14) Repeat step 13 for both a MID temperature (near 35 °C) and HIGH temperature (near
70 °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 each 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.
15) After all three temperature points have been taken; press [CALC COEF] to calculate
the new temperature coefficients for those probes which are marked. Unmarked
probes retain their previous coefficients. The current coefficients for one probe will
appear on the screen. Use the [VIEW NEXT] key to display coefficients for the other
probes.
16) Press the [PRNT COEF] key if a printout of the coefficients is desired.
17) 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 using the EDIT mode
described in section 3.3.1.
18) Check the accuracy of the calibration if desired, by repeating steps 9 through 12,
however, don't "mark" any of the probes for calibration. Adjust the temperature bath
to any values between 0 and 70 °C and visually compare readings.
19) Switch main console power OFF.
20) Re-install all temperature probes. Tighten all connections just past finger tight.
21) Cap the chamber fluid drain valve and refill the chamber fluid jacket with the
water/glycol mixture which was removed in step 4(B).
22) Replace all covers and panels. The system must not be operated unless ALL panels
are in place.
23) To print a calibration report, refer to section 4.2.5.
