7. Verification
7.1 Introduction
This chapter contains test procedures for checking the operation and specification of Chroma
63600 Series. The tests are performed using the 63600 Series models and some required
equipment. The required test equipment is listed in Table 7-1. Please refer the Performance
Tests section for equipment connecting and test procedure. The user can use verification
tables included at Verification Test Records section for checking the specification. The
performance tests confirm Chroma 63600 Series meet the published specifications. For the
detailed information of operation and programming please refer to the
Chapter 1, Chapter 1
and Chapter 1.
If any of the 63600 Series models requires service, refer to the list of Chroma Sales and
Support Offices at the web site
http://www.chromaate.com/english/contact/default.asp . The
calibration period suggested for this series of models is every 1 year.

7.3 Performance Tests
7.3.1 CC Mode Verification
This test verifies if the current programming and readings displayed on the front panel are
within specifications when the module is operating in CC mode. For each DMM reading, the
front panel display of current should be identical.
The reading of the Load in amps = Shunt current
±
inaccuracy.
DMM (V): means DMM dc voltage of voltage measurement
DMM (I): means DMM dc voltage of current shunt measurement
