6.2. Perform zero calibration
WORKSTEP PROCEDURE
1. Prepare system
for zero
calibration. 1.1: Prepare photometer as described in Section 6.1.
1.2a: Zero calibration in the sample line:
If clean, bubble-free water is in the sample line (e.g. after CIP clean-
ing), a zero calibration can be performed without disassembling the
instrument. If this is not possible, proceed according to step 1.2b.
1.2b: Zero calibration outside the sample line:
Remove photometer without previously emptying the
sample line.
The photometer can be removed from a line only when the line is
completely empty. If this is not the case, flooding and damage to
equipment as well as bodily injury may occur.
1. Ensure that the sample line is empty.
2. Remove the photometer (1) from the sample line and submerge
the measurement opening (2) in clean, bubble-free water.
The measurement opening (2) must be completely submerged
in the water and no external light is allowed to penetrate. If
necessary, cover with a black cloth or use a
non-transparent
container (3). A transparent container is used here only for illustrative
purposes.
