SECTION 4
CALIBRATION
WARNING
Please refer to the power supply manual for further information before performing
calibration procedures. Qualified personnel who appropriately deal with attendant
hazards must perform calibration. If calibration is not performed properly,
functional problems could arise, requiring that the supply be returned to the
factory.
4.1 I
NTRODUCTION
The supply is calibrated to adjust internal signal levels to correspond to the expected
supply output signal levels. You must perform the calibration procedures if the power
supply’s programming or readback performance falls out of specification due to
component aging drifts. Refer to your power supply manual to find the required
calibration interval. The supply also is calibrated for output voltage programming,
output current programming, output overvoltage protection programming, voltage
readback, and current readback. There are 10 calibration factors (four measurement
and six output).
The calibration procedures in the following sections are designed to be performed at
ambient temperature of 25
°C + 5°C, after the unit has had a stable output and a stable
load for at least 30 minutes.
The following test equipment is required in addition to the computer system to
complete the following calibration:
•
6-digit digital voltmeter (DVM)
•
current shunt rated for 110% of full output current
