5.2 Checking
CAUTION
Contact with the sample can lead to danger to the user!
Depending on the type of sample, suitable protective mea
-
sures must be taken (protective clothing, protective goggles,
etc.).
ORP sensors are not calibrated. You can, however, check ORP
sensors by measuring the ORP of a test solution and comparing the
value with the nominal value (see section 5.2).
1. Install the sensor in a flow through armature and provide the sample flow.
or
Submerse the sensor in the sample.
Prepare the test solution.
Step 1:
The sensor is in the sample.
The procedure is started from the measured value display with
<C> (see IQ S
ENSOR
N
ET
system operating manual).
During the check, the sensor is in maintenance condition.
All linked outputs remain in their current status.
