Zero Adjustments
In the StarBright, all adjustments, including zeroing internal circuits, are done from the software.
This ensures simple and accurate realignment. It is recommended to re-zero the StarBright every 2
months for best performance.
To zero the instrument:
1.
Disconnect the sensor, turn the instrument off and then back on again, so the StarBright can
identify that no sensor is connected. An "Initializing" message will be displayed.
2.
Let the StarBright run for at least 30 seconds before performing zero adjustment. Make sure
the sensor is in a quiet environment (without electrical noise) and not subject to pulsed
radiation.

Press
Zero
and
Start
. Wait until “Zeroing completed successfully” appears.
4.
Press
Save
to save the new zero values to the instrument.
5.
Press
Exit
to return to the main screen.
For Thermopile Sensors only:
For best results with Thermopile sensors, it may be necessary to do the procedure once with the
sensor disconnected, then afterwards again with the sensor connected.
To zero the instrument against Thermopile sensors:
1.
After completing steps 1-4 above, connect the sensor and make sure it is at room temperature
and well shielded from any stray thermal power. It is recommended to lay the sensor with the
absorber face down on the table.
2.
Switch the instrument off then on again with the sensor connected.

For Pyroelectric and Photodiode Energy Sensors:
In addition to zeroing the meter, as described previously, it is important to zero the meter against
the sensor you are using the first time. After you have done zeroing, you do not have to do it again
when used with the same type of meter. If you have zeroed it against a different type of meter,
then a different value has been saved and therefore when used with this StarBright, you should
zero it again.
