Preparation

Start-up

The interior body (pH electrode) is ready for calibration.
– On unpacking, check the pH electrode for
mechanical damage. Report any damage imme-di-
ately to your METTLER TOLEDO supplier.
– Remove the watering cap, cap sleeve, membrane
body and briefly rinse the sensor with de-ionized
water.
– After rinsing, the sensor should only be dapped dry
with a tissue. Do not rub the pH sensitive glass,
since this can lead to electrostatic charging and
sluggish response times.
– Check inside the pH sensitive glass for the pres-
ence of any air bubbles and remove same by gen-
tly swinging in a vertical plane (shaking down as
with a thermometer).

Before using the sensor for the first time, make sure that
the interior body (pH electrode) is well fixed into the steel
body. The VP connector must not be rotated in the shaft.
If so, the inner part has to be fixed by tightening the small
hexagonal screw below the connector.
