5. Checking high voltage range, low voltage point. Press [ VOLT ] [ 3 ] [ Enter ]. Wait 10 seconds, then record actual
input voltage (DVM reading) and front panel readings on test record card under high voltage range, low voltage.
6. Checking high voltage range, high voltage point. Press [ VOLT] [select voltage from the following table] [Enter].
7. Wait 10 seconds, then record the actual input voltage (DVM reading) and front panel voltage reading on the test record
card under high voltage range, high voltage.
8. Checking low voltage range, low voltage point. Press [ VOLT ] [ 3 ] [ Enter ]. Press [ VOLT ]. Scroll until display
reads V:RANG, press [ 3 ] [ Enter ]. Press shift key then [ Sense ]. Scroll until display reads S:V:RNG, press [ 3 ]
[Enter]. Wait 10 seconds then record actual input voltage (DVM reading) and front panel readings on test record card
under low voltage range, low voltage.
9. Checking low voltage range, high voltage point. Press [ VOLT ] [ select voltage from following table ] [ Enter ].
10. Wait 10 seconds then record actual input voltage (DVM reading) and front panel readings on test record card under
low voltage range, low voltage.
CV Mode Regulation Test
This test verifies the Input Voltage remains within specification when the input current is changed from a low
current to rated current.
1. Connect Electronic Load, power source and DVM as shown in figure B-3. Be sure + sense and – sense are connected
to the +/- input terminals and the remote/local button is in the remote position.
2. Turn on the Electronic Load and press [ Recall ]. Scroll until display reads *RST and press [ Enter ].
3. Press [ Func ]. Scroll until display reads FUNC VOLT, then press [ Enter ].
4. Press [ Volt ] [ select voltage from following table ] [ Enter ].
5. Turn on power source. Set power source voltage and current to values listed in following table.

6. Wait 10 seconds and record input voltage reading.
7. Reset power source current level to value listed in following table.

8. Wait 10 seconds and record input voltage reading.
9. Subtract reading in step ‘8’ from reading in step ‘6’. Absolute value of difference should be less than specification.
