9 Troubleshooting

Output temperature is not stable

The laser pointer does not emit light
Cause Action
There is a source of intense
electromagnetic waves, such
as a high-frequency power
supply. Increase the distance from the
electromagnetic wave source,
or install an electromagnetic
wave shield.
Air flow from a fan or other
source is causing the
temperature of the unit or
object to be unstable.
Shield the unit and object from
the air flow.
The temperature of the unit is
constantly changing due to
heat from a heater or other
source.
Install a thermal shield plate or
insulate so that the unit
temperature is stable.
Cause Action
The laser output port is
blocked.
Remove dirt and foreign
matter from the laser output
port.
Emission stopped due to
external electrical noise. Wait briefly and then press the
button.
Power is not supplied. Check the power/output cable.
