Warm-up period For routine measurements without special accuracy require-
ments, a warm-up period of 5 minutes is sufficient. For high
precision measurements, the warm-up period should be 30
minutes minimum. This is also valid when you want to cali-
brate your instrument. Only then we can guarantee that the
instrument measures with the accuracy specified in
