Calibration Commands
See “Calibration Overview” starting on page 95 for an overview of the
calibration features of the multimeter. For a more detailed discussion
of the calibration procedures, see chapter 4 in the Service Guide.
CALibration?
Perform a calibration using the specified calibration value
(
CALibration:VALue command). Before you can calibrate the
multimeter, you must unsecure it by entering the correct security code.
CALibration:COUNt?
Query the multimeter to determine the number of times it has been
calibrated. Your multimeter was calibrated before it left the factory.
When you receive your multimeter, read the count to determine its
initial value. [Stored in non-volatile memory]
• The calibration count increments up to a maximum of 32,767 after
which it wraps-around to 0. Since the value increments by one for
each calibration point, a complete calibration will increase the value
by many counts.
CALibration:SECure:CODE < new code >
Enter a new security code. To change the security code, you must first
unsecure the multimeter using the old security code, and then enter a
new code. The calibration code may contain up to 12 characters.
[Stored in non-volatile memory]
CALibration:SECure:STATe {OFF|ON},< code >
Unsecure or secure the multimeter for calibration. The calibration code
may contain up to 12 characters. [Stored in non-volatile memory]
CALibration:SECure:STATe?
Query the secured state of the multimeter. Returns “0” ( OFF ) or “1” ( ON ).
