Page 3: Brief Description
Brief description 1. Brief description With the digital indicator IAKV-2VR4C standard signals DC 0/4 … 20 mA or DC 0 … 5/10 V can be measured. The 4-digit display shows the measurements or the scaled value of the measurement. During programming the display is used to indicate the set values and the user prompts. -

Programming permanently in the unit. It means that a pre-adjusted transmitter can be operated directly with the indicator without any need to previously connect the signal to be measured to the indicator. The indicator can be scaled freely according to the physical dimension to be measured. 6.2.2. -
Page 15: Device Parameter
Programming 7. Device parameter The IAKV-2VR4C has a number of unit parameters with which the function of the indicator can be adjusted to the relevant measuring tasks. Because of the large number of these settings and the limited possibility of displaying them on the 7-segment display, the parameters have been given consecutive numbers. -
