The Extech EX570 True RMS Autoranging Multimeter is a high-precision digital multimeter that measures AC/DC voltage, AC/DC current, resistance, capacitance, frequency, duty cycle, diode test, continuity, and thermocouple temperature and infrared temperature.
This user guide explains how to safely operate the Extech EX570 True RMS autoranging multimeter, including measurements for voltage, current, resistance, capacitance, frequency, and temperature. It includes safety warnings, control descriptions, and step-by-step instructions for each measurement type. The meter features a waterproof, rugged design for heavy-duty use and includes an IR thermometer for non-contact temperature measurements.
The guide emphasizes safety precautions, such as disconnecting power before testing, avoiding high-voltage measurements without caution, and proper handling of test leads and batteries. It also details the meter’s input protection limits and overvoltage categories for safe operation.
The maximum input voltage is 1000 VDC/AC rms.
The maximum current is 10A AC/DC, with a 20A limit for 30 seconds max every 15 minutes.
