If the logging interval is less than 60 seconds, the instrument will always stay on. For inter- vals of 60 seconds or more, it is possible to choose to switch off the instrument between two consecutive logging sessions: the instrument will switch during sampling and then switch off immediately afterwards, thus prolonging the life of the batteries.

ELATIVE HUMIDITY PROBES The humidity probes for the DO9847 are of the combined humidity and temperature type: the hu- midity sensor is of the capacitive type, the temperature sensor is a Pt100. The probes are equipped with a module with a DIN 8-pole connector inside which is a microprocessor circuit with a perma- nent memory which stores the calibration data.

Page 37: Calibration Of The Pt100 Or Thermocouple Temperature Sensor
For combined probes, two distinct calibration procedures are contemplated: one for the tempera- ture sensor and one for the relative humidity sensor. Calibration of the Pt100 or thermocouple Temperature Sensor Save the case in which the temperature sensor is working in a particularly hostile or corrosive at- mosphere, or where, by mistake, its calibration has been endangered, the temperature probe does not normally require recalibration: it is advised to assess the need for new calibration carefully be- fore taking action.
Page 38 0) Full Calibration This calibration procedure erases the data of the previous calibrations. For a correct calibration of the probe the first point must be at 75%RH and the second point at 33%RH. On conclud- ing the second point at 33%RH, the instrument also proposes a third calibration point at 11%RH: if you do not want to use it, it is sufficient to press the <ESC/CLR>...

Page 40 8. Using the Up and Down arrow keys it is possible to correct the value with respect to the satu- rated solution at 75.0 proposed by the instrument. The temperature is the one measured by the Pt100 or TC sensor. To confirm the calibration point you can use the <REL> key or the <ENTER>...

Here are the reasons why two different operating modes have been chosen: when the sampling interval is short, all of the pressure measurements together re- flect quite faithfully the progress of pressure over the time.

Page 48: Note Concerning Do9847 Version
Note Concerning DO9847 Version AP471, AP472 and AP473 probes can work connected to a DO9847 only if this is provided with the 2.0 firmware version, or with a later one. Previous versions do not support these probes. To check which is your firmware version, open the menu and select INFO: VER 2 REV 0 indication corresponds to version 2.0.
Page 49 2) Moving Average The Record function provides a space average of acquired values in order to compensate ve- locity differences between a point and another in the pipe section. There is also another cause of error due to stream variations over the time: actually, a stream is not steady but, on the contrary, it can decrease or increase even in the same point.

Page 88: The Logging Function
OGGING FUNCTION The Logging function allows the recording of up to 32,000 measurements from the three input channels in the internal memory of the instrument with a time interval between two consecutive measurements which may be set from 1 to 3600 seconds. The data in the memory may be trans- ferred to the PC by means of the command on the Menu “...
Page 89 Example 1: you want to log the trend of three quantities (for example three temperatures) with an interval of 10 seconds; start and stop commands are given by the operator. A) Insert the three probes in the instrument. B) Switch on the instrument. C) If there has been a change in the probes at the inputs with respect to the previous measuring session, the instrument notifies the operator with the message: “WARNING! CHANGE OF ”.

APPENDIX Pt100 SENSOR The temperature response of the sensor used in the family of platinum probes (type Pt100) is de- scribed by means of the of Callendar Van Dusen formula (1). • − < 0°C • ≥ 0°C The coefficient C is considered equal to 0 for temperatures above zero. To find the value of the coefficients of equation (1) it is necessary to calibrate the probe on at least three different points: once they are known, these coefficients are inserted in the regression formula (2) to determine the temperature with relation to the resistance value of the sensor.
Page 117 for which the following relationships apply: α − • 00385055 δ − 499785 β − 10863 In (5), α coincides with the one defined in standard EN60751: it can be determined with a calibra- tion operation on only two points. Given the sensor resistance, the temperature is obtained with the regression formula (6): −...
