Section 4: Using the Model 9100: RTD Temperature Function 4.15-3
Final Width = 215mm
4.15.3.1 Bottom Screen Keys
THERMO
COUPLE
Selects K-Type function when RTD function is active.
RTD
TYPE
Permits selection of other conformance curves (paras 415.3.3).
CHANGE Scales the analog circuitry to accept alternative constant source currents
CURRENT (refer to paras 4.15.4.7).
4 WIRE Connects the analog circuitry as a 4-wire source when selected.
(refer to paras 4.15.4.5/6 — 4-Wire is the default).
TEMP Selects the type of temperature scale: IPTS-68 or ITS-90 when
SCALE the RTD function is active (paras 4.15.3.4).
4.15.3.2 Right Side Screen Keys
A. Digit Edit Facility Keys operate on the temperature value.
X
10 Multiplies the temperature value by ten.
÷10 Divides the temperature value by ten.
± Reverses the polarity of the temperature value (only available when °C or
°F has been selected).
°C Converts the temperature value into degrees Celsius (only available when
°F or K is active — the '°C' screen key label disappears when °C is active).
°F Converts the temperature value into degrees Fahrenheit (only available
when °C or K is active — the '°F' screen key label disappears when °F is
active).
K Converts the temperature value into Kelvins (only available when °C or °F
is active — the 'K' screen key label disappears when K is active).
B. Direct Edit Facility Keys operate on the number in the edit box, and acting in
place of the ↵ key, exit from Direct Edit back to Digit Edit,
setting the temperature value as evaluated in the box.
Temperature
°C Evaluates the number in the box in degrees Celsius.
°F Evaluates the number in the box in degrees Fahrenheit.
K Evaluates the number in the box in Kelvins.
All temperature values have the same resolution:
6 significant digits with 2 places of decimals.
