STARTER 3100C OPERATION 

 The first time you use the conductivity electrode, it should be calibrated before taking any 
measurement. Please also read the conductivity electrode instruction manual for reference. 
 

WARNING  

 Do not operate the equipment in hazardous environments. The 

equipment is not explosion protected. 
 
 

 

WARNING  

When using chemicals and solvents, comply with the instructions of the 

chemical producer and the general lab safety rules.

 

 

 

4.1 Calibration 

4.1.1 

Selecting a standard 

When using the 

STARTER 3100C

 conductivity meter, you have to select a standard for calibration 

(see 3.3).   

Press and hold the 

 enter setup mode, after press 

 to confirm the temperature 

unit and value. Then the current standard blinks. Use 

 or 

 buttons  to  select  the 

standards, press 

 to confirm. Press 

 to leave the setup mode. 

 
The 4 predefined standards are: 

10 

μ

S/cm 

84 

μ

S/cm 

1413 

μ

S/cm 

12.88 mS/cm 

Tables for automatic temperature compensation are programmed in the meter for each standard 
(see appendix).   

4.1.2 Performing 

calibration 

When performing calibration, Ohaus recommends using 

Auto End Point Mode.

 After powering 

the meter on, be sure the top of the screen shows 

 to ensure the meter is in 

Auto End point 

Mode.

   

 
Auto or Manual End point Mode:

 

o

 

Press and hold 

 to change the 

End Point Mode

o

 

When in Manual Mode, to manually reach a pH measurement or calibration value, 

you need to press button-

 when reading is stable and displays 

then the sample reading or calibration value freezes,  

 blinks 3 times and 

freezes on the display.
