Section 4: Using the Model 9100: Resistance Function 4.7-3
Final Width = 215mm
4.7.3.1 Bottom Screen Keys
Ω Selects Resistance function. The default condition accepts Low
constant source currents with 4-wire connections.
Ω
Selects Conductance function. Refer to sub-section 4.8.
CHANGE Scales the analog circuitry to accept alternative constant source currents.
CURRENT Refer to paras 4.7.5.7.
4 WIRE Connects the analog circuitry as a 4-wire source when selected, and a
2-wire source when deselected. Default condition is 'selected'. The
screen key operates as toggle-on / toggle off.
Refer to paras 4.7.5.4 to 4.7.5.6.
∆ Accesses the 'Percentage Deviation' and 'Resistance Offset' displays to
add to the screen presentation. Refer to paras 4.7.3.3 and 4.7.4.1.
4.7.3.2 Right Side Screen Keys
A. Digit Edit Facility Keys operate on the value marked by the cursor.
X
10 Multiplies the marked value by ten.
÷10 Divides the marked value by ten.
ZERO Sets the marked value to zero.
± Inverts the polarity of the marked deviation or offset value.
B. Direct Edit Facility Right side keys operate on the value in the edit box, and
acting in place of the ↵ key, exit from Direct Edit back to
Digit Edit and set the value as evaluated in the box.
i. Output Value and Offset Value
Ω Evaluates the number in the box in Ohms.
kΩ Evaluates the number in the box in Kilohms.
MΩ Evaluates the number in the box in Megohms.
ii. Deviation Value
% Evaluates the number in the box in Percentage Deviation.
The Deviation value is limited to ±10% of the Output value.
Output and Offset values are set into the same resolution. All values are set into the
highest resolution available to their magnitude.
