Calibration
Resistor Value
Registers
The Calibration Resistor Value Registers store the value of the resistor used
to calibrate current output. The Calibration resistor value is a 32-bit value
and requires two 16-bit registers. These registers are non-volatile.

Value: The 32-bit resistor value (in ohms) is written to two adjacent 16-bit
registers. The value is a float 32 format.
Voltage Calibration
Status Register
The Voltage Calibration Status Register provides a non-volatile record of
the voltage calibration status for each channel. This register is non-volatile.

WRITE
Ch XX Cal Stat: This field is set to a one (1) when the channel has been
successfully voltage calibrated. This field is set to a zero (0) when the
channel is not voltage calibrated.
Notes This register is not set or used by the hardware. The HP E1418A SCPI
driver, if used to calibrate the module, automatically sets the bits in this
register. If you use register programming to calibrate this module, you may
wish to use this register to record the calibration status.
The Voltage Calibration Status Register, the Current Calibration Status
Register, the Calibration Isolation Status Register, and the Calibration Card
Configuration Register are used together to store the overall calibration
status of the module.
