DW500UB-2V Linearity error Linearity error is defined as the deviation from a straight line. The max current and another trendline is calculated from 0 to negative max current. The difference between each measured point and the squares method of the measurement points from 0 to positive Measurement Trendline linear trend line is the linearity error. The linearity error ǫL can be expressed as (1), where Ireading is the measurement result and Ifitted Linearity error straight line is a linear regression trend line based on the least Figure 1: Linearity error definition Reading and full scale...

DW500UB-2V Isolation specifications according to IEC 61010-1 When using REINFORCED insulated wire, all wiring must be insulated for the highest voltage used. When using BASIC insulated or uninsulated wire, follow the specified voltages in the table below: Parameter Creepage distance Comparative tracking index (CTI) Continuous working voltage according to IEC 61010-1 with: Uninsulated wire: CAT III (dc and rms) BASIC insulated wire: Transient voltage according to IEC 61010-1 with: Uninsulated wire: CAT III BASIC insulated wire: Do not connect the transducer to signals or use for measurements...

When multiple primary turns are used or high primary currents are applied the temperature around the transducer will increase, please monitor to ensure that the maximum ratings are not exceeded. It is recommended to have minimum 1 mm2 per ampere in the primary bus bar. Transducer Connection - Control Cable Connect the control cable to the circular connector on the front of Mains Connection via C7 Cable Use the supplied mains cable to connect mains power to the control box. The control box is designed for using universal mains 100-240Vac, 50-60Hz. The product is designed as a Class II...

DW500UB-2V Status LED The Status LED is indicated with this symbol For a typical RG58 cable, the signal velocity is around v = 198 · . When the LED is ON (green light) it means that the cable to the transducer is connected, and the unit is ready for measurements. If the LED is OFF (no green light): • The cable from the transducer to the control box might not be • The current is out of the measurement range • Current have been applied to the busbar before powering the unit • An internal error has occurred Control Cable It is important that the 3m cable from the transducer must be connected...
