This manual introduces the use of Extech EX530 True RMS Autoranging Multimeter. The multimeter can measure AC/DC voltage, AC/DC current, resistance, capacitance, frequency (electrical & electronic), duty cycle, diode test, and continuity plus thermocouple temperature. The manual also introduces the safe use and maintenance methods of the multimeter.
The Extech EX530 is a True RMS Autoranging Multimeter designed for heavy-duty use with a waterproof, rugged design. It measures AC/DC Voltage, AC/DC Current, Resistance, Capacitance, Frequency, Duty Cycle, Diode Test, Continuity, and Thermocouple Temperature. The device features a 40,000 count LCD and includes buttons for functions such as PEAK, HOLD, MAX/MIN, and REL.
| Display Resolution | 40,000 count LCD |
|---|---|
| Max DC/AC Voltage | 1000VDC/AC rms |
| Max mA Current | 500mA |
| Max 10A Current | 20A for 30 seconds max every 15 minutes |
Use great care when making measurements if the voltages are greater than 25VAC rms or 35VDC, as these are considered a shock hazard.
Do not make 20A current measurements for longer than 30 seconds, as exceeding this time may cause damage to the meter and/or test leads.
If 'OL' appears, the value exceeds the selected range, and the user should change to a higher range.
