Miscellaneous calibration commands
Miscellaneous commands perform miscellaneous calibration functions such as programming
the calibration code and date. These commands are discussed in detail in the following
paragraphs.
:CODE (:CALibration:PROTected:CODE)
Purpose To program the calibration code or password so that you can perform the
calibration procedures.
Format :cal:prot:code '<char_string>'
Parameter Up to a 8-character string including letters and numbers.
Description The :CODE command enables the Model 2010 calibration procedures when
performing these procedures over the bus. In general, this command must be
sent to the unit before sending any other comprehensive or manufacturing
calibration command. The default calibration code is KI002010.
Note • The :CODE command should be sent only once before performing either
the comprehensive or factory calibration. Do not send :CODE before each
calibration step.
• To change the code, first send the present code, and then send the new
code.
• The code parameter must be enclosed in single quotes.
Example :CAL:PROT:CODE 'KI002010' Send default code of KI002010
:COUNt? (:CALibration:PROTected:COUNt?)
Purpose To determine how many times the Model 2010 has been calibrated.
Format :cal:prot:coun?
Response <n> Calibration count.
Description The :COUNt? command lets you determine how many times the Model 2010
has been calibrated.
Note Use the :COUNt? command to help you monitor for unauthorized calibration
procedures.
Example :CAL:PROT:COUN? Request number of times the unit has been
calibrated.
