OTZ (One Time Zero)
The One Time Zero is available for all photometer variants whereby
the zero adjustment is carried out in a 24-mm round vial with sample
water. It can be used if different tests are carried out with identical test
conditions and the same water sample. When changing methods, it
is not necessary to carry out another zero adjustment; the next test
can begin immediately. The zero adjustment is saved until the device
is switched off.
The zero setting can be repeated each time if necessary.
