Calibration Count
You can determine the number of times that your power supply has been
calibrated. Your power supply was calibrated before it left the factory. When
you receive your power supply, read the count to determine its initial value.
The calibration count feature can be performed from the remote interface
only.
• The calibration count is stored in non-volatile memory, and does not
change when power has been off or after a remote interface reset.
• The calibration count increments up to a maximum of 32,767 after which
it wraps-around to 0. Since the value increments by one for each
calibration point, a complete calibration will increase the value by 6
counts.
• Remote Interface Operation:
CALibrate:COUNt?
Calibration Message
You can use the calibration message feature to record calibration
information about your power supply. For example, you can store such
information as the last calibration date, the next calibration due date, the
power supply's serial number, or even the name and phone number of the
person to contact for a new calibration.
You can record and read information in the calibration message from the
remote interface only.
• The power supply should be unsecured before sending a calibration
message.
• The calibration message may contain up to 40 characters.
• The calibration message is stored in non-volatile memory, and does not
change when power has been off or after a remote interface reset.
• Remote Interface Operation:
CALibrate:STRing

Store the cal message
The following command string shows how to store a calibration message.
