4. How do I perform a midpoint calibration check?
Midpoint Calibration Checks can be performed using the instrument's AutoCal
Feature (see Section 7.6) or by using the Control Inputs on the Rear Panel of
the instrument (see Section 6.8.2). The IZS Option is required in order to
perform a mid-point span check.
5. Why does the ENTR key sometimes disappear on the Front Panel Display?
During certain types of adjustments or configuration operations, the ENTR key
will disappear if you select a setting that is nonsensical (such as trying to set the

(such as selecting an iDAS Holdoff period of more than 20 minutes).

re-appear.
