What is a Digital Timer?

When the digital timer is turned on, especially when the power switch is turned on slowly, occasionally the instrument will automatically enter the working state. This is because in order to ensure the accuracy of the timing, the timing sensitivity of the instrument is extremely high, and it is susceptible to the electrical contact of the switch. As a result, the user can return to the original state by pressing the RET key at this time.

Digital timer

From psychology

Timing range 0.00 9999.99 seconds

Display error ± 1/100 seconds Count range 0 999 times

Weight 0.3 kg AC 220 ± 22 V

Counting delay 100 milliseconds

Power Consumption: 5 Watts

1. GND (ground)-The ground of the input signal.

2. START (starting end)-timing starts when the level changes negatively.

3. STOP (stop)-stop counting when the level changes negatively.

Note: the input impedance of the signal input is 47 kohms, and the maximum input voltage is 5 volts

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 diagram of the input socket).

3.

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

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