CR Mode Tests

These tests verify that the module operates in CR mode and the resistance programming is within specification. The programmed resistance values are checked by recording the voltage across the current monitor resistor and the input voltage (voltage at the modules + and – sense terminals ), then calculating the resistance as follows;

Load Resistance = Input Voltage / ( voltage across current monitor / monitor resistor value )

Resistance Range 1 Programming Accuracy

1.	Connect Electronic Load, Power source and DVM’s as shown in figure B-4. 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 till display reads *RST and press [ Enter ].
3.	Press [ Func ]. Scroll until display reads FUNC RES then press [ Enter ].
4.	Press [ RES ]. Scroll until display reads RES:RANG, press [ 1 ] then [ Enter ].
5.	Turn on the power source. See power source voltage and current values as listed in following table.

		N3302A	N3303A	N3304A	N3305A		N3306A
	Power Source Voltage Setting	24V	48V	12V	30V		15V
	Power Source Current Setting	7A	7A	10A	10A		20A
6.	Wait 30 seconds. Checking resistance range 1, high resistance point. Calculate and record resistance on test card.
	Input resistance = Input Voltage / ( DVM voltage reading from current shunt/ current shunt resistance).
7.	Checking resistance range 1, low resistance point. Reset power source voltage to following values.

		N3302A	N3303A	N3304A	N3305A		N3306A
	Power Source Voltage Setting	4V	6V	10V	5V		6V
	Power Source Current Setting	25A	10A	30A	50A		70A

8.	Press [ RES ] [ select resistance from following table ] [ Enter ].

	N3302A	N3303A	N3304A	N3305A	N3306A
	0.2Ω	1.2 Ω	0.5 Ω	0.125 Ω	0.100 Ω
9.	Wait 30 seconds. Calculate and record resistance range 1, low resistance point.
Resistance Range 2 Programming Accuracy
1.	Press [ RES ]. Scroll until display reads RES:RANG, For models N3302A, N3304A, N3305A and N3306A press
	[ 9 ] then [ Enter ]. For model N3303A Press [ 5 ] [ 0 ] then [ Enter ].
2.	Checking resistance range 2, low resistance point. Press [ RES ] [select resistance from following table ] [ Enter ].

	N3302A	N3303A	N3304A	N3305A	N3306A
	3.6 Ω	44 Ω	1.8 Ω	4.5 Ω	0.9 Ω

3. Set power source voltage and current values as listed in following table.

		N3302A	N3303A	N3304A	N3305A	N3306A
	Power Source Voltage Setting	20V	96V	6V	30V	6V
	Power Source Current Setting	7A	3A	7A	15A	8A

4.	Wait 15 seconds. Calculate and record resistance range 2 low resistance point.
5.	Checking resistance range 2, high resistance point. Press [ RES ] [select resistance from following table ] [ Enter ].

	N3302A	N3303A	N3304A	N3305A	N3306A
	40 Ω	480 Ω	20 Ω	50 Ω	10 Ω
