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 5 counts.
• Remote Interface Operation:
CAL:COUN? Query the number of times of calibration
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:
