Operating Specification
Use the DIP switch to set the CT Meter bar graph range,
and the current transformer (CT) ratio if used. The CT
ratio is shown as the target value. Use the software to set
other value CTs.

Intended Use: The APM has been specifically designed for engineers requiring an effective way to monitor and display
data. The APM accepts a range of electrical inputs (depending on the model) and displays the data on its integrated
multi-format display. The APM has been designed for installation into electrical cabinets or display panels. Output
models include two independent outputs that can be configured by the user to be either digital set-point outputs or
4-20mA monitor outputs.
