automatic oil acidity tester

I. Overview

HZCS-3 transformer oil acid tester is a fully automatic measuring instrument which adopts the extraction method to accurately detect the insulating oil acid value. This instrument can improve the working efficiency and test accuracy, and at the same time ensure the safety of the body by reducing the operator's contact with the samples and reagents.

The instrument will automatically search the samples, inject the extraction, make a blank titration, do an experiment, clean off, display printing results and other operations as long as the operator put the sample cups in the sample cup holes and inject the extraction in the cup. Once started, 1 to 3 samples can be measured, which is convenient and high efficiency.Because of the preparation of the standard acid for instrument calibration and calibration procedure, the clients can calibrate the instrument and the neutralizing liquid at any time so that the instrument can overcome the defect of changes in concentration of neutralizing liquid during use. At the same time, during the test the instrument will automatically deduct the background value of the extract so that the instrument can ignore the influence from the change of background value on the extraction. All these design make the result more accurate and reliable.

II. Maintenance

1. Replace the reagent

1) Replace a bottle of anhydrous ethanol when it run out ;

2) Configure a bottle of extraction when it run out and inject it into the cell;

3) Configure a bottle of neutralization when it run out and take out the bottle labeled with neutralization, inject the neutralization into the bottle labeled with neutralization and put it back. In this situation the instrument need re-calibration.

2. Replace the peristaltic pump tube

Open the upper cover of the instrument and turn the handle of the peristaltic pump to the right. Replace the old pump tubing with new pump tubing, then turn the handle of the peristaltic pump to the old position.

3. Replace the printer paper

Open the button shown on the picture above, and put in a new printer paper and close the cover of printer.

If there is no word, check whether the printing paper is reversed。

Shut down the power and press the “LF” button continuously, at the same time turn on the power, after 5s release the “LF” button and the printer enters the setup step, adjust the printer following the prompts。

In the open state, press the “SEL” button at a long time, the printer will self-tested print the font.

III. Operation Notice

1.The peristaltic pump hose is easy to wear. Please check whether the hose is damaged or adhesion carefully to reduce the impact on the instrument。If there is any abnormal, replace the hose. After the instrument finished, please release the squeeze arm of the peristaltic pump to prevent the peristaltic pump hose from being damaged by the arm.

2. It is recommended to re-calibrate with standard acid if the instrument is not used for more than three months.

3. When preparing the extract, the container must be dry and cannot have water. The extract is sealed and stored.

4. When the test is continuous, it is allowed that the cup cannot be cleaned. If not, the cup must be cleaned and the sample cups should be completely dry before use.

5. After the test must be cleaned off.
