c. The standard value is stored and the meter automatically switches to standard
two as indicated by the “CAL2” on the display in the lower field.
7. Rinse well with deionized water and gently blot the electrode with a lint-free
tissue to remove water drops before moving to the next beaker or field sample.
8. Continue from the lowest to the highest concentration standard to reduce the
potential carryover effects.
9. If doing less than five calibration points and if this is your last calibration point
press the MEASURE key instead pf the CALIBRATE key to accept the value and
return to the measurement mode.
10. Repeat steps 5 and 6 for each standard.
11. After the standard value for the last standard has been entered the cell constant
will be displayed automatically CELL appears in the lower field while the actual
CELL constant appears in the main field. Then the meter automatically advances
to the measure mode. The probe icon is displayed above the main field.
To Take a Conductivity Measurement
Rinse electrode and place into sample. Record conductivity directly from the main
meter display when the mS/cm or μS/cm icon stops flashing indicating a stable
value. Temperature is displayed in the top left corner of the display.
