Option IO-3 Calibration
Option IO-3 calibration should be performed
only after the 2301 has been completely
calibrated. The IO-3 may be calibrated in any
volts and any current range desired, provided
that the user provides full scale voltage and
current for those ranges (i.e. 600V on the
600V range). In the following procedure the
150V/1A ranges and inputs are used.
Connect the inputs as shown in Figure 8-7 and
select the 150V and 1A ranges. A DVM with
at least .03% DC accuracy is used to
monitor the outputs of Option IO-3.
