Diode Silicon
Use the s or t key to cycle through the sensor types shown in Table 4-1, with “Silicon,” and
“GaAlAs” being the choices. Press the
Enter key. Proceed to Paragraph 4.5.1 to select a temperature
curve or press the
Escape key to return to the normal display.
4.4.2 Platinum Resistor Sensor Input Setup
Platinum type supports the various PTC RTD sensors detailed in Tables 1-2 and 4-1. Input range for
sensors is fixed by selection of type. Refer to table 4-1 for details on input range value for the three
PTC RTD ranges. All ranges use a sensor excitation current of 1 mA.
To setup a Platinum sensor input, press the Input Setup key. The first screen appear as follows.

4.4.3 NTC RTD Sensor Input Setup
NTC RTD type supports the various NTC RTD sensors (e.g., Cernox™, Rox
TM
, Thermox
TM
) detailed
in Tables 1-2 and 4-1. Resistance range for this type may be fixed to a single range or selected
automatically using the auto range feature. Auto Range will switch to the next higher range when the
sensor reading reaches 90% of the full scale value of the present range and will switch to the next
lower range when the reading falls below 8% of the full scale value. Refer to table 4-1 for details on
input range value for the four NTC RTD ranges.
To setup a NTC RTD sensor input, press the Input Setup key. The first screen appear as follows.
Select With °®
Input Setup Input A
Use the s or t key to toggle between Input A and B. Press the Enter key.
