To fully understand its features and operation, we recommend reading this manual carefully before use. Safety Instructions (Must Read) 1， Before using DM40, please check carefully if the shell has cracks or defects, and ensure the measurement ports and accessories are normal. 2， DM40 integrates a rechargeable battery. For safety and measurement stability, please do not measure while charging. Low battery reminders may affect accuracy. Please charge promptly. 3， Please select the correct measurement port, range, and scale to avoid damaging the instrument or causing personal injury！ 4， Hold the probe at the protected position. Do not hold the metal part for measurement！ 5， Do not disassemble the case at will or measure while the case is open. 6， Do not use in environments with flammable or explosive gases/materials or in damp conditions. 7， For voltage measurement, when used for DCDC or high voltage above 36V measurement, it is recommended to use AUTO+ mode to skip the mV range (to avoid mismeasurement, sparking, and protection) and start measurement from the V range. 8， To use the Bluetooth function, please go to Settings > Other Settings, turn on the Bluetooth, return to Multimeter interface，and then connect via the APP(atk-xtool). 1，Product Introduction The DM40 digital multimeter is the first high-performance 3-in-1 multimeter launched by Guangzhou Xingyi …
