Model# DU-40ACI5
AC Current Digital Panel Meter
The DU40-ACI5 is a low cost AC current meter. It has a built-in internal shunt that allows direct connection to a 5A CT (current transformer) without adding any other external features.
Calibration Procedure
- Apply an input of 0Aac to the meter by shorting the inputs.
- Adjust the Zero Offset Pot until the meter reads 0000.
- Connect the secondary of the current transformer (CT) to the meter
inputs, and apply the full scale current. (5Amps) - Adjust the Span Pot until the meter displays the required reading.
(Primary ratio of CT) - Place Decimal Point Jumper in proper position for CT Ratio.
- The DU40-ACI5 is now calibrated and ready for use.
