Flashlight: It conveniently illuminates the measurement environment, making the operation more accurate and efficient. Backlight: Precise readings can still be made even in dim light. it ensures clarity and accuracy, freeing the measurement work from the constraint of light. Ture RMS - Can measure AC voltage of any waveform,unaffected by the waveform,making true RMS measurement more accurate. Overload protection - Built in intelligent anti burn chip and ceramic fuse,with overload protection to prevent accidental operation of the device,making it safer to use. Live Wire Detection Mode - This mode can accurately distinguish between the live wire and the neutral wire in a circuit. Manual mode: AC voltage,DC voltage,AC Current,DC Current,Capacitance,Resistance,Frequency,Diode,Continuity(On-off beep),Live wire check,Non-contact voltage. Auto mode: AC voltage,DC voltage,Resistance,Continuity(On-off beep) Data hold: One step to hold the data,ending the interference of the test pen. Auto power off: If no operation is done on the machine within 15 minutes, the machine will automatically shut down to protect the battery power. Low battery indication: When the battery is too low, the "Battery" icon on the screen will light up to remind you to replace the battery in time. Specifications:B:FY106B FY106B:VA LCD Screen VA LCD is a type of LCD. It has a high contrast ratio and can present deep black and bright white.
