Remote Calibration Procedures

Zero offset adjustments

Each time you perform a zero offset adjustment, the instrument stores a new
set of offset correction constants for measurement functions and ranges. The
instrument will sequence through all required functions and ranges
automatically and store new zero offset calibration constants.
C A U T I O N
Be sure to allow the instrument to warm up and stabilize for 2 hours before
performing the adjustments. Follow the steps outlined below. Review the "Test
Considerations" described in the U3606B Service Guide before beginning this
test.
1 Select the DC voltage measurement.
2 Calibrate the zero point for DC voltage
3 Start the calibration.
4 Select the 2-wire resistance measurement.
5 Calibrate the zero point for 2-wire resistance
6 Start the calibration.

Never turn off the instrument during zero offset adjustment. This may
cause ALL calibration memory to be lost.
