8 Configuration of the instrument
To configure the instruments according to Your needs proceed like follows:
Switch off the instrument.
Switch on the instrument and press mode-key (
)
during the segment test
(
)
until
the dis
play shows the first parameter “P_oF”
If a parameter should be edited, press key up or down (
), the setting of the
parameter will be shown.
You can be changed via up/down keys and receipt the changed parameter with

If there won’t be pressed any key for the time of
the power off time setting, the device will be switched off automatically to
save battery power (adjustable range 1 to 120 min)
automatic power-off is deactivated (continuous operating)

non-linear temperature compensation for natural water acc. to EN 27888
(ISO 7888) to measure ground water, surface water, drinking water and
purest water (factory setting)

Settings are kept
Restoring device to factory settings
Pressing
again stores the settings, the instruments restarts (segment test)
Please note: If there is no key pressed within the menu mode within 2 minutes, the
configuration will be cancelled, the entered settings are lost!
Note for temperature compensation: To measure the TDS value always use non-linear
temperature compensation for natural water (reference temperature = 25 °C).
To measure salinity the instrument automatically switches over to the non-linear
temperature compensation acc. to IOT (reference temperature = 15 °C)..
