Without temperature sensor: manual input
of temperature of solution 1
You can enter the actual temperature of the buffer so-
lution using the

keys.
The value is stored when you press the [Store] key,
and the system shows the next calibration step.
In the case of 1-point calibration, the status of the elec-
trode is then displayed (only asymmetry potential, slo-
pe optimal = 59.2 mV/pH); the unit then switches to
the standard measuring mode MEAS.
After 1-point calibration, the
∆
!
signal is permanently
shown in the display.
The user should be aware that measuring errors can
occur with 1-point calibration, particularly with results
that are a long way from the calibration point.
2-point calibration is therefore always advisable.
Clean the electrode using deionised water
and dry carefully.
9.4 Calibration point 2: 'CAL. 2'
(only with 2-point and 3-point calibration)
Insert the electrode and the temperature sensor (if pre-
sent) in buffer solution 2 (e.g. Tintometer standard
buffer solution pH 4.00).
In the case of manual buffer setting, [Pt.1] appears in
the secondary display. You enter the pH value of the
respective buffer solution using the

then confirm the input by pressing the [Store] key.
