5 Move the sensor gently several times before letting it stand.
6 Wait until both the redox and the temperature value are stable.
Then press [Enter] to save the result.
With difficult samples, it may take 15–20 minutes until the
reading is stable. With a freshly calibrated sensor, it may take
even longer. If the Chematest 35 switches off before the
measured value has stabilized, switch it on again and select
the <Redox/ORP> method again. This will not affect the
stabilization of the sensor.
7 Next you can optionally select an ID and/or a user name. This
procedure is described in detail on 17.
8 After use, rinse the sensor tip with clean water.
Automatic Shutoff
When the instrument is waiting for a user input (e.g. when the mea-
surement result is displayed) and no key is pressed for 10 minutes,
the instrument shuts off automatically to save power. This affects
the storage of measurement results in the same way as pressing
the [Exit] key. See
Step 3: Display and storage of the measured re-
sults, p. 17
for details.
