Setting Zero Offset on mV-485 Adapter

    For many sensors with voltageĀ outputs (e.g. 0-5 VDC), an output of 0 mV equates to a reference value of 0. However, some sensors, such as Turner Designs Cyclops-7 fluorometers, may still output a small voltage when placed into a standard with a reference value of 0 (e.g. DI water). Since this voltage is very small, […]

    Setting Gain on a mV-485 Adapter

    Some analog sensors, such as a Turner Designs Cyclops-7 fluorometer, have different gain settings that allow the sensor to achieve high accuracy across a wide range of concentrations. When used with a mV-485 adapter, the gain setting is controlled within the adapter and can be changed using the process described below. 1. Establish a connection […]

    Connecting to a mV-485 Adapter

    NexSens mV-485 adapters can be used to connect sensors with voltageĀ outputs (e.g. 0-5 VDC) to the iSIC or SDL500 data logger when an analog port is not available. The adapter reads the mV output from the sensor and converts it to RS-485 Modbus format. Each adapter must be configured for the specific sensor to which […]
