L4451A and L4452A Calibration Procedures A

L4452A Multifunction Module

Verification and calibration of the L4452A Multifunction Module is limited to channels 6 and 7 which are the DAC (voltage) output channels.

L4452A Verification

The test connection for verifying the DAC output voltage on channels 6 and 7 of the L4452A are shown in Figure A- 3.

DAC Output Verification Test

This procedure is used to check the calibration of the DAC outputs on channels 6 and 7 of the L4452A. Verification checks are performed only for those output values with unique calibration constants.

1With the DMM disconnected from the L4452A, set the DMM to the 100V range or the lowest range that can measure 16V (do not use autorange).

2Short the inputs to the DMM. The DMM reading is the offset voltage for the selected range. If the DMM has “null” capability, turn it on at
