Manual temperature compensation
The manual temperature compensation only influences the
reading if a pH probe without a temperature sensor is con-
nected. The instrument can therefore be adjusted to the
temperature of the measurement medium.
This function is only available with a connected BNC module
(pH3) if a pH probe without temperature sensor is connect-
ed. The temperature can then be adapted to the temper-
ature of the medium being measured.
1. Open manual temperature compensation mode:
