6. Auto power off.Specification:Range: 0-1.8mm, 0-71mils
Car mode resolution: 0.05mm/2mil
User mode resolution: 0.01mm/1mil
Accuracy: +/-0.1mm
Modes: Single & Continuous
Power supply: 2 x AAA 1.5V batteries (not included)
Dimensions: 62 x 30.5 x 105mm (2.44 x 1.20 x 4.13in)
Weight: 57.20g
Operation Temperature: 0~40℃ (+32~104℉)
Operation humidity range: 10~95%RH
Operation Instruction:
1. Turn on
Short press power button to turn on the instrument. After LCD full-screen display, model information will show on the screen (indicator Car appears under Car mode, no indicator appears under User mode), then follows measurement interface.
2. Select mode
Long press MODE buttonunder measurement interface to switch Car/User mode
3. Car mode
Car mode can be used without calibration, which can measure coating thickness ofthree substrate materials-iron, aluminum and zinc, suitable for measuring the coating thickness of cars.
4. User mode
User mode requires calibration before use, which can measure coating thickness ofsubstrate material for calibration.
5. Auto power off
The instrument will power off automatically in two mins of no measurement, or in five mins after measurement.
6. Measurement of coating thickness
1). Press power button in the air to turn on the instrument, after LCD full-screen display follows a BI sound, which means that measurement state begins. Every time of power on is regarded as single measurement.
2). Press the probe lightly on the coated metal substrate, the instrument will let out two sounds of BI-BI, with LCD showing the measured value of coating thickness.
3). Press MODE button to select measurement way. There are three measurement ways to choose from: single measurement, continuous measurement, difference value measurement.
4). Single measurement means one data each time. Continuous measurement means as long as probe does not leave suface of substrate, the instrument will keep measuring. Difference value measurement means the difference value between this time and last time of measurement.
5). Press UNIT button to choose unit. There are metric unit (mm) and imperial unit(mil) to choose from.
6). If you turn on the instrument on metal substrate, ERR (error) will show after LCD full-screen display, then the instrument will power off because of wrong start-up way.
Notice for users:
1. Since Car mode has built-in data, the user can no longer conduct calibration. Car mode can directly measurecoating thicknessof iron, aluminum, zinc substrate, suitable for measuring thecoating thickness of cars.
2. Under User mode, after calibrating metal substrate, user can only measure coating thickness of this metal’s surface, not other metals. For example, if you calibrate an iron substrate, you cannot measure coating thickness of aluminum substrate.
3. User mode calibration will not influence Car mode.
4. Car mode is default factory setting.
5. Default factory setting uses iron substrate to calibrate User model.
6. Calibrating under User model, diameter of substrate should be≥50mm, substrate thickness should be ≥0.5mm.
