Note
For ORP electrodes with platinum electrode, please observe the instructions
in section A
CTIVATING PLATINUM ELECTRODES .
Commissioning Prepare the combination electrode for measuring as follows:
 TruLine ORP 50: Open the refilling opening for the reference electrolyte
solution.
The refilling opening must always be open during measurement!

opening
 Remove the watering cap from the electrode tip. Possible salt deposits in
the area of the watering cap do not affect the measuring characteristics
and can easily be removed with deionized water.
Note
Please keep the watering cap. It is required for storing the combination
electrode. Always keep the watering cap clean.
 Connect the combination electrode to the meter.
 Measure with the combination electrode according to the operating man-
ual of the meter and observe the following rules while doing so:
General rules for
measuring
 TruLine ORP 50: Make sure the refilling opening for the reference electro-
lyte solution is open.
 Avoid displacement of the sample solution from one measurement to the
next by taking the following measures:
– Briefly rinse the calibration beakers with the solution the beakers are to
be filled with next.
– Between measurements, rinse the combination electrode with the so-
lution specified below. Alternatively, you can also rinse the combination
electrode with deionized water and then carefully dab it dry.
 Immerse the combination electrode in the solution in a vertical or slightly
tilted position.
