The Fluke 789 Process Meter is a handheld, battery-operated tool designed for measuring electrical parameters and supplying steady or ramping current to test process instruments, similar to the 787 model. This instrument also features a built-in 24 V loop supply that enables it to reduce the need for taking a separate power supply when doing offline transmitter testing.
