The "bat(tery)" or "accu" setting controls different
capacity utilization of the battery or rech. battery.
bAt means:
the capacity is used up to 6.2 V.
Accu means :
the capacity is used up to 7.0 V.
During operation with mains unit, the rech.
battery is only charged as long as the instrument is
on. Should the auto off function be on, "PSU"
appears in display once the instrument has
switched itself off, to inform the user that the
battery is still being charged.
If you want to send the measuring results to the
infrared printer (available as option), the trans-
mitting function must be activated by confirming
the setting "yes Ir".
Should you not need the IR printer, the use of the
instrument is facilitated by confirming the setting
"no Ir".
You can store electrode (calibration) data for two
separate electrodes (e.g. a laboratory electrode
and a field electrode). The electrode (data)
activated in the configuration menu is activated
during the measurement and can be altered
through calibration. When effecting a
measurement you must activate the electro
de(calibration) data which corresponds with
the electrode used (
electrode, pH2 e.g. field electrode).
no pH deactivates the pH part of the
measuring instrument, so that the conduc-
tivity/temperature measuring instrument is
easier to use.
