Example 2: Calibrating multiple probe levels
The following example produces calibration values for use with temperature
probes connected to two different data analyzers. Three calibration points
are used.

Values a and b obtained by this program are specified with Command 9 on
the data analyzer whose probe is being calibrated to the reference probe (the
CH2 probe in this example) before performing actual sampling.
{9,Channel,1,a,b}"
List 6
Send(List 6)
Specifies that the reference temperature
probe is connected to CH1.
Specifies that the temperature probe being
calibrated to the reference probe is con-
nected to CH2.
Specify three points (approximate maximum,
minimum, and midpoint of sampling range)
for this example.
Inserting a display halt command (^ )
causes execution to stop when setup is com-
plete. Press [EXE] to continue.

(“Channel” is the specification of the chan-
nel to be used for sampling.)
