Pressure test machine operation

Pressure Test Machine Operation

One, specimen of operation,

1, According to the requirements of experiment on specimen, rotation of the screw ,the upper pressing plate does not contact the specimen is limited, open the pressure machine, after rising cylinder, press [reset清零] key to clear tare.

2, The instrument was energized, or in the status of measurement press [parameter 参数] button to start the test .

Instrument display:

P0001

S----2

P0001 means the specimen number is 0001 ( 1 is flashing)

S----2 refers to the test section of specimen code is 2 ( 2 is flashing)

Section code 1, 2, 3, 4, 5, 6, 7, 8, respectively:

1 -- 100 x 100 x 100mm cubes

2 -- 150 x 150 x 150mm cubes

3 -- 200 x 200 x 200mm cubes

Specimen 4 -- with arbitrary cross section

5 -- 150 x 150 x 150mm bending specimen

6 -- 100 x 100 x 100mm bending specimen

7 -- 40 x 40 x 160mm bending specimen

8 -- 70.7 x 70.7 x 70.7mm cubes

According to the corresponding number keys, enter a 4 digit number, ;if need enter "0108", then input for: "P0108" then press [confirmed确认] and then enter the cross section of the specimen, input 1 (or 2, 3, 4, 5, 6, 7, 8), if the user input into 4 sections when the actual input section, should be the value (mm2), such as the cross-section of 100 x 100mm should enter "10000" press [confirmed 确认] key then start the test. In the test without force, display serial and number in meter speed box, as shown in "108-1", said the current specimen serial is 0108, number is 1.

Open the oil valve loading, force value exceeds 2KN instrument began to show force

value, according to the requirement of rate control oil supply valve loading, until the specimen fracture, open the oil return valve, instrument automatically record the peak pressure, and saved to the memory, to join this serial specimens in the second test pieces, press [reset清零] button remove the last test force value, close the oil return valve, control oil supply valve loading until fracture of specimen, open the oil return valve, instrument automatically record the peak pressure, and saved to the memory test, third blocks test after press [reset清零] button. after the end of this specimen, if the user sets the automatic printing, the instrument will automatically print out the test results (such as user choose cross selection is 7, to carry out sixth pieces of test,after test of this specimen, the instrument will automatically print out the results, if not done a group test, want to end the shuffle test, to press [End结束] key, at the same time discrimination data is valid, such as effective, calculate the average, the next set of tests automatically into the same section finished printing equipment.

Two, query operation

Press the [query查询] button on the query measurement conditions, instrument display "P----", enter the group number, such as "P0020", press the [confirmed 确认] button to confirm, instrument display the failure force of first piece of specimen,then press the [confirmed 确认] button to confirm, instrument display the first block specimen breaking strength, press [confirmed 确认]button, other specimens test value and strength can view , according to [Cancel取消] button to exit.

Three, a printing operation

Press the [Print打印] button on the measurement conditions, instrument display "P0000-0000", enter the group number range, press [confirm确认] button.

Four, metrological verification operation

According to the provisions of the metrology law, dynamometer test once a year, for legal metrology departments designated by the local and technical supervision
