MODEL 1000N
Summary of Malfunctions:
• Control functions begin at over voltage level between two steps on the selector switch:
Leakage from (CR5), (Z4), and (CR6), towards (Z1).
• Adjustment of the short-circuit current: Transformer (T1) - (Z1) not operable.
• Impossible to obtain "0" on the M Ω and G Ω scales: The connecting layer has been cut at
(A101), (A103), or (Z5).
• Incorrect zero position for 1000 V / G Ω : The circuits are not clean, or there is insufficient
protection for selector rod circuits. No contact with small protective strip: (C103) is defective.
• Incorrect K Ω readings: (Z2).
• Incorrect voltage readings: (R212). Unsuitable power consumption levels for printed circuit
assembly (I = 100 A for 600 V point).
• Defective functioning of beeper: (Z8), (Q3), beeper.
• Battery light does not function: (Z2c), (CR9).
