Use test resistor Carries out the GLP test with 6.2109.030 Test
resistor.
Resistance Resistance in ohms (10 k Ω for 6.2109.030).
• Enable the Use test resistor option and enter the Resistance of
the 6.2109.030 Test resistor in ohms. Afterwards, click on
<Next> .
• For each channel in sequence, connect the 6.2109.030 Test
resistor to the electrode connections 20 20 and click on <Next> .
• Continue with step 4.
3 Carry out GLP test with standard solution
• Insert a measuring vessel filled with 60 mL distilled water
together with a measuring vessel cover into all channels (see
section 4.6.3).
• Click on 763 PVC THERMOMAT CONTROL / Tools / GLP test /
Conductivity and click on <Next> in the GLP test window.
Use standard solution Carries out the GLP test with standard solu-
tions.
Conductivity of standard solution
Conductivity of the standard solution filled into
the measuring vessels in µ S/cm.
A solution of c(KCL) = 1 mmol/L, prepared
from the 6.2301.060 Conductivity standard (KCl
0.1 mol/L) available as an option, can be used
as standard solution. The conductivity of this
standard solution is:
