Instructions:
Start counting: counting terminal input contact signal, the counter starts counting.
Temporary count: Press the Count / Pause button (PAUSE), suspended from counting; then click the Count / Pause button (PAUSE), resumes its count.
Panel clears: simply press the Delete key (RESET).
External clear: Clearing the terminal contacts connected directly to an external cleared.
Counter ultra-low power, 24-hour use, and AA batteries can be used more than six months, you can use the high-performance battery 5 year and a half to two years.
The magnetic sensor and the magnet switch according to the actual work flexibly mounted on the appropriate location of the device, allowing the device to be counted to complete a work process, the magnet is close to leaving the magnetic sensor switch once again, to be used to complete a count ; Note: only sensor magnet, other things can not be sensed.
In operation, the device allows the magnet to follow the movement of magnetic proximity sensor switch 0.5-1 cm distance, and then let the magnets away from magnetic sensing switch distance of more than 3-5 cm above the counter +1 count, repeat the above process, the counter will be accumulated count: 0,1,2,3,4,5,6 ...... (Note: when you leave the magnet count); installation, please adjust the position and distance of good magnet and sensor switch.
Precautions:
1. the counter clear signal input signal and switch or circuit should be as close to the terminals of the counter so that the signal lines as short as possible.
2. Avoid the other, such as: high voltage wires or power wires, etc. with the tube or stranded traces to avoid unnecessary interference, if necessary, use shielded cable, shield connected to the terminals + count on.
3. count signal and the clear signal only contact signal input, can not enter the other electrical signal.
4. The contact input should be reliable, so as not to cause false contacts bounce count, error is cleared.
5. When the LCD display fuzzy, replace the battery. When a long time, remove the batteries to prevent battery leakage and damage deterioration counter, remove the battery, and press the Count / Pause button (PAUSE), so that the screen display disappears, to close the counter internal auxiliary battery.
Note:
Be sure to install the battery after use! !
Unscrew the two screws securing the housing, gently separate the back cover (be careful not to pull off the signal line), into a 5 batteries (sold separately), close the cover, screw the two housing screws.
