2. Secondary coil resistance

CAUTION: If the resistance is extremely low, this indicates the presence of a short-circuit.

Specific Resistance:

[Primary side]

Between terminal No.1 and No.2
0.73 Ohms ± 10 %

Between terminal No.2 and No.4
0.73 K.Ohms ± 10 %

[secondary side]

Between (A) and (B)
12.8 K.Ohms ± 15 %

Between (C) and (D)
12.8 K.Ohms ± 15 %





3. Insulation between primary terminal and case: 10 M.Ohms or more.
