Calibration Errors

 

 

The following errors indicate failures that may occur during a calibration.

 

 

Refer to the 34970A Service Guide for more information.

 

701

Cal: security disabled by jumper

 

 

The calibration security feature has been disabled with a jumper inside

 

 

the instrument. When applicable, this error will occur at power-on to

 

 

alert you that the instrument is unsecured.

 

702

Cal: secured

 

 

The instrument is secured against calibration.

 

703

Cal: invalid secure code

 

 

You have entered an invalid calibration security code. You must use the

 

 

same security code to unsecure the instrument that was used to secure it,

 

 

and vice versa. The security code may contain up to 12 alphanumeric

 

 

characters. The first character must be a letter, but the remaining

 

 

characters can be letters, numbers, or an underscore ( _ ). You do not have

 

 

to use all 12 characters but the first character must always be a letter.

 

 

The security code is set to “HP034970” when the instrument is shipped

 

 

from the factory.

 

704

Cal: secure code too long

 

 

The security code may contain up to 12 alphanumeric characters.

 

 

A security code was received which contained more than 12 characters.

 

705

Cal: aborted

 

 

A calibration in progress is aborted when you turn off the instrument or

6

 

send a bus Device Clear.

706

Cal: value out of range

 

 

 

The specified calibration value (CALibration:VALue) is not valid for

 

 

the present measurement function and range.

 

707

Cal: signal measurement out of range

 

 

The specified calibration value (CALibration:VALue) does not match

 

 

the signal applied to the instrument.

 

708

Cal: signal frequency out of range

 

 

The input signal frequency for an ac calibration does not match the

 

 

required input frequency for this calibration.

 

709

Cal: no cal for this function or range

 

 

You cannot perform calibrations for most ac current ranges, the 100 M

 

resistance range, and period.
