Configuration Parameters

Perhaps the most important parameters are the upper and lower temperature limits, as these
can be used to limit damage to the sample or equipment and to prevent hazards resulting
from heating of the sample.

Accessing the parameters

1. In STOP status, use the arrow buttons
2. Hold FUNC for approximately two seconds until the system 'beeps'.
This enters the configuration mode. The Upper display shows 0000 and the Lower
display shows PASS.
The system is prompting for the passcode, which must be entered within ten seconds.
3. Enter the four-digit passcode (1111), using the arrow buttons to change the flashing
digit and FUNC to move to the next digit. Press FUNC after the fourth digit to input the
passcode.
The flashing Lower display shows the parameter number (for example, P-01), the Upper
display shows the corresponding value and parameters can now be modified.

Setting the parameters

1. Whilst the lower display is flashing, use the arrow buttons to move between the
parameters.
2. Once the desired parameter has been selected, press FUNC.
The Upper display will flash.
3. Use the arrow buttons to increase (or decrease) the value shown.
4. Press FUNC to set the value.
The Lower display flashes.
5. The arrow buttons can be used again to select a parameter.
6. Hold FUNC for two seconds until the system 'beeps' to return to the STOP status.
