System Calibration
Screen 9d: System Calibration (4/5)
Temperature displays current reading from the
temperature probe with the offset applied. If LectroCount
is not equipped with a temperature probe, the display will
show dashes. This eld allows entry from a Weights &
Measures calibrated thermometer.
To calibrate temperature probe, run enough product
through the meter to allow temperature to stabilize.
Compare Temperature reading with current Weights &
Measures thermometer reading. If the readings do not
match, enter the Weights & Measures reading in the eld
edit window for Temperature. This value will overwrite
the previous value and the Offset eld will be recalculated
by the LectroCount.
Offset adjustments are limited to ±0.3°C (±0.54°F).
Adjustments greater than these offset values require
replacement of the RTD Probe.
Offset represents the difference between the ofcial
Weights & Measures temperature reading and the
LectroCount probe’s temperature reading. The offset
is automatically calculated if an entry is made in the
Temperature eld. If a temperature probe is not present,
this eld will show dashes.
If a Weights & Measures temperature reading was not
entered in Temperature, subtract Temperature value
from Weights & Measures temperature reading. Enter this
value in the eld edit window for Offset. If the difference
is a negative number, enter “-” before the value.
Offset adjustments are limited to ±0.3°C (±0.54°F).
Adjustments greater than these offset values require
replacement of the RTD Probe.
Temperature Unit is used to dene the temperature
unit to be used for the application. The two options for
Temperature Unit are Deg. C (degrees Celsius) and Deg.
F (degrees Fahrenheit). Move pointer to desired option
and press ENTER to accept.
RTD Slope and RTD Offset are used for factory calibration
of the LectroCount and are not editable.
RTD Slope indicates slope used to calculate the raw
temperature value from the raw ADC value.
RTD Offset indicates offset used to calculate the raw
temperature value from the ADC value.
