Adjusting the Analyzer

  Heating Element Adjustment

The procedure for adjusting the heating 

element is described in the instructions 

supplied with the YTM15MA temperature 

adjustment set .

  Weighing System Adjustment

  To adjust the weighing system, perform 

calibration and adjustment as described 

in the following .

 Purpose

  Calibration is the determination of the 

difference between the weight readout 

and the true weight (mass) of a sample . 

Calibration does not entail making any 

changes within the weighing system .

  Adjustment is the correction of the  

difference between the measured value 

displayed and the true weight (mass)  

of a sample, or the reduction of the  

difference to a level within specified 

 permissible error limits .

 Features

  Calibration is performed externally with 

the following weight value:

–  MA35: 30 g; see “Accessories,” order no . 

YSS43-02

  You can have calibration and adjust-

ment results documented as a ISO/GLP- 

compliant printout (see the page after 

next for an example) .
