11.3.1.2  Setting of dew point sensor FA 410 

 
In this menu the dew point unit can be selected. The following units are preset ex factory: 
Dew point in °Ctd, temperature in °C and relative humdity in % RH 
 

ƒ

Setting of the humitidy unit

: (ºCtd, g/m3, g/kg, ppm etc.) Attention: ppm (V/V) and g/kg 

require the input of a reference pressure (absolute line pressure) 

ƒ

Setting of the reference pressure

: Required for ppm (V/V) and g/kg (absolute line 

pressure) 

ƒ

 For 

the 

atmospheric dew point

 please set the absolute line pressure. In case of this 

measuring unit the dew point under atmospheric conditions is calculated by means of the 
absolute line pressure. 

11.3.2  CS Analogue sensors (pressure sensor, clamp-on ammeter,  
            temperature sensor, …) 

 
DS 300 mobile version has 2 resp. 4 analogue input channels. The analogue input channels 
are not automatically recognized so the analogue sensor for the respective channel has to be 
selected. The analogue inputs are preconfigured ex factory, however they can be freely 
adjusted via the keypad. 
 
For this purpose the menu point "sensor setting", cannel 3 to 6 has to be selected. The 
following options are available: 
 

"Select sensor"

:  

In case of DS 300 mobile version there is a list of 6 sensors  

ready for selection. Please choose the required sensor.  

In order to complete the list with customer-specific sensors  

these customer-specific sensors can be defined by means of  

the software "DS 300-P configuration tool" and transferred 

to DS 300 mobile. 

"Show settings"

: 

In this point the sensor-specific data are indicated. 

"Calibration offset"

: 

Here possible zero-point errors of sensor and DS 300 can be  

adjusted. Typical example: One point calibration of a pressure  

sensor . The adjustment value stays stored in DS 300 in the  

 respective 

measuring 

channel. 

"Delete calibration offset"

:  Here the measured value entered under "calibration offset" can 

 be 

deleted.
