The Channel Current Offset Calibration Registers store current offset
calibration constants in non-volatile memory. There are 16 registers, one
for each output channel. The register at base + 14016 stores channel 1,
base + 14216 stores channel 2, up to base 15E16 to store channel 16.
This register is non-volatile.

Current Offset Calibration Constant
Current Offset Calibration Constant: Writing a 16-bit value to this field
sets a new constant used to calibrate the channel output. Values are in the
range:
00016
80016
FFF16
Notes
maximum positive offset
nominal (zero) offset
maximum negative offset
Registers 0010016 through 001BE16 are located in non-volatile (FLASH)
memory. Writing to this memory requires a complicated sequence of
register accesses not documented here. It is recommended that calibration
be performed using the SCPI driver for the module, not register access.
Non-volatile memory has finite life, based upon the number of writes.
Use care when writing to this memory.
The contents of this register are loaded into volatile memory at power-on
and not used on an on-going basis.
