Table C-2 Command Summary (continued)
ID? Queries the identification (model number) of the supply. (see page 82).
IDATA < ch >, < Ilo > , < Ihi > Sends data to calibrate the current setting circuits of the specified output < ch >. Ilo and
Ihi are measured values which the supply uses to calculate correction constants (see
Appendix A).
IHI < ch > Causes the current of the specified output < ch > to go to the high calibration point (see
Appendix A).
ILO < ch > Causes the current of the specified output < ch > to go to the low calibration point (see
Appendix A).
IOUT? < ch > Queries the measured output current of the specified output < ch > (see page 73). The
response is a real number. The front panel display can be used to monitor the measured
output current (and voltage) of the selected output < ch >.
IRDAT < ch >, < Ilo >, < Ihi > Used to calibrate the + current readback for the specified output < ch >. This command
must be sent after IRHI and IRLO commands.
IRLO < ch > Finds the minimum + current readback value for the specified output < ch > ( see
Appendix A.)
IRHI < ch > Funds the maximum + current readback value for the specified output < ch > (see
Appendix A.)
IRLN <ch> Finds the minimum - current readback value for the specified output < ch > (see
Appendix A.)
IRHN <ch> Finds the maximum - current readback value for the specified output < ch > ( see
Appendix A).
IRSET < ch >, < x > Sets the full scale current range programming for an output < ch > . The power supply
will select the lowest operating range that will contain the value (x). If the present
operating current of the supply is greater than the full scale range selected, the present
output current will be reduced to the full scale value of the new range selected. If the
current entered is larger than the highest possible range, an error message will result.
IRSET? < ch > Queries the full scale current range setting of an output < ch > .
ISET < ch >,< x > Sets the current of the specified output < ch > (see page 73).
ISET? < ch > Queries the present current setting of the specified output < ch > (see page 73). The
response is a real number.
ISTEP < ch >,< x >
*
Increases or decreases an output < ch > current in steps. If the step value < x > is
positive, output current will increase by the step value, if the step value is negative, the
output current will decrease by the step value. Trying to step beyond the active operating
range will cause a number range error.
METER < ch > Selects which output < ch > of the supply the front panel will display.
METER? Returns which output the supply is displaying on the front panel.
