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 para-
graphs.
:CODE
(:CALibration:PROTected:CODE)
Purpose To program the calibration code or password so that you can perform the cal-
ibration 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 2015 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 KI002015.
NOTES The :CODE command should be sent only once before performing either the compre-
hensive or factory calibration. Do not send
:CODE before each calibration step.
To change the code, first send the present code, then send the new code.
The code parameter must be enclosed in single quotes.
Example :CAL:PROT:CODE 'KI002015' Send default code of KI002015.
:COUNt?
(:CALibration:PROTected:COUNt?)
Purpose To determine how many times the Model 2015 has been calibrated.
Format :cal:prot:coun?
Response <n> Calibration count.
Description The :COUNt? command allows you to determine how many times the
Model 2015 has been calibrated.
NOTE Use the :COUNt? command to help you monitor for unauthorized calibration
procedures.
Example :CAL:PROT:COUN? Request calibration count.
