Table A-3. L4451A DAC Voltage Calibration Points.

Calibration Point	Minimum	Maximum	Result
	Expected Value	Expected Value
1	-0.5V	0.5V
2	-10.0V	-8.0V
3	-10.5V	-8.5V
4	-11.0V	-9.0V
5	-11.5V	-9.5V
6	8.0V	10.0V
7	8.5 V	10.5V
8	9.0V	11.0V
9*	9.5V	11.5V

* Voltage calibration constants for the channel are saved in non-volatile memory after completion of this step.

Current Adjustments

1With the DMM disconnected from the L4451A, set the DMM to the 100mA range or the lowest range that can measure 20 mA (do not use autorange).

2The DMM reading is the current offset for the selected range. If the DMM has “null” capability, turn it on at this time. Otherwise, record the offset which will be subtracted from the subsequent current measurements.

3Unsecure the instrument for calibration using the command:

CALibration:SECure:STATe 0, <code>

4Connect channel 1 of the L4451A to the DMM as shown in Figure A- 1. Set the DMM to measure DC current.

5Refering to Table A- 4, set the first DAC calibration point on channel 1 using the command:

CALibration:BEGin:CURRent 1, (@<channel>)

For channel 1, the command is executed as:
