STEP 4: SYSTEM CALIBRATION (CONT'D)
A
DECIMAL
This field allows you to choose between whole units, tenths and hundredths of a unit. Press ENTER
and the cursor will drop to the bottom line. Use 1 to scroll between WHOLE, TENTHS, and HUNDR.
When the desired choice is displayed press ENTER and the cursor will move to the top line.
Press 1 and the cursor will move to:
A
RESIDUAL
Volumes less than the least significant digit can be rounded into that digit or truncated (thrown away)
depending on the selection mode. Press ENTER and the cursor will drop to the bottom line. Press 1
to scroll between ROUND and TRUNCATE. When the desired choice is displayed press ENTER and
the cursor will move to the top line.

System Calibration - Screen 3
| TEMP OFFSET
25.53 0.00
TEMP
This field displays the current temperature reading from the RTD temperature probe and allows one
to enter a corrected value from a Weights & Measures thermometer. If the LCR-II is not equipped with
the optional Electronic Temperature Volume Compensation (ETVC) Kit, this field will read
To make a correction:
Run enough product through the meter to allow the temperature to stabilize. Compare the
TEMP reading with the current Weights & Measures thermometer reading. If the readings are
different, the Weights & Measures reading should be entered. Press ENTER and the cursor
will drop to the bottom line. Enter the new value. The new value will overwrite the previous
one and the OFFSET field will be recalculated by the LCR-II. Offset adjustments are limited to
±0.3°C (±0.54°F). Adjustments greater than this limit require replacement of the RTD probe.
Press ENTER and the cursor will move to the top line.
Press 1 and the cursor will move to:
OFFSET
The offset represents the difference between the official Weights & Measures reading and the LCR-II
RTD reading. The offset is automatically calculated if an entry is made in the previous field.
If a Weights & Measures thermometer reading was not entered in the previous field, subtract the
value listed in the TEMP field from the Weights & Measures measurement. Key in the difference
in the offset field. If the number is negative, use on the Lap Pad to change the sign. Adjustment
is limited to ±0.3°C (±0.54°F). Any adjustment larger than ±0.3°C (±0.54°F) generates a "RANGE
ERROR" message and requires replacement of the RTD probe.
