Selecting the Range
Thermopile heads cover a wide range of powers, from
microwatts to 1000s of watts, depending on the type of head in
use. In order to provide accuracy at each end of the range, the
electronics of the USB Interface Unit must be configured to
work in a range that is most suited to your needs.
To configure the range when you know the approximate
range of the expected readings:
Select the range from the
Range
drop down list in the
Measurement Parameters Area. The instrument will
configure itself according to the selected range.
Figure 23: Range Drop Down List
To configure the range when the range of the expected
readings is not known, or if highly varying readings are
expected:
Select
AUTO
from the
Range
drop down list in the
Measurement Parameters Area. The instrument will
configure itself according to the selected range.
Note: AUTO instructs the instrument to configure itself in
the lowest range possible that is higher than the latest
readings. If the readings exceed 100% of the present
range, the instrument reconfigures itself for the next
