wireless Multi parameter Tester' to enter the testing processThe main interface of the test software is shown in the following figure:

1.1 sensor

Click the 【 Sensor 】 button in the main interface to open the sensor interface,

On this interface, sensors and tablets can be automatically paired for communication, forming pairsThe post power indicator light is green, and communication failure is gray, as shown in the following figure:

The meanings of the buttons in the interface are introduced as follows:

Current frequency: Set and display the wireless frequency signal currently used by the tablet computerRoad number; The optional range of frequency channels is 1、2、3If you want to choose to use the newThe frequency channel number needs to be deselected as' Continuous Reading Battery 'before it can be inputtedEnter a new frequency number. It is generally not recommended to manually modify the frequency here.

Select: Select or deselect a sensor, and the selected sensor will beTest the interface for use.

power level%Display the remaining battery level of the sensor as a percentage.

Before arranging sensors on site, it is necessary to perform equipment pairing operations to confirm that all sensors to be used are working properly. The specific steps are as follows:

1Open the tablet to the main interface, and upon entering the interface, the instrument will select an unused wireless channel frequency;

2Enter the device pairing interface and check all the options to be usedbiography

Sensor, ensuring that 'continuous reading of battery level' is in the selected state; Turn on the power switches on all the sensors to be used one by one, and view the status indicator lights and battery percentage in the "Device Pairing" interface.

3If the status and battery display of all sensors used are normal, return to the main interface and open the data zero calibration interface.

4According to the data zeroing steps, calibrate the necessary sensors (inlet pressure, outlet pressure, and temperature difference)），After the calibration is completed, the power of the tablet and sensors can be turned off.

5Install the on-site sensors, and after all the sensors to be used are installed, turn on the switches of the tablet and sensors again, and follow the testing steps for testing.

When there is abnormal sensor communication on the testing site, such asHow to handle:

1If the status of a sensor is displayed in gray, it indicates that there is a problem with the sensor. Please turn on the switch of the sensor again and try again.

2、If the status of all sensors is displayed in gray, it indicates that there is a malfunction on the tablet or that the tablet and sensors are not on the same channel. Please reopen the software and try again.

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.
