9  Operation of the Logger 

The device supports two different logger functions: 
 

„Func-Stor“:

  

each time when „store“ (key 6) is pressed a measurement will be recorded. 

„Func-CYCL“:

  measurements will automatically be recorded at each interval, which was set in the logger 

menu ‚CYCL‘ until the logger will be stopped or the logger memory is full.  
The recording is started by pressing „Store“ 2 seconds. 

For the evaluation of the data the software GSOFT3050 (V3.5 or higher) has to be used. The software also 
allows easy configuration and starting of the logger. 

When the logger is activated (Func Stor or Func CYCL) the hold and auto hold functions are no longer 
available, key 6 is solely used for the operation of the logger functions. 

9.1   

„Func-Stor“: Storing Single Measurement Sets 

Each time when „store“ (key 6) is pressed a measurement and its time stamp will be recorded.  
The recorded data can be viewed either in the display (when calling the configuration an additional menu 
„REAd LoGG“ is displayed, see below) or by means of the interface and a PC with GSOFT3050-software. 

The logger stores the current measuring, independent from the stability of the value. 

Max. number of data sets: 

1000  

A data set contains: 

- oxygen concentration in mg/l or ppm 
- oxygen saturation in percent or partial pressure in hPa or mmHg 
- temperature value at the time of recording in °C or °F 
- absolute pressure in hPa or mmHg or depth in m  
- time and date of the recording 

After each recording „St. XX“ will be displayed for a short time. XX represents the number of the recording. 
 

Input of the measuring point 

“L-Id”: Selection of measuring point via keys 

 or 

Number 0…19999 or text assigned to number 1…40  
(Comfortable assignment of texts can be done with gratis software GMHKonfig)  
Confirm input with 

„store“. 

 

When logger memory contains recordings already: 

When „Store“ is pressed for 2 seconds, the choice for clearing the logger memory will be displayed: 

 
The selection can be made by 

 (key 2) and 

 (key 5). "Quit" (key 6) enters the choice. 

 

If the logger memory is full, the display will show: 

 

 

 
Viewing Recorded Data 

Within the „LoGG Stor“ function the logger data can be viewed directly in the display not only by means of a 
computer (like at „Func CYCL“): press 2 seconds „Set“ (key 4): The first menu displayed now is „rEAd LoGG“ 
(read logger data). After pressing 

 (key 3)  the measurement recorded last will be displayed, changing 

between the different data referring to the measurement also is done by pressing 

.  

Changing the measurement is done by pressing the keys 

 or
