4.2.3 2-point calibration
2-point calibration is not carried out automatically.
A 2-point calibration procedure can be started manually at any time if
necessary. For manual 2-point calibration, the enclosure has to be
opened to connect a second calibration standard.
Proceed as follows to carry out a 2-point calibration procedure:
Opening the enclosure 1 Open the enclosure of the P 700 IQ.
2 If the ambient temperatures are under 0 °C, make sure that the
liquids do not freeze during the calibration procedure.
• Leave the enclosure of the P 700 IQ open for as short a time
as possible
• Only carry out a manual calibration procedure when the inte-
rior of the P 700 IQ is warmed up (15 °C ≤ T
Interior
≤ 40°C).
3 For conveniently working on site:
Dock an IQ S
ENSOR N ET terminal onto an MIQ module in the vicin-
ity of the analyzer, or onto the MIQ/WCA 232 module in the ana-
lyzer.
