The Define Instruments LD-UAC panel meter can be used simply as a process indicator; its large display can be easily read from a distance. With the addition of relay outputs it can function as an alarm or on/off controller. An optional isolated analog output is also available for retransmission of the signal to another unit.

This unit is designed for ease of use, with screen prompts that guide you throughout the setup process. It uses a simple key-in calibration procedure eliminating the need for an input signal during setup. You can configure up to 4 setpoints, depending on the number of relays you select. Your settings remain secure with PIN protection; the input calibration and setpoint functions have independent codes so you can give access to one and not the other.

The LD-UAC uses input signal averaging to reduce noise and ensure stable measurements. If the change in input exceeds the averaging window value it will not average, ensuring fast response when there are large differences between readings.
