Calibration Security
3. Apply a temporary short between pin 1 and pin 6 of the header on the main board, shown below.
4. Attach power and turn on instrument.
Be careful not to touch the power line connections or high voltages on the power supply module.
Power is present even if the instrument is turned off.
5. The error queue will show the message "Calibration security has been disabled."
Calibration security is unlocked, with password is reset to its factory default value. Calibration count is incremented
because jumper was connected during power-up, and error message +701,"Calibration error; security
defeated by hardware jumper" is issued. Nonvolatile calibration storage is updated to reflect these operations.
6. Turn off the instrument, remove temporary short, and remove power cord.
7. Reassemble instrument.
8. Enter a new security code as described above, and record the security code in a safe location.
