Instruction Manual

4-6 Heater Controls
Figure 4-5
The Input tab in Figure 4-5 is used to define the input types for each loop. Unused loops which do not
have heaters attached are defined as “skipped”. Also, any process offsets to make up for signal
inaccuracy are set here. All settings in this dialog box are set for each loop in your system at the Asymtek
factory prior to shipping.
Input Reading Offset can be used to make up for a calibration offset. The thermocouple inside of the
heating element may register a value that is different than the temperature of the part. To adjust for this
offset, use an independent thermocouple and determine the true temperature of the part you are heating.
The difference between the true temperature and the PV is the offset. To add this information to this
menu, change the
Input Reading Offset. A positive number increases the reading. Input Filter is usually
used to compensate for noisy signals. However, the dispensing systems are shielded to avoid noise.
WARNING! Only trained engineering personnel should attempt to make offset measurements
or change any settings in this dialog box.
Select the Output tab.
