When doing this, make a note of foreign bodies and damaged gears.
Bridges (2) and (3) must be seated firmly so that all the indicator adjustment
gears engage properly.
Checking coil
resistance
Connect a measuring devices to points (B) and (C).
The measured value must not exceed 1.5 to 2 KΩ.
Replace the mechanism if the resistance value is outside tolerances.
Checking mechanism
function
Push the clock hands and second hand down onto point (A).
Replace the mechanism completely if time differences are outside permissible
tolerances.
For tolerances please refer to the TPH, TU00.1308.01 000 01, Section 3, Chapter 8.
