5. To begin calibration with the external resistor, remove the DC
source and connect the precision resistor to the control card, as
shown in Figure 37(right) below.

6. The supply will display CH1 EXT. VOLT Res. Press to
calibrate.
7. Once finished, CH1 EXT. CURR Res will be selected. Connect
the precision resistor as shown in Figure 37(left). Press to
proceed with the calibration.
8. (Dual channel) The calibration process for the dual channel
DIO/Analog Interface Card is similar to the above steps for
single channel, with the exception of repeating steps 3-7 twice.
9. (Dual channel) For the external voltage calibration, connect the
leads like Figure 38 shown below.
