2-16 Calibration
Setting calibration dates and saving calibration
At the end of the calibration procedure, the instrument will display the CALIBRATION
COMPLETE message. Press ENTER to continue, and the Model 2015 will prompt you to enter
the calibration date and the calibration due date. Set these dates as follows:
1. At the CAL DATE: mm/dd/yy prompt, use the left and right arrow keys, and the range
keys to set the calibration date, then press ENTER.
2. The unit will then prompt you to enter the next calibration due date with this prompt:
CAL NDUE: mm/dd/yy. Use the left and right arrow keys, and the range keys to set the
calibration due date, then press ENTER.
3. The unit will prompt you to save new calibration constants with this message: SAVE
CAL? YES. To save the new constants, press ENTER. If you do not want to save the
new constants, press the down range key to toggle to NO, then press ENTER.
NOTE Calibration constants calculated during the current calibration procedure will not be
saved unless you choose the YES option. Previous calibration constants will be
retained if you select NO.
Remote calibration
Follow the steps in this section to perform comprehensive procedures via remote. See Appen-
dix B for a detailed list and description of remote calibration commands.
When sending calibration commands, be sure that the Model 2015 completes each step before
sending the next command. You can do so either by observing the front panel CALIBRATING
message, or by detecting the completion of each step over the bus. (See Detecting calibration
step completion in Appendix B.)
The procedures for calibrating the Model 2015 via remote include:
• Preparing the Model 2015 for calibration
• Front panel short and open calibration
• DC volts calibration
• Resistance calibration
• DC current calibration
• AC volts calibration
• AC current calibration
• Distortion calibration
• Function generator calibration
• Programming calibration dates
• Saving calibration constants
• Locking out calibration
NOTE As with front panel calibration, you can choose to perform comprehensive, DC-only,
AC-only, distortion, or function generator calibration. Be sure to include a space
character between each command and parameter.
