Multimeter

• Solid-state relays for long life and low maintenance (100 times longer life than

mechanical relays)

• Higher scanning speeds of up to 500 channels per second

• Automatic CJC with no extra accessories required for thermocouple measurements

• Removable screw terminals offer simple, quick connections

• 20 channels for general purpose measurements

• Configurable as two independent banks of multiplexers
