Section 4. Calibration
Introduction
Adjustments to programming and readback accuracy for the power supply are made
using cover-on procedures. For safety, follow these instructions carefully.
Calibration Setup
Service
Environment
and
Precautions
•
Follow established antistatic procedures.
•
Work at a bench with adequate room and support for the unit under test and for
all equipment required.
•
To reduce shock hazard, use only an insulated, straight-blade screwdriver when
calibrating trim potentiometers.
•
NEVER calibrate these units alone. Ensure that someone is present who can help
should an accident occur.
Calibration on both the A1 and A2 assemblies is accomplished using multiturn
trimpots.
Table 4.1
below gives the circuit designation of the trimpot and the
parameter affected by that part. Calibration is performed at the factory during testing
and recalibration should be unnecessary unless major repairs are required.
Calibration should be done with the cover on through the access holes in the cover.
See
Figure 4.1
.
WARNING
Exercise caution when using and calibrating a power supply. High energy levels
can be stored at the output voltage terminals on a power supply in normal
operation. In addition, potentially lethal voltages exist in the power circuit and on
the output and sense connectors of a power supply with a rated output greater
than 40 V. Filter capacitors store potentially dangerous energy for some time
after power is removed.
WARNING
Use a non-conducting, straight-blade screwdriver to adjust the trim pots.
