Clearing the Stored Memory
Turn the TRACER on. Press and hold the ON/OFF button for 4 second the display
will briefl y display “clr” when the memory is cleared.
CALIBRATION
For the most accurate results, allow suffi cient time for the temperature of the
probe to reach the temperature of the sample before calibrating. This will be
indicated by a stable temperature reading on the display
Meter accuracy verifi cation should be performed on a periodic basis as needed.
If calibration is required, the meter must be in the salinity mode to perform a
calibration for salinity, or in the conductivity mode to perform calibrations for
conductivity, and TDS. The meter can perform a calibration and store the data
for one range in the salinity mode and each of the three ranges – low, medium
and high for the conductivity and TDS modes. The automatic calibration
recognition procedure will recognize salinity standard 3,000 ppm (medium)
and conductivity standards of 84 μS (Low), 1413 μS (Medium) or 12,880 μS
(12.88 μS) (High). (See Page 5). Always calibrate in the range closest to the
expected measurement value. For salinity samples within the range of 1,000 to
9,999 ppm salinity, calibrate with a 3,000 ppm calibration standard.
1. Fill a sample cup to 20 mL line with a calibration standard.
NOTE: The meter allows for a 1, 2, or 3 point calibration foe conductivity
and TDS. If calibration is done for more than one point, the lowest
concentration should be done fi rst to obtain the best accuracy. Calibrate
the ranges from low to high
2. Press the ON/OFF button to turn the TRACER on. Insert the electrode
into the standard. Tap or stir the sample with the Tracer to dislodge air
bubbles.
3. Press and hold the CAL/RECALL button for approximately 2 seconds.
“CAL” will appear and the display will fl ash.
4. The meter will automatically recognize and calibrate to the calibration
standard. The display will briefl y indicate “SA” and “End” and then
return to the measurement mode.
NOTE: “SA” will not appear if the calibration fails.
12
5. The calibration range indicator will appear on the display for each range
that is calibrated during a power on cycle.
Low Range, 84 μS/cm
L
Medium Range, 1413 μS/cm or 3,000 ppm SaH
M
High Range, 12.88 mS/cm (12,880 μS/cm)
H
NOTE: Each time the calibration mode is entered all calibration range indicator
will be cleared, but only the calibration data for the currently selected range will
be replaced. In the conductivity/TDS modes, the calibrations for the other two
ranges will be saved even though the indicators for those ranges are no longer
displayed. Calibration of all three ranges must be performed during one power
on period for all three calibration range indicators to be displayed.
