Diagnostics of the car body to assess its condition. For example: when buying a car, before repairing dents without paint (PDR), or scratch removal. Device care Please keep in mind that the device is a high precision measuring instrument. Avoid dropping the device and subjecting it to mechanical impact. The device is protected against moisture, but is not waterproof. It must not be used underwater or in heavy rain.
Cleaning the device To remove dust from the device case or the sensor, use a soft, dry cloth. Do not use cleaning agents containing organic solvents. Storage conditions Store the device in a warm and dry place away from direct sunlight. Do not leave the battery inside the device during long term storage. Do not leave the device near strong sources of magnetic fields, for example, near magnets, power supplies or electric motors.
substrate under the coating when measuring in automatic mode, without having to look at the display. Sensor To increase the accuracy of measurements and to enable measurements on convex and concave surfaces, the device uses a sensor constructed to stabilize the pressure on its sensitive tip against the surface, as well as a spherical form for its sensitive tip. The sensitive part of the sensor is made of high-strength heattreated steel, and the area of contact with the measured surface is less than 1 mm².
Before first use, or in case the device has not been used for an extended period, as well as to increase the measurement accuracy, you need to calibrate the device using one or two points of reference. Installing the battery Open the battery cover, shifting the cover with your thumb in the direction of the arrow. Insert the battery, taking note of the polarity. Close the battery cover until it clicks.
The device will begin to automatically test and calibrate the sensor. After 2-3 seconds, the display will show dashes, indicating that the device is ready to take measurements. IMPORTANT! When turning on the device, keep it away from metal objects and strong sources of magnetic fields! Turning off the device To turn off the device from any state, press and hold the button for 2 seconds. Display backlight The device has an integrated backlight for the display.
Operating modes The device has 5 operating modes: A, M, P, F(Fe), N(nFe). To switch between these modes, shortly press the button, which will switch modes in a loop. The current mode will be shown on the display. A - Auto: Quick measurement with automatic selection of measurement method. Dynamic resolution. Great for checking the car body. M - Manufacturing: Detailed and precise measurements with high resolution across the entire range. Automatic selection of measurement method.
N(nFe) - Eddy current method: Quick, continuous measurement (4 measurements per second) of coating thickness on an aluminum alloy substrate, using eddy current. For accurate measurements, it is recommended to complete the two-point calibration before measuring. Units of measurement For user convenience, the device can display the results of measurement in several units of measurement: millimeters, mils, and micrometers.
Taking measurements in A, M, P modes (automatic modes): Firmly place the device sensor flat against the surface to be measured. Do not move the device during measurement (until a sound signal is emitted), otherwise the measurement may be inaccurate. Once the device detects that the sensor is on the surface in a fixed position, you will hear a sound signal indicating the completion of measurement. Move the device away from the measured surface.
These modes are useful when it is difficult to hold the device in a fixed position. For example, when measuring on pipes, convex and concave surfaces. Calibration For accurate thickness measurements, the device needs to be calibrated. The device retains the calibration information and in most cases you don't need to calibrate it again before every use. Be sure to check and complete the calibration the first time you use the device, or if you have not used it for a long time.
Keep a clean environment during calibration, as the slightest bit of dust stuck between plastic and metal base plates may distort the result by 5-10 µm. Zero deviation calibration (one-point calibration) When to calibrate: 1. When measuring on a metal substrate without a coating, the device will show a result greater or less than zero (depending on the properties of the metal substrate). After calibration, the device will display zero. 2. In cases where you need to measure deviation from a sample.
Verify the result by repeating the measurement. Removing calibrations This function will completely remove zero deviation and two-point calibrations for all modes. This function will restore the device's functionality in case of incorrect calibration, but for accurate measurements it needs to be calibrated again. To remove calibrations, when the display shows dashes , press and hold the button for 3 seconds. The display will show "-CL-" and a sound signal will be emitted.
Two-point calibration When to calibrate: - Before first use; - If the device has not been used for an extended period; - Before each measurement for maximum accuracy. Two-point calibration procedure: To enter calibration mode, press and hold the button for 2 seconds until the display shows "F-0". This indicates the zero point calibration. Take a measurement on a metal substrate without a coating, for which the device will be calibrated. If necessary, repeat the measurement.
result is being displayed, shortly press the or buttons to adjust the displayed thickness of the measured coating, and shortly press the button to save the calibration. The display will show "8888", indicating that the calibration has been successfully saved. Verify that the calibration is correct by repeating the measurement of the metal substrate with and without the sample coating. If unsuccessful, repeat the calibration.
F-4 (point 4) - Plate with a thickness of 1900-2500µm (75-98 mils). F-5 (point 5) - Plate with a thickness of 2600-3500µm (102-137 mils). Entering the calibration mode: Turn off the device, then press and hold the button to enter calibration mode for a ferrous metal substrate (magnetic induction method) or the button to enter calibration mode for a nonferrous metal substrate (eddy current method), until the display shows "FCAL" or "ACAL" respectively.
The display will show "F-1" - the next point of calibration, and the device will show the recommended thickness of calibration plate for the current point of calibration. Take a measurement of the metal base together with the calibration plate. If necessary, repeat the measurement. Use the and buttons to calibrate the displayed thickness of the measured calibration plate, and shortly press the button to proceed to the next point. Repeat the procedure for each point of calibration.
Please note, if the calibration is done incorrectly on one of the metal base types, the device will be unable to automatically detect the type of substrate material and choose the suitable measurement method. The new device's six-point calibration is identical to the factory calibration. The device is calibrated at the factory using steel (magnetic induction method of measurement) and aluminum (eddy current measurement method) substrates.
