Calibrate Commands
Parameter Typical Return
<"date">String program data. Enclose string
parameters in single or double quotes.
Date of last calibration
Enters the calibration date: CAL:DATE "12/12/12"
CALibrate:LEVel P1|P2|P3|P4
CALibrate:LEVel?
Advances to the next level in the calibration. P1 is the first level; P2 the second, P3 the third, and P4 the fourth.
Parameter Typical Return
P1|P2|P3|P4 (none)
Selects the first calibration point: CAL:LEV P1
l Some calibration sequences may require some settling time after sending CAL:LEV but before reading the data
from the DVM and sending CAL:DATA.
CALibrate:PASSword <password>
Sets a numeric password to prevent unauthorized calibration.
Parameter Typical Return
<password>a numeric value up to 15 digits (none)
Set a new password to a value of 1234: CAL:PASS 1234
l If the password is set to 0, password protection is removed and the ability to enter calibration mode is unrestricted.
The factory setting is 0 (zero).
l To change the password: unsecure calibration memory with old code, then set the new code.
l If you forget your password, refer to the calibration section.
l This setting is non-volatile; it will not be changed by power cycling or *RST.
CALibrate:SAVE
Saves the calibration constants in non-volatile memory. Do this at the end of the calibration to avoid losing changes.
Parameter Typical Return
(none) (none)
Store cal constants in non-volatile memory: CAL:SAVE
