Remote calibration overview
The steps below outline the general procedure for calibrating the Model 6485 using
remote commands. Refer to “
” for details on calibration steps, calibration
points, and test equipment connections.
1.
Send the following command to unlock calibration:
:CAL:PROT:CODE 'KI006485'
Note that the above command uses the factory default code.
2.
Perform voltage offset correction by sending the following command:
:CAL:UNPR:VOFF
Be sure a BNC shielding cap is connected to the INPUT jack before sending the
above command.
3.
Send the appropriate command to select the range to be calibrated. For example,
the following command selects the 20mA range:
:SENS:CURR:RANG 2e-2
4.
Make appropriate connections, then send the commands for each calibration point
for the selected function and range. For example, send the following commands for
the 20mA range:
:CAL:PROT:SENS 0
:CAL:PROT:SENS 2e-2
:CAL:PROT:SENS –2e-2
NOTE
Be sure the appropriate calibration signal is applied to the INPUT jack before
sending the command for each calibration point. See “
5.
Repeat steps 3 and 4 for each range (
6.
After all ranges are calibrated, send the commands to program the calibration
dates; for example:
:CAL:PROT:DATE 2001,12,15
:CAL:PROT:NDUE 2002,12,15
7.
Finally, send the following commands to save calibration constants and then lock
out calibration:
:CAL:PROT:SAVE
:CAL:PROT:LOCK
