unsecured and adjusted. If autocal is secured, the calibration number is
also incremented by 1 whenever an autocal is performed; if unsecured,
autocal does not affect the calibration number.
• The calibration number is stored in cal-protected memory and is not lost
when power is removed.
• The multimeter was adjusted before it left the factory which increments
the CALNUM. When you receive the multimeter, read the calibration
number to determine its initial value.
