EP105 timer counter

EP105 timer counter is a matching instrument designed for psychological instruments. It is used to count the time of the entire experiment and count the number of occurrences at the same time in the time. Therefore, it is widely used in psychological instruments, such as: Labyrinth, two-handed adjustment, two-armed adjustment, mirror painting instrument, stable movement, etc.

EP105 type timer counter adopts CMOS integrated circuit imported from abroad, and uses quartz crystal with stability up to 3.2768 MHz as the time base oscillator. After sub-frequency division, the timing reference frequency of 10mS is obtained, so there is a higher timing The precision is 100 times that of general electronic watches, so the EP105 chronograph counter meets the requirements of general experiments in psychology.

Timing range 0.00 to 9999.99 seconds Timing accuracy display error ± 1/100 second Counting range 0 to 999 times Weight 0.3 kg Power supply AC 220 ± 22 V Power consumption power 5 watt volume

1. Insert the lead plug from the psychological experiment instrument into the input socket of the machine (note that the plug should be in one-to-one correspondence with the socket before insertion, and must not be misaligned).

2. Turn on the power switch to display the "0000.00" timing display status. The user can also press the N / T button to display the "000" count display status. When the experiment starts, the timing starts. If the display shows the timing state, the user can see the number jump and the counter in the instrument enters the counting state.

3. When the experiment is over, the timer stops, the count is locked, and the buzzer sounds. The user can switch the display state by pressing the N / T button to obtain the experimental data.

4. If you want to run the experiment again, you can press the RET button, the instrument is reset, and you can start the next experiment.

1. START start terminal, active low

2. 5V 5MA output (for LED use)

3. 5V 50MA output

4. Count terminal, counting from low to high

5. STOP terminal, low level is effective

6. Ground

Note: The input impedance of the stop, start and count terminals is 47 kohm

1. The instrument should be used within a range of 220 ± 22 volts AC.

2. The voltage output and current of the instrument should be strictly controlled under the specified value (see the schematic diagram of the input socket).

3. When turning on the power of the instrument, especially when the power switch is slow, occasionally the instrument will automatically enter the working state. This is because the instrument has a very high sensitivity to start the timing in order to ensure the timing accuracy. At this time, the user can return to the original state simply by pressing the RET button.

4. When not in use, the instrument should be stored in a dry place.

5. It is strictly forbidden for users to disassemble, install or modify this instrument without permission.

Automatic Vacuum Forming Machines

Usually for Thin plastic (0.2-1.5mm) forming,Vacuum forming, commonly known as vacuuforming, is a simplified version of thermoforming.

whereby a sheet of plastic is heated to a forming temperature, stretched onto or into a single-surface mold, and held against the mold by applying vacuum between the mold surface and the sheet.
