For VB1000 Light probes:
Plug your Probes into the Light Probe junction box in the right DIN jack marked Light Probes. If you have an older fiber-optic probe set the Probes will be permanently attached to the junction box. Make sure the toggle switch is set to Light Probe (right) position. Plug the DIN plug from the junction box into the Probe DIN jack on the front panel of your Acutron. Never force any DIN plugs in. Always rotate them until they slide in smoothly.
Supply power to the junction box by plugging the smaller AC-DC adapter for the Light Probe into a good power strip surge protector, then put the power plug into the Light Probe junction box. Make sure you do not put the larger, rectangular Acutron power adapter into the Light Probe.Power up Acutron and select Probe preset #1 – Circling the Dragon. Get to the treatment screen (half circle with 0 – 100 scale).
Remove any Q-Tips and touch the bare metal tips of the two Probes together. Make sure the metal probe tips are securely screwed on. The indicator on the display scale should move up to 100%, or very near to that. If the indicator does not move up check the toggle switch on junction box to make sure it is to the right Light Probe position. Make sure all connections are secure. If it is, and indicator does not move there is a detached wire in your Probes and they need to be repaired. Alternatively there could be a loose wire in the Acutron Probe DIN jack that is not supplying the Probe with power.
If your Probes pass Test A, press and release the trigger button on your Trigger Probe. Touch the metal tips of the Probes together and look at the meter. The indicator should deflect up to at least 90%. If it does this test is OK. Make sure the trigger is starting the current properly. If pressing the button does not do anything the trigger button may need repair.
Make sure your Probe junction box is plugged into the Acutron and the Acutron is powered up. On the junction box turn the top knob up to about the 3 o’clock position (white indicator pointing toward the right). Turn the lower knob all the way to the right for maximum light brightness. Look into the treatment end of the Probes. You should see a bright white light of two different shades. The amount of light should be approximately equal between the two Probes. If you have a fiber-optic probe set look into the treatment ends of the fiber-optic stems.
If no light is coming out of both Probes when the above instructions are followed check the AC-DC adapter for the Light Probe junction box. Is it plugged in to the junction box? If so the adapter may be defective. Get it tested or replace it.
If you do not see light coming out of either or both Probes the LEDs are defective and the Probes set will need to be repaired. Click here to open the Repair Requisition form.
When one probe light is on, and the other off in the Probes there are two possibilities:
A.The LEDs are burned out in one of the Probes.
B.This could also be caused if you plug the junction box DIN plug into the Acutron front panel Probe DIN jack upside down. It is possible to force it in that way, so remove it and rotate it until it slides in smoothly and easily. If you see any bent pins in the plug try to carefully straighten them out with a mini screwdriver.
If DIN plug is inserted properly and light is not coming out of one Probe only then the LEDS probably need to be replaced.
Check the Probe DIN jack on Acutron front panel – is it loose and wobbly? If so it probably needs repair.
For fiber-optic probes, when you don’t see light coming out of one or both of the light stems on the treatment end of the probe, it is more likely that the fiber-optic cable has broken. Again, repair will be needed.
For servicing, send both probes and junction box. Tag them with your name and phone number.
