Radiometer Analytical TitraLab TIM840 Guide D'utilisation page 60

• Monotonic IP (Inflection point detection with incremental addition
of the titrant, increments of equal size)
• Dynamic IP (Inflection point detection with incremental addition
of the titrant, increments of varying size)
b. Select the measurement mode: pH, mV or mV at imposed current.
c. Select the way the temperature is to be measured.
• Probe: temperature sensor is required during measurements.
• Entered: temperature is to be entered manually using the
keypad.
• Fixed 25°C: measurements are assumed to be performed at
25°C.
d. Enter the Number of tests, i.e. the number of times the method is
to be repeated.
e. If you want a message to be displayed upon starting the method,
select Notification = Yes then enter the message (3 lines of 32
characters maximum).
f. Select the way the cell grounding of the measuring electrode will
be performed:
• Reference: reference electrode connected to the Ref socket
on the titration system.
• Metal: metal electrode connected to the GND socket on the
titration system. For titrations in very resistant medium.
• Other: an electrode which does not belong to the electrode
system.
g. Blank: A blank or blank sample is usually a solvent used to dissolve
or dilute the sample. This blank may contain traces of the species
you are analysing. Select Yes for Blank when you want to subtract
the volume of titrant used to titrate the solvent from the volume
found for the dissolved or diluted sample.
