• Verify the engagement is correct by pressing
ENGAGE
and
DISENGAGE
. Carefully
observe as the sample probe & cooling assembly engage, and make certain the sample
tube’s height position is correct using the sample tube Height Positioning Fixture if
necessary. Also, verify the sample tube is properly clamped. If adjustments need to be
made, use the displayed icons to adjust, followed by pressing
LEARN
.
• Press
EXIT
after the proper engagement position is obtained.
7.6 Probe resistance
To change the probe resistance, press
PROBE RESISTANCE
. The user is prompted to select a
user. Enter the password. The
Probe Resistance
screen opens. (Figure 7.15)
This screen is where the user can change the sample probe resistance, sample probe Lot
Number, and the cooling block resistance. Change the values only if the sample probe or
cooling assembly were replaced. The correct resistance values and information were set at the
factory. If these values are changed to incorrect values, the performance of the instrument is
directly affected.
After making a change to one or both resistance values, the instrument requires calibration, and
does not allow the user to run a sample test until a successful calibration occurs.
NOTE:
CHANGING THE RESISTANCE OF EITHER THE SAMPLE PROBE OR COOLING
BLOCK RESISTANCE IS NOT ADVISED UNLESS THE SAMPLE PROBE OR COOLING
BLOCK HAS BEEN REPLACED. THE OSMOPRO IS SHIPPED WITH CORRECT
RESISTANCE VALUES AND CHANGING THESE VALUES CAN NEGATIVELY IMPACT THE
PERFORMANCE OF THE INSTRUMENT. IF A RESISTANCE VALUE IS CHANGED, THE
OSMOPRO REQUIRES CALIBRATION AND CANNOT PERFORM A SAMPLE TEST UNTIL
SUCCESSFULLY CALIBRATED.

7.6.1 Changing sample & block resistance
To change the sample and or block resistance, press the keyboard icon. The
Keyboard
screen
opens (Figure 7.16). Here the user can enter the new resistance value. Press
ENTER
