This manual introduces the functions and features of the Extech 430 True RMS Autoranging Multimeter
The Extech 430 is a True RMS Autoranging Multimeter designed to measure AC/DC Voltage, AC/DC Current, Resistance, Capacitance, Frequency, Duty Cycle, Diode Test, Continuity, and Thermocouple Temperature. The device features a 4000 count LCD display and includes functions such as Relative, Hold, and Backlight.
| Display | 4000 count LCD display |
|---|---|
| Overvoltage Category | Category III |
| Max DC Voltage | 1000V DC |
| Max AC Voltage | 750V AC |
| Max DC Current | 20A |
| Max AC Current | 20A |
| Max Resistance | 250Vrms for 15sec max |
It measures AC/DC Voltage, AC/DC Current, Resistance, Capacitance, Frequency, Duty Cycle, Diode Test, and Continuity plus Thermocouple Temperature.
Do not make current measurements on the 20A scale for longer than 30 seconds.
The value exceeds the range you have selected, and you should change to a higher range.
