Closed - Case Electronic Calibration

The instruments features closed- case electronic calibration. No internal
mechanical adjustments are required. The instrument calculates correction
factors based upon the input reference value you set. The new correction
factors are stored in non- volatile memory until the next calibration
adjustment is performed. Non - volatile EEPROM calibration memory does
not change when power has been off or after a remote interface reset

Agilent Technologies Calibration Services

When your instrument is due for calibration, contact your local Agilent
Service Center for a low- cost recalibration. The 34405A is supported on
automated calibration systems, which allow Agilent to provide this service
at competitive prices.

Calibration Interval

A 1- year interval is adequate for most applications. Accuracy
specifications are warranted only if adjustment is made at regular
calibration intervals. Accuracy specifications are not warranted beyond the
1- year calibration interval. Agilent does not recommend extending
calibration intervals beyond 2 years for any application.
