Operating Instructions Moisture Analyzer MA37

Care and Maintenance

Service

To ensure its continued weighing accuracy, we recommend performing regular 
servicing on your analyzer at least once a year . The Sartorius Service Center offers 
different service contracts for this purpose, which can be individually adapted to 
suit your needs (see also www .sartorius .com/service) . Each service produces a 
calibration certificate . The analyzer and its connections must undergo a technical 
safety inspection on a regular basis carried out by an electrician (e .g ., every 2 years) .

Repairs 

Repair work must only be carried out by trained service technicians . The analyzer 
must be unplugged during repair work . Unplug the power cable from the socket . 
Failure to do so may affect the measurement accuracy of your analyzer and pose 
a serious risk to the user . Contact the Sartorius Service Center or a Sartorius dealer 
to arrange for proper repairs .

Cleaning the Analyzer

Cleaning the Control Panel

Switch the display to standby mode to avoid modifying the settings for operation 
during cleaning .

t

  Select the menu key to switch to the method menu . 

t

  If you then select 

j

, the display is switched off . 

t

  To switch the display back on: Select 

j

 at the bottom left of the display . 

The moisture analyzer starts in the application most recently used before the 
analyzer was last switched off .

Cleaning the Housing

Disconnect the analyzer from the power before cleaning . Disconnect any data 
cables from the moisture analyzer . 
 

Never open the analyzer housing . The parts contained in the housing cannot be 
cleaned, repaired, or replaced by the operator . 

–  Make sure that no liquid or dust gets into the analyzer .
–  Remove the disposable sample pan and pan support from the analyzer .
–   Never use cleaning agents that contain solvents or abrasive ingredients, which 

can ultimately damage the equipment . 

t

   Clean the outside of the housing with a lint-free cloth and mild cleaning agent 

(e .g ., isopropanol) . 

t

  Then dry the analyzer with a soft cloth .
