The cursor will flash and the meter will begin to count up to 40 seconds. After the 40 seconds, the
result will be displayed. Record this result (this result is automatically stored in FE2).
NOTE: If your
result is 2.2 ppm or greater
, repeat Step 6 by using a second TPTZ Strip within the next 30
seconds. This assures that all iron has reacted with adequate TPTZ reagent and that the full
range of 7.5ppm gives best accuracy.
