Model# DU-40
AC Voltage Digital Panel Meter
The DU40 & DU40-AC are low cost AC voltage meters. The DU40 is designed to measure power line voltage up to 700.0Vac with 0.1Vac resolution. Limited Availability.
- 4 digit red LED factory calibrated for 700Vac
- Display: Ā 0.56ā³ high efficiency LED display HOLD and TEST function
- Decimals:Ā Ā User programmable to four positions.
- Overload Indication: When input exceeds the full scale on any range being used, all digits flash at the A/D conversion rate.
- Warm Up Time: One minute to specified accuracy
- Input Configuration: Inputs resistively isolated to 1400V from internal ground of meter by 1.94 M O so that phase to phase measurements can be safely made.
