To use the current stored blank (displayed in the box) simply press
Use Current Blank
. This
will keep the blank that is displayed and no further input is required before entering the
ANALYSIS LOOP. To measure a new blank solution or enter a new blank value from the
keypad, touch the
New Blank
button and the
NEW BLANK
screen will open with 2 choices for
entering a new blank.
Touching the
Current Blank in Use
button will open a numeric keypad for manual entry of the
desired blank. (NOTE: It is a good practice to periodically measure a “reagent” blank to keep
tabs on how the meter is working and to verify that the current lot of reagents is free of
extraneous chloride. Keep the blank readings handy and build a “running average” of the blank
for each lot of reagents and use it as the blank for measurements.)
Touching the
Read New Blank
button will open a prompt screen, at which time, put the
electrode in the freshly prepared and cooled reagent blank and press read. If the measured blank
is within the acceptable range, the program will proceed to the
SAMPLE ANALYSIS
screen
and the actual analysis can begin.
