25 ohm, 100 ohm and 10,000 ohm. In addition, an external reference resistor
connected to Rs1, Rs2, CH2 or CH4 can be selected.
Sensing Current
Sensing Current the sensing current used with the channel and probe. Possible
values depend on the reference resistor selected.
•
1 ohm and 10 ohm internal reference can have the sensing current set to
any value between 0.0001 and 20.0 mA
•
25 ohm internal reference can have the sensing current set to any value
between 0.0001 and 10.0 mA
•
100 ohm internal reference can have the sensing current set to any value
between 0.0001 and 5.0 mA
•
10,000 ohm internal reference can have the sensing current set to any
value between 0.0001 and 0.1 mA
•
The external reference can have the sensing current set to any value be
-
tween 0.0001 and 20.0 mA
The sensing current is also limited by the probe's or reference resistor's maxi-
mum current value.
Use the Standby Current drop-down list to select whether the standby current is
enabled (On) or disabled (Off) for the selected channel.
Use the Calculation drop-down list to determine the type of measurement cal-
culation that is performed for the selected channel. Possible options are Ratio,
Resistance and Temperature.
The Temperature option is not available if any of the following are true:
•
The probe assignment for the selected channel is Undefined
•
The probe conversion type is set to None
•
The probe type is set to Resistor
•
The reference resistor is set to Variable Resistance
The Resistance option is not available if the reference resistor is set to Variable
Resistance.
If the selected reference is an external resistor, the Rs Input Settings button is
enabled. Click the Rs Input Settings button to display the dialog for the refer
-
ence channel. Otherwise, the Rs Input Settings button is disabled.
