Current transformer Current transformers with either 1A or 5A sec- Primary (5.00kA = 5000A) ondary can be connected to the UMG96L. A transformer ratio of 5A/5A is preset by the manufacturer. In programming mode the cur- rent transformer setting is marked by the sym- bol „CT“.
Voltage transformer Primary voltage The phase to phase voltage (L-L) is indicated on display of the UMG 96L as secondary and primary voltage. The transformer ratio is calcu- lated from the programmed primary and sec- ondary voltage. In programming mode, the vol- tage transformer settings are marked by the symbol „VT“.

Measured value selection All measured values stated in table 1 (see page 16 and 17) can either be displayed via keep 1 and 2 measured value selection or automati- cally measured value rotation. All measured values for the measured value selection are preset by the manufakturer.
Delete minimum and maximum values In programming mode, „Deletion of minimum and maximum values“ is marked by arrows up- wards and downwards. All minimum and maxi- mum values will be deleted simultaneously in menu „Deletion of minimum and maximum val- ues“.
Working hours counter The working hours counter detects the time, in which the UMG96L measures and indicates data. The time is measured with a resolution of 15 minutes and is indicated in hours. The work- ing hours counter cannot be deleted. Display example: The UMG96L indicates 40201 working hours.
Software Release The internal software of the UMG96L will be improved and extended continuously. The soft- ware update is registered in the device by a specific number the so called software release. The software release cannot be changed by the user.

These specifications presuppose a yearly calibration and a warm up time of 10 minutes. Used abbreviations: = of measuring range = of measured value Measuring range with scale factor = 1, (Current tranformer = 5/5A, 1/1A) ) In the range of -10..18°C and 28..55°C, an additional error of +-0,5‰ of measured value has to be considered per K.
