The 773 is ideal for troubleshooting transmitters, valves, and programmable logic controllers (PLCs) found in process plants. It measures low level dc current and correlates process indication with a real physical value. And it measures up to 99.0 mA non-contact, including 10 to 50 mA signals in older control systems.
The 773 also sources and measures dc voltage, so it can be used to troubleshoot voltage input and output devices. You can detach the clamp section of the meter and use it as a remote jaw, connected to the main body by an extension cable to make it easier to take measurements in tight spaces. Plus, automatic power-off features save battery life so you can work longer without changing the batteries.
