Section 7. Measurement Instructions
ExciteI ( IxChan, IxuA, Delay )
This instruction sets the specified switched current excitation channel to the
current specified.
Parameter
& Data Type
Enter
IxChan
Enter the current excitation channel to use for the first measurement. If the Reps
parameter is greater than 1, the excitation channel used for subsequent measurements will
be incremented with each measurement based on the MeasPEx parameter.

Result
IX1 7 Current excitation channel 1.
IX2 8 Current excitation channel 2.
IX3 9 Current excitation channel 3.
Ixu
Constant
The current excitation, in microAmps, to apply to the excitation channel. The allowable
range is ±2500 microAmps.
Delay
Constant
Variable or
Expression
Specifies the length of time the current excitation channel is enabled, after which, the
channel is set low and the datalogger moves on to the next instruction. If the Delay is set
to 0, the current channel will be enabled and the current will be held until the end of the
program scan or until another instruction sets a voltage, CAO, or current channel high.
This instruction must NOT be placed inside a conditional
statement.
NOTE
ExciteV (ExChan, ExmV, XDelay)
This instruction sets the specified switched voltage excitation channel to the
voltage specified.
Parameter
& Data Type
Enter
ExChan
Enter the excitation channel number to excite the first measurement.

Result
VX1 1 Switched excitation channels, are switched to the excitation
VX2 2 voltage for the measurement and switched off between
VX3 3 measurements
VX4 4
ExmV
Constant
The excitation voltage in millivolts. Allowable range ± 5000 mV.
XDelay
Constant
Variable or
Expression
Specifies the length of time the excitation is enabled, after which, the channel is set low
and the datalogger moves on to the next instruction. If XDelay is set to 0, the excitation
will be on until the end of the program scan or until another instruction sets an excitation
voltage.
