3-18 Setup and Operation
The calibration coefficients, XS, and Z values are unique to each sensor head, and may be
found on the calibration sheet shipped from the factory. The Band Broadening coefficient is
1.15 for all sensor heads.
The calibration coefficients are stored in the LI-7500 control box. To change these values,
edit them and then click the check boxes under Values to Update. Click on the Update
Selected button to send these values to the LI-7500 for implementation. Click the Cancel All
button to change any edited values in the window back to the state they were in before editing.
The Head Serial Number displays the serial number of the LI-7500 sensor head that is
associated with the coefficients.
When exchanging sensor heads, it is necessary to change calibration coefficients, and to redo
the zero and span.
HINT: The easiest way to get the calibration coefficients, zero, and span updated for a sensor
head is to make use of the “Save Configuration” and “Open Configuration” (see File Menu
starting on page 3-38).
Changing Sensor Heads
Sensor heads are freely interchangeable between control boxes. However, the control box
must have the correct calibration coefficients, and current zero and span information, for the
sensor head attached to it. This can be done by hand, or "automatically".
