When the "
" symbol stops blinking, the reading is stable. The "CFM" indication starts
blinking on the LCD asking for confirmation.
Press SHIFT+CFM to confirm the calibration.
If everything is satisfactory, the meter displays the "Stor Good"
message and returns to measurement mode.
Notes
I.
The meter uses 1.90%/°C compensation factor during calibration. If the setup item
"tc" has been set to a different value, when exiting the calibration mode the value
displayed on the upper LCD could be different from the nominal buffer value.
II.
It is possible to set the cell constant value directly without following the calibration
procedure. To set the cell constant enter the setup mode and select "CEL" (see SETUP
for details).
III.
Press SHIFT+CFM to confirm. The meter returns to measurement mode.
NaCl CALIBRATION
Calibration is 1-point at 100.0% NaCl. Use the MA 9066
MA 9066
MA 9066
MA 9066
MA 9066 calibration solution (sea
water solution) as a 100% NaCl standard solution.
• To enter NaCl calibration select the NaCl from “RANGE” key and press CAL.
• Rinse the probe with some of the calibration solution or deionized water. Immerse the
probe into
HI 7037
solution. The sleeve holes must be completely submerged. Tap the
probe repeatedly to remove any air bubbles that may be trapped inside the sleeve.
• The indications "STD" and "CAL" are displayed. The upper LCD shows the uncalibrated
NaCl reading in percentage. The lower LCD shows "100".
• When the " " symbol stops blinking, the reading is stable. The "CFM" indication
starts blinking on the LCD asking for confirmation.
• Press SHIFT+CFM to confirm the calibration.
• If everything is satisfactory, the meter displays the "Stor Good" message and returns to
measurement mode.
Note: If the uncalibrated reading is too far from the expected value, the calibration is
not recognized. The "CFM" indication does not appear; the "
" and "STD"
symbols blink to signal wrong or contaminated calibration solution.
