Adjustment Procedures; Setting Up The Test Equipment - National Instruments PXI-4070 Manual

Adjustment Procedures

Note NI recommends repeating the verification procedures after you perform these
adjustment procedures. Reverification ensures that the device you have calibrated is
operating within specifications after adjustments.
If you skip any of the steps within a section of the adjustment procedures,
Caution
NI-DMM does not allow you to store your new calibration coefficients. Instead, NI-DMM
restores the original coefficients to the EEPROM.

Setting Up the Test Equipment

Note Ensure that the calibrator is warmed up for at least 30 minutes before you begin this
procedure.
NI PXI-4070 Calibration Procedure
This section explains how to adjust the NI 4070. You can choose to
perform these adjustment procedures with or without performing the
verification procedures first.
The parameters Range, Resolution, Expected Measurement, and
Frequency used in function calls in this section have floating point values.
For example, if Range =

If you have not already set up the test equipment, complete the following
steps:
1. Remove all connections from the four input banana connectors on the
NI 4070.
2. Verify that the calibrator has been calibrated within the time limits
specified in the Required Test Equipment
calibration has been performed within the last 30 days. Consult the
Fluke 5700A/5720A user documentation for instructions on
calibrating these devices.
3. Reset the calibrator.
4. If you have not already done so, allow the NI 4070 to warm up for
30 minutes within a powered-on PXI chassis.
