On page 4-6, under 4.7.2, replace step 3 with:
3. Connect the LO output (black) with the Ground (green) input of the Analyzer.
Connect the HI output (red) with all current (BNC) inputs and the A/L1, B/L2, C/L3, and N
voltage banana inputs of the Analyzer. Refer to Figure 4.1.
On pages 4-8 & 4-9, under 4.8.1 replace steps 2 & 3 with:
2. To check the A/L1, B/L2, C/L3 inputs, connect the N input to Ground (See Figure 4-2). N now
will give zero reading.
3. To check the N input, connect the N input with the adjacent C/L3 input. A/L1, B/L2, C/L3 now
will give zero reading. Refer to Figure 4-3.
On page 4-10, under 4.8.2, replace steps 2 & 11 with:
2. To check the A/L1, B/L2, C/L3 inputs: connect the N input to Ground (See Figure 4-2).
11. Connect the N input with the C/L3 input (See Figure 4-3). A/L1, B/L2, C/L3 now give zero
reading.
On page 4-11, under 4.8.3, replace steps 2 & 11 with:
2. To check the A/L1, B/L2, C/L3 inputs: connect the N input to Ground (See Figure 4-2).
11. Connect the N input with the C/L3 input (See Figure 4-3). A/L1, B/L2, C/L3 now give zero
reading.
On page 4-13, under 4.8.4, replace steps 2 & 11 with:
2. To check the A/L1, B/L2, C/L3 inputs: connect the N input to Ground (See Figure 4-2).
11. Connect the N input with the C/L3 input (See Figure 4-3). A/L1, B/L2, C/L3 now give zero
reading.
On page 4-15, under 4.8.5, replace steps 1 & 10 with:
1. To check the A/L1, B/L2, C/L3 inputs: connect the N input to Ground (See Figure 4-2).
10. Connect the N input with the C/L3 input (See Figure 4-3). A/L1, B/L2, C/L3 now give zero
reading.
On page 4-17, under 4.9, replace step 3 with:
3. Short-circuit the four current inputs with a termination piece of 50 Ω or lower. Refer to Figure 4-4.
The 438 II model should now follow the 435 II steps in the verification and Adjust
procedures.
