Electric digital display low temperature compliance tester

Introduction:

This instrument is designed and manufactured according to GB/T328.14-2007. The electric digital display low temperature compliance tester is used to determine the minimum temperature at which the bitumen waterproofing membrane is bent without bending under the specified conditions. It consists of a low temperature compliance test mechanical part and a control instrument part. Work in freezing fluid or air. It has the advantages of convenient use and high intelligence. It is an ideal new standard product for testing units, coil production units, universities and colleges. The series low temperature compliance tester adopts a number of international advanced technologies. The input adopts digital calibration and self-calibration technology. The measurement and control are accurate and stable, and the measurement error caused by temperature drift is eliminated. The instrument adopts multiple protection and isolation design, which has strong anti-interference performance and high reliability.

Installation and commissioning

1. Put the sink into the low temperature box and add the freezing liquid. Any mixture of frozen liquids:

- propylene glycol / aqueous solution (volume ratio 1:1) as low as -25 ° C, or

- an ethanol/water mixture below -20 ° C (2:1 by volume).

The liquid level is 100mm, and after the test piece has reached the specified temperature, it will remain at this temperature for 1h±5min.

2. Connect the host and controller lines, turn on the power supply 220V, and have reliable grounding. Turn on the power switch and adjust the bending axis position through the rising, falling, and stopping buttons on the control panel. Let the test piece be placed at the lowest end. The size of the test piece is (150±1) mm×(25±1)mm. Before starting all the tests, the distance between the two cylinders (see Figure 1) should be according to the test piece. Thickness adjustment, ie the diameter of the bending axis + 2 mm + the thickness of the test piece. The device was then placed in the cooled liquid and the upper end of the cylinder was about 10 mm below the surface of the frozen liquid, with the bending axis in the lower position.

It can be 20mm, 30mm, 50mm depending on the product.

temperature setting

: Click the [Temperature Settings] button, the system will enter the temperature setting process (the temperature setting range is:

-50.0-+99.9

°C), at this time, the temperature display area digital tube will be at 2Hz frequency

Flashing

Display the last temperature setting result, click the [Add] button, the temperature setting value will rise at 0.1 °C resolution; press and hold the [Add] button, the temperature setting value will rise continuously; click the [Decrease] button The temperature set value will be reduced by 0.1 °C resolution; press and hold the [minus] button, the temperature set value will decrease continuously. After adjusting the temperature to the value you need, click the [OK] button and the temperature setting is completed.

4, temperature calibration

: Click the [Temperature Calibration] button and the system will enter the temperature calibration process (the temperature calibration range is:

-50.0-+99.9

°C),

At this time, the temperature display area digital tube will be at 4Hz frequency

Flashing

Display the actual value of the uncalibrated collected temperature, click the [plus] button, the temperature value will rise at a resolution of 0.1 °C; press and hold the [plus] button, the temperature value will continue to rise; click the [minus] button, the temperature The value will be reduced by 0.1 ° C resolution; press and hold the [minus] button, the temperature value will continue to decrease. After adjusting the temperature to the standard value you need, click the [OK] button and the temperature calibration is completed.

5, time setting

: Click the [Time Setting] button, the system will enter the sample test duration setting process (the sample test duration setting range is:

1-9999

minute

),

At this time, the time display area digital tube will be at 2Hz frequency

Flashing

Display the last time setting value, click the [plus] button, the number of minutes will increase by 1 minute resolution; press and hold the [plus] button, the number of minutes will continue to rise; click the [minus] button, the number of minutes will Reduced by 1 minute resolution; press and hold the [minus] button, the number of minutes will decrease continuously. will

Time setting

After adjusting to the setting value you need, click the [OK] button to complete the time setting operation.

6, lift time setting

: When the sample test is finished, the controller will automatically raise the test piece. The default process time of the rising process is 10S, then the lifting process will be automatically stopped. To change this setting, click the [lift time] button. The system will enter the lifting time setting process (the lifting time setting range is:
