The wrong line frequency setting will cause reading errors to occur.

CALibration

 

The CALibration command subsystem allows you to enter a security code to prevent

 

accidental or unauthorized calibrations of the multimeter. When you first receive your

 

multimeter, it is secured. You must unsecure it by entering the correct security code

 

before you can calibrate the multimeter (see CALibration:SECure:STATe command).

:COUNt?

CALibration:COUNt? queries the multimeter to determine the number of times a point calibration has occurred. A complete calibration of the multimeter increases the count by the number of points calibrated. It is not a record of complete calibrations. The count is stored in non-volatile memory.

Comments *RST does not change the calibration count stored in non-volatile memory.

Example Query the Number of Occurrences of Point Calibrations

CAL:COUN?

Query the calibration count.

:LFRequency

CALibration:LFRequency 5060400 sets the line frequency to either 50Hz or 60Hz.

Comments

You must execute the CAL:LFR command with a parameter of 50 or 400 to change the line frequency setting to 50Hz. Specifying 400Hz sets line frequency to 50Hz since 400 is an even multiple of 50.

Default Setting: 60Hz

*RST does not change the line frequency setting.

Example Set the Line Frequency to 50Hz

CAL:LFR 50

Change the line frequency.
