7 Operate the electronic load in short (input short) mode. Record the current
reading, (I
short
), by dividing the voltage reading on the DMM by the resistance
of the current monitoring resistor.
8 Take the difference between the current readings in step 6 and step 7 is the
load regulation current (I
load
– I
short
). Record the calculated value in the “Test
Record Forms” on page 74. The difference of the readings during the
immediate change should be within the specification limits.
CCline regulation
1 Turn off the power supply using the AC line switch.
2 Connect the power supply output with a DMM, an electronic load, and a
current shunt. See “Recommended test equipment” on page 54 for details.
3 Connect the AC power cord of the power supply to the AC power source.
4 Turn on the power supply using the AC line switch.
5 Program the output voltage and output current as described in the test record
form under CC line regulation.
6 Operate the electronic load in constant voltage mode and set its voltage to the
power supply output value as described in Table 2-10.
Check that the front panel CC annunciator of the power supply remains lit. If it
turns to CV or UNREG, adjust the load so that the output current drops slightly
until the CC annunciator lights up.
