Page 6: General
AKM 345 Gen2 Instruction Manual (Rev No. ECN-27992) General The AKM345 next generation, GEN2 for short, is a world class, robust CE approved fully weather proofed temperature indicator, used globally for electricity transformers. It is designed and manufactured for long and trouble free outdoor operation under all conditions. To secure maintenance-free operation, the installation on the transformer must be made with care. -
Page 7: Optional) Adjustable Switch Differential Setting Instructions
AKM 345 Gen2 Instruction Manual (Rev No. ECN-27992) Tighten the screw in this position. • • Check that contact is obtained by slowly turning the shaft of the drum so that the • pointer of the temperature gauge moves towards higher values on the scale. The shaft of the drum must not be turned in the other direction since the calibration of the instrument may change. -
