[labnetwork] Help with Neitronix Mask Aligner power supply.

[Paul Maciel]

Hello Patrick,

How old is your lamp?  The voltage and current values listed in the manual are for a new lamp.  As the lamp ages these values change and the intensity also decreases.  You should also have the power supply in constant power mode when you take these measurements.

Regards,
---Paul

Hello Group We are having several problems:

1. The power cannot be adjusted to 350 like in the picture you provided in the manual.

It can only be adjusted from -179 to 59 (at 59 it starts beeping)

I think this is the biggest problem.

We tried ro adjust it in both CP and CI mode with the same bad results.

2. If we multiply the voltage shown and the current shown, then we get a different value for power than the one shown. Why is that? In the manual, that is not the case. The voltage (67.3) multiplied with current (5.2) gives the power shown (350) for an intensity of 12.0.

3. We need to set the tool in intensity constant mode. Probably we need to fix the other problems first, but right now we just tried it by following exactly the instructions and we cannot finetune with SET button because it doesn’t work (rotates but the intensity value doesn’t change).

Also whatever settings we try in intensity constant, it just beeps continuously because the power goes straight to 59.

Has anyone else encountered this problem.   Thanks  Patrick
