CALIBRATION
CAUTION
Please refer to the power supply operation manual for further information before
performing calibration procedures. Only qualified personnel who deal with
attendant hazards in power supplies, are allowed to perform calibration procedures.
If calibration is not performed properly, functional problems could arise, requiring
that the supply be returned to the factory.
Introduction
The Asterion DC Multioutput Series power 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 operation
manual to find the required calibration interval. The Asterion DC Multioutput Series
power supply is calibrated for output voltage programming and output current
programming.
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:
•
Model HP 344401A or equivalent 6-digit digital voltmeter (DVM)
•
Current shunt rated for an accuracy of 0.05% or better and a minimum of 125% of
the UUT full scale output current
