21. Calculate the variance in Heater Tooling height from end to end and front to back.
> The height variance of the Heater from left to right should be within ±0.005 inch
(±0.127 mm).
> The height variance between front and back of the Heater should be within ±0.005 inch
(±0.127 mm).
> If the tooling is determined to be out of level, call Asymtek Technical Support.
CAUTION! Only trained service technicians should attempt to adjust the level of the Lift
Tables or Heater Tooling.
22. Close the Dispenser Jog Commands dialog box to return to the Main Window.
Heater Tooling and Needle Heaters
Perform the following electrical and temperature tests, as applicable to your system configuration, to
make sure that the Heaters are functioning properly.
To electrically test Heater Tooling:
WARNING! Make sure that the Heater Tooling is cool before performing this procedure or
serious injury may occur.
1. In the FmNT Main Window, click on Tools.
2. In the Tools Window, click on

switch the Main Circuit Breaker
OFF (0). Lock out and tag out the power as specified in the
Safety section of this manual.
7. Open the Hatch and disconnect the electrical cable to each Heater Module.
8. Measure and record resistance between connector pins 1 and 2 for each Heater Module.
> The resistance for a Heater with one heating element should be 60 ohms.
> The resistance for a Heater with two heating elements should be 30 ohms.
