2.1.1 - Probe Settings

There are two different references to control the thermal block: Internal
Reference and External Reference.
The Internal Reference is a sensor built into the block.
The External Reference is an option for more accurate measurements. The
control reference comes from a Standard Sensor placed inside the insert, among the
DUT (devices under test). This Standard Sensor, with Callendar-Van Dusen parameters,
eliminates adjustment errors and block loading effects.
It can be used both in control and measurement mode. When used in
measurement mode, the probe indication is displayed on the screen and the control is
made by the internal probe.
Fig. 08 - Choosing the Type of Temperature Reference
To select the Reference between Internal and External, touch the REFERENCE
bar. When selecting External Reference, the Callendar-Van Dusen parameters must be
set. It is also necessary to choose if the External Probe is going to control the block or
not.
ID: Set an identification for the sensor
R0 (): The last resistance measurement in 0 °C of the sensor
A, B, C: Callendar-Van Dusen coefficients
Low (°C): Lower value of the reference sensor calibrated range
High (°C): Higher value of the reference sensor calibrated range
The coefficient values can be found in the Reference Sensor Certificate.
