Then press <ENTER>. The LOW temperature value just entered, and the values of
the marked probe are automatically saved to memory for later computation of
calibration coefficients.
Note -
If a mistake was made during the temperature entry mode, use
[OOPS] rather than <ENTER>. This will cancel the
temperature entry mode and restore the previous "standard" and
"marked" probe values to memory. For instance, [OOPS] could
be used if the operator wanted to take the LOW temperature
point, but had mistakenly pressed the [MID TEMP] key.
9) Repeat step 8 for both a MID temperature (near 25 °C) and HIGH temperature (near
50 °C). Be sure to use the appropriate [MID TEMP] and [HIGH TEMP] keys.
Note -
Using the [LOW TEMP], [MID TEMP], or [HIGH TEMP] key
more than once allows the previous point of the thermistor to be
over-written with the most current measured value. The
reference thermometer value will also be over-written with the
new value entered. The data stored is that which exists on the
screen in the "Count" column when the [LOW TEMP], [MID
TEMP], or [HIGH TEMP] key is pressed.
10) After all three temperature points have been taken, press [CALC COEF] to calculate
the new temperature coefficients for the probe which is marked. Unmarked probes
retain their previous coefficients. The current coefficients for the marked probe will
appear on the screen.
11) If a printer is attached, a calibration record of the temperature points and calculated
coefficients is printed. Press the [PRNT COEF] key if additional printouts are
desired. This is the only opportunity to print this report. Upon leaving this screen,
the data used for report generation is lost (with the exception of the calculated
coefficients being displayed.)
12) To update the calibration with new coefficients, press the [SAVE QUIT] key. To
abort without storing these new coefficients, press the [EXIT QUIT] key.
Note -
If the new coefficients were printed but not SAVED, the new
coefficient values may be entered later using the EDIT mode
described in section 3.3.
