nanodac RECORDER/CONTROLLER: USER GUIDE4.4.1 Channel Main (Cont.)Sensor Break type (Cont.)Input sensor break detection is not supported for secondary inputs. The internal circuitacts as a ‘pull up’ on the secondary input which therefore saturates high in the event ofa sensor break.Fault Response Specifies the behaviour of the recorder if a sensor break is detected or if the input isover driven (saturated high or low).‘None’ means that the input drifts, with the wiring acting as an aerial.‘Drive High’ means that the trace moves to (Scale High +10%). ‘Drive Low’ means thatthe trace moves to (Scale Low -10%), where the 10% values represent 10% of (ScaleHigh - Scale Low).Sensor Break Val A diagnostic representation of how close the sensor break detection circuitry is to tripping.Measured ValueThe (read only) input channel measured value before any scaling or linearisationis applied.Measured Value2 As ‘Measured Value’, above but for the secondary input.Internal CJ temp The (read only) temperature of the internal cold junction associated with this channel.HA030554Issue 7 Nov 12Page 83
