Extech EX623 True RMS Clamp Meter with IR Thermometer is a 400 Amp True RMS AC/DC Clamp Meter
The Extech EX623 is a heavy-duty multimeter featuring dual input thermocouple temperature measurement, non-contact IR temperature sensing, and non-contact voltage detection. It measures AC current up to 400A, DC current up to 400A, AC/DC voltage up to 600V, resistance, capacitance, frequency, duty cycle, and continuity.
| Maximum AC/DC Current Input | 400A DC/AC |
|---|---|
| Maximum Voltage Input | 600V DC/AC |
| Resistance/Capacitance/Frequency Max Input | 250V DC/AC |
| Temperature Input Type | Type K |
The meter supports a maximum input of 400A for both AC and DC current measurements.
Select ADC mode with no conductor in the jaw, then press and hold the MODE ZERO button until two beeps are heard.
You must remove power from the device under test before performing Diode, Resistance, or Continuity tests.
