Tearing Tester Operation Process

NOTICE: The calibration of the instrument is completed before shipment. Do not alter the parameters of calibration, or this alteration may lead to incorrect test results. However, it is helpful for the operator to understand the calibration process.

• Enter the calibration interface from the main menu.
• The password for entering calibration is “888888”

Torque Calibration

Note: The torque data values are factory data, please do not modify!!

Friction Angle Calibration

1. After selecting the corresponding range through   (for example, A Range), press the   key, and input the password 11111 to enter the zero angle calibration interface.
2. Follow the prompts and press the   key to confirm.
3. Push the pendulum back to the starting position (by pressing the   key to lock the pendulum.)
4. Press the   key without holding any sample. The pendulum is automatically released in 1 second, the swing angle is measured, press   key to save the data.

NOTE:

• The same range can be calibrated multiple times until the ideal value is obtained. That is the corresponding range.
• Checking after angle calibration: Without loading the sample, press the   key to release the pendulum. The force is closer to 0, the result is better.

NOTE:

• The friction angle calibration is the horizontal position calibration of the instrument moving to different places! ! (The level bubble is roughly horizontal, the instrument does not know, so the horizontal position should be calibrated. )

• The reference angle of A range: 136.5 ~ 138 degrees and  B range 138 ~ 139.5. The calibration angle of both ranges can’t be ≥140 °)

Weight Calibration

NOTE: This is factory setting function, and is used to adjust the instrument.

Please contact the manufacturer first for advice.

1. Press the key to enter weight calibration interface.
2. Install the standard block, enter the weight of the standard block and press the key to enter
3. Push the pendulum back to the starting position (by pressing the key to lock the pendulum.)
4. Without holding any sample, press the key to release the pendulum.
5. Compare the measured value F and the theoretical value F ‘of energy consumption. It’s suggested the test result do not exceed 1% of the displayed value.
