Extech MO290 & MO295 Moisture Meters
An informational video about the new MO290 and MO295 Pin/Pinless Multifunction Moisture Meters from Extech Instruments.
Clamp meter inrush currents. EX623.
Inrush can get extremely high. What is the safe inrush current for this 400 amp meter? With the time involved considered? I work regularly with 50 HP and higher @ 600V where 1HP=1A. Inrush
typically can be 300% and higher.

Bradley, because this is a clamp meter, the EX623 will not be damaged by current values higher than 400 A. It will just give an out of range indication. The clamp doesn’t make a physical connection to the circuit like a multimeter in current mode would.

Thank you. The EX623 is the favourite of my Extech family and I didn't want to hurt Him. He's worth his weight in gold around VFD's. His name is Clyde the Clamp. My EX570 is Morty Multi.
