(6) The brown at the middle of test paper and the lower pink color indication represent the additive state
for rust prevention, and the proper range is that the meeting numerical value of brown (vertical) and
pink color (horizontal) locates in the range of 0.3 to 0.8 at the color list of label on the test paper
storage bottle.
(7) In case of less than 0.3, replenish the additive for rust prevention (DCA4), and in case of more than
0.8, pour out the cooling water about 50% and then readjust the density after refilling with clean fresh
