Section Six – Validation and Calibration
Pre-Heat Temperature Calibration
Calibration of the temperature control system is recommended every six months for 32
°
C and
37
°
C set points. A Temperature Calibration Log is provided and may be copied for entry of
temperature calibration data.
1.
Place Calibrated Thermometer (p/n 65-233-401) in the 3/8 in. hole provided in the Tank
Cover (hole located furthest from Heater Assembly).
2.
Set Temperature Set Point to 32
°
C (see
Section 7 – Temperature Setting
) and allow it to
stabilize.
3.
Record set point temperature and sensor display temperature from the digital display on
the Control Panel. Record actual temperature from Calibrated Thermometer.
4.
Set Temperature Set Point to 37
°
C (see
Section 7 – Temperature Setting
) and allow it to
stabilize.
5.
Record set point temperature and sensor display temperature from the digital display on
the Control Panel. Record actual temperature from Calibrated Thermometer.
Adjustment of Sensor Display Temperature
CAUTION
The sensor display temperature has been adjusted at the factory and should not require any
additional adjustment. Adjustment may be made only when Calibration indicates more than
0.2
°
C difference between Display Temperature and Actual Temperature (see
Section 6 – Pre-
Heat Temperature Calibration
).
1.
Press both the
Up (↑) and Down (↓) keys simultaneously until you see “LOC” equal to “5”
(if “2”, change number using Up key to “5”).
2.
Press the
(
∞
)
key, then
press the
key repeatedly until you see “i.CA”.
3.
Add or subtract to the number in order to equal the standard temperature.
4.
After calibrating, press the
(
∞
)
key, then
press both the Up (↑) and Down (↓) keys
simultaneously until you see “LOC”, which needs to be changed to “2”. Press the
(
∞
)
key
to finish.
5.
Recalibrate per
Section 6 – Pre-Heat Temperature Calibration
.
