Calibration
Parameters Calibrated
The following parameters may be calibrated.
• External Current Monitor ( Imon )
• External Current Programming ( Iprog )
• Input Current
• Input Voltage
• Input Resistance
You do not have to do a complete calibration each time. If appropriate, you may calibrate only the current,
voltage or resistance and proceed to “Saving Calibration Constants”. However, Imon and Iprog must be
calibrated before Input Current is calibrated and both Imon and Input Current must be calibrated before Input
Resistance can be calibrated.
The following section lists calibration programs to re-calibrate ( adjust ) those specifications which are not
within specification. The programs listed are for use with either an HP Series 200/300 computer using HP Basic
( RMB ) or a PC equipped with an IEEE-488.2 interface card an HP Basic for Windows.
The variables to be used in the programs are listed in Table B-2 Variables. The connections for the test
equipment, current shunts and DVMs are shown in Figures B-1 for IMON ZERO calibration, B-2 for IMON,
IPROG and CURRENT calibration, B-3 for VOLTAGE calibration and B-4 for RESISTANCE calibration. A
listing of all programming commands and their explanations can be found in the Programming Guide, part
number 5964-8198.
