4. Turn on the power source. Set the power source voltage and current to the values listed in the following table.
N3302A N3303A N3304A N3305A N3306A
Power Source Voltage Setting 61V 246V 61V 152V 61V
Power Source Current Setting 2A 0.6A 3A 2A 3A
5. Checking high voltage range, high voltage point. Wait 10 seconds then record actual input voltage and front panel
voltage reading on test record card under high voltage range, high voltage.
6. Checking high voltage range, low voltage point. Press [ VOLT ] [ 3 ] [ Enter ]. Wait 10 seconds, then record actual
input voltage and front panel readings on test record card under high voltage range, low voltage.
7. Checking low voltage range, low voltage point. Press [ VOLT ]. Scroll until display reads V:RANG Press [ 1 ] [
Enter ]. Press shift key then [ Sense ] scroll till display reads S:V:RNG, press [ 3 ]. Wait 10 seconds then record actual
input voltage and front panel readings on test record card under low voltage range, low voltage.
8. Checking low voltage range, high voltage point. Press [ VOLT ] [ select voltage from following table ] [ Enter ].
N3302A N3303A N3304A N3305A N3306A
6V 24V 6V 15V 6V
9. Wait 10 seconds then record actual input voltage 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 ].
N3302A N3303A N3304A N3305A N3306A
5V 25V 5V 8.3V 5V
5. Turn on power source. Set power source voltage and current to values listed in following table.
N3302A N3303A N3304A N3305A N3306A
Power Source Voltage Setting 6V 30V 6.5V 10V 6.6V
Power Source Current Setting 1A 0.4A 1A 1A 1A
6. Wait 10 seconds and record input voltage reading.
7. Reset power source current level to value listed in following table.
N3302A N3303A N3304A N3305A N3306A
Power Source Current Setting 30A 10A 60A 60A 120A
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 then specification.
