source same as the setting value for testing model before, and waited for 30 seconds,
record the voltage that passes through the load input terminals DMM (V) and the shunt
current reading DMM (I). Calculate the values of the resistance via DMM (V)/DMM (I).
Check the values to fit the specification.

7.3.3 CV Mode Verification
This test verifies if the voltage programming and reading value on the front panel display are
within specifications when the module is operating in CV mode. For each DMM (V) reading,
the front panel display of voltage should be equivalent to:
Load module reading in volts = DMM (V) reading in volts ± inaccuracy.
7.3.3.1 Checking High Voltage Range
A.
Connect the Load module, DC source, DMM and current shunt as Figure 7-1 shows.
Use DMM (V) to measure the voltage passing through the module's input terminal. Be
careful in making connections so that contact resistance voltage drop will not affect the
readings.
