Test 3 - This is a measurement of the insulation between the transformer high

voltage winding and the low voltage winding. Connections are exactly the same

as for Test 1 and 2. Test mode is UST-R.

NOTE: Once Tests 1, 2 and 3 are completed, Line 4 will populate with values

calculated by subtracting Test 2 from Test 1. This is applicable for

values of capacitance, current and watts. Line 4 is a calculated

comparison to the direct measurements of Test 3. Values on these two

lines should be essentially the same. If they are not, re-check all

connections and verify the proper operation of the test set. If Test 3 and

Line 4 vary by more than 2%, the Insulation Rating (IR) will

automatically populate with B (Bad).

Test 5 - This is a measurement of the insulation between the transformer low

voltage winding and the transformer tank, plus the insulation between the low

voltage winding and the tertiary winding, both measured in parallel. Connect the

HV cable to the low side (L) winding, connect the Red lead to the H winding and

Blue lead to the T (tertiary) winding.. Test mode is GSTg-R.

Test 6 - This is a measurement of the insulation between the transformer low

voltage winding and the transformer tank. Connections are exactly the same as

for Test 5. Test mode is GSTg-RB.

Test 7 - This is a measurement of the insulation between the transformer low

voltage winding and the high voltage winding. Connections are exactly the same

as for Test 5 and 6. Test mode is UST-B.

NOTE: Once Tests 5, 6 and 7 are completed, Line 8 will populate with values

calculated by subtracting Test 6 from Test 5. This is applicable for

values of capacitance, current and watts. Line 8 is a calculated

comparison to the direct measurements of Test 7. Values on these two

lines should be essentially the same. If they are not, re-check all

connections and verify the proper operation of the test set. If Test 7 and

Line 8 vary by more than 2%, the Insulation Rating (IR) will

automatically populate with B (Bad).

Test 9 - This is a measurement of the insulation between the transformer tertiary

winding (T) and the transformer tank, plus the insulation between the tertiary

winding (T) and high voltage winding (H), both measured in parallel. Connect

the HV cable to tertiary winding (T), connect the Red lead to the L winding and

Blue lead to the L winding.. Test mode is GSTg-B.

Test 10 - This is a measurement of the insulation between the transformer

tertiary winding and the transformer tank. Connections are exactly the same as

for Test 5. Test mode is GSTg-RB.
