STORE: Maximum,minimum,and lastest values
DETECTION DISTANCE: 50 To 500MM
TIME BASE: 6MHz crystal oscillation
CIRCUIT: Large scale integrated circuits,high integration microcontroller
POWER CONSUMPTION: Approximately 40mA (operating hours)
OPERATING TEMPERATURE: 0°~50°C (32~122°F)

INTORUCTION TO USE:
1. Paste the reflective paper on the object to be tested.
2. Install the battery and press the “TEST” key to align the visible light with the installed reflective paper.
3. When the reading is stable,release the “TEST” button.At this time,there is no display value on the liquid crystal.But the maximum,minimum,and latest values (the last measured value) are automatically stored in memory.
4. Press the “MEM” key to display the maximum,minimum,and latest values in the loop.

OTHER THINGS TO NOTE REFLECTIVE:
Cut and tear off approximately 12MM square reflective appear and paste it onto any of the rotating shafts.Note that the non-reflective are should always be larger than the reflective area.
If the shaft is also reflective,apply black tape or black paint.Keep the surface of the shaft clean and smooth beforem pasting the reflective paper.

LOW SPEED MEASUREMENT:
When measuring low rotational speed,the reflective paper can be drawn onto the axis of the rotation on average and the display value divided by the number of sheets of reflactive paper is the correct rotational speed.When storing for a long time,remove the battery to prevent leakage.

STORE:
When the TEST key is released,the crystal is not displayed,but the maximum,minimum,and latest values are automatically stored in memory,and the stored values can be displayed on the LCD screen by pressing the MEM key.
