Notes:
• If the temperature is out of range, the "WRONG
BUFFER TEMP" message blinks on the LCD.
If the reading is too far from the expected value,
"WRONG BUFFER" blinks.
• For best results, use a calibration solution with
EC (or TDS) value close to the sample to be
measured.
• During calibration the meter compensates using
the 1.90%/°C coefficient. If the setup item "tc"
has been set to a different value, when exiting
calibration mode, the displayed value might be
different from the nominal standard value.
CUSTOM CALIBRATION
Calibration can be also performed with a custom cali-
bration solution.
• Immerse the probe into the custom calibration solution
and select the proper EC (or TDS) range. Press first
CAL to enter the calibration mode and then RANGE
(or NEXT) to enter the custom calibration.
Temperature reading can be manually fine-tuned as ex-
plained in this section.
Press SHIFT and CFM keys to enter
the temperature adjustment mode.
Both primary and secondary LCDs
will display the current temperature
reading for a few seconds, followed
by the default temperature reading.
Adjust the temperature value on the primary LCD using
the arrow keys. The maximum allowed adjustment is
±1.0
º
C around the current reading.
Press CFM to confirm. The meter returns to measure-
ment mode and displays the new temperature.
Notes:
•
Press SHIFT and CFM keys to escape without
changing.
• To enter temperature adjustment mode, the
probe must be connected and the meter must
be in ATC mode.
