2.安全上の注意

2.1 電気安全

Before connecting the power cord, verify that the supply voltage is AC 220 V ± 10% and the frequency is 50 Hz or 60 Hz;

You must use a three-prong outlet with a protective ground, with a protective ground resistance of ≤4 Ω. Under no circumstances should you cut or disconnect the protective ground wire, as doing so poses a risk of electric shock.

2.2 環境安全

Do not use in environments with flammable or explosive substances, strong electromagnetic interference, high temperatures and humidity, or excessive dust levels;

Operating Environment: Temperature 5°C to 35°C, relative humidity ≤ 65% RH.

2.3 操作手順

Improper operation can easily result in personal injury, equipment damage, and distorted test data; operators must thoroughly read this manual and strictly follow the procedures;

Remove jewelry before performing the procedure, tie back long hair, and do not wear loose-fitting clothing;

During the test, take precautions to prevent test specimen fragments from flying and causing injury;

During the test, do not extend your hands or tools into the fixture’s travel range to prevent crush injuries or accidents;

Operators must not leave their posts without authorization while the equipment is in operation; in the event of an abnormality, immediately shut off the power supply;

Do not perform tests that exceed the load capacity or stroke limit, and do not use damaged or non-standard fixtures.

5. Compression Test Procedure

5.1 Sample Preparation and Placement

Select a specimen of an electrical enclosure that is free of initial cracks, plastic deformation, and in perfect condition. Based on the specimen dimensions and in accordance with Section 4.1, use the up/down keys to adjust the platen to a position slightly higher than the specimen’s height, and place the specimen in the specimen mounting position as described in Chapter 3.

5.2 テストパラメータ設定

Set the compression force and duration in accordance with Section 4.3 and the relevant provisions of the standards.

Clause 15.3 of GB/T 17466.1-2019 (IEC 60670-1:2021 Clause 15.2) requires a force of 500 N applied for 1 minute; GB/T 17466.1-2019, Clause 15.5 (IEC 60670-1:2021, Clause 15.5) requires a force of 50 N/cm² (not exceeding 1000 N) to be applied through 9 mm thick plywood, with a duration of 1 minute.

5.3 Starting the Compression Test

数	お願い
①	Click the “Start Test” button to begin the test
②	Move the press block slowly toward the specimen and apply pressure.
③	When the actual pressure reaches the set value, the timer starts.
④	Once the force application time reaches the set duration, the test stops automatically and the load block returns to its original position.

Note: If the actual pressure does not reach the set value, or if the specimen breaks during the compression process, you may click “Stop Test” to manually terminate the test.

5.4 テスト結果の解釈

After the test is completed, the mounting box and housing must not exhibit any deformation or damage that would affect continued use; if this is the case, the test is considered passed.

6. 機器の日常的なメンテナンスと手入れ

6.1。XNUMX日常のメンテナンス

After each test, clean up any dust or debris from the specimen mounting area to keep the work surface clean and free of debris; wipe down the equipment surface to keep it clean; verify that the clamping block is secure and that the limit stops are not misaligned; apply specialized lubricant to the drive screw to ensure smooth operation.

6.2 Storage Specifications

6.2.1 保管環境の要件

温度：5℃～35℃、相対湿度：65%RH以下、乾燥した、埃のない、腐食性ガスのない環境。

6.2.2 長期保管業務

電源を切り、すべてのケーブルを抜いてください。機器を清掃し、防塵フィルムで包んでください。部品の湿気による損傷を防ぐため、毎月30分間電源を入れてください。

6.3 校正間隔の要件

To ensure the measurement accuracy and operational reliability of the equipment, it is recommended that it be sent periodically to a qualified third-party metrology laboratory for calibration. The recommended calibration interval is 12 months. The specific calibration interval may be determined by the user based on frequency of use, environmental conditions, and quality system requirements.
