TECHNICAL GUIDE Cal. 6A32A VALUE CHECKING ● Coil block resistance 1.28 - 1.48kW [Measuring the coil block resistance] 1. Measure the resistance with the coil block installed on the main plate. 2. Apply the red and black probes of the tester to the patterns of the coil lead terminal. While doing so, take care not to touch the end portion of the coil lead terminal, as this may break the coil wire. ● Current consumption For the whole movement: less than 1.61mA For the circuit block alone: less than 0.3 mA [Measuring the current consumption for the whole movement] 1. Apply the red probe of the tester to the pattern of the positive (+) terminal of the circuit block and the black probe of the tester to the pattern of the negative (-) terminal of the coil block. 2. After connecting the tester, wait for approximately one minute until the current consumption becomes stable. When the current consumption shows stable measurements, read the measurement. [Measuring the current consumption for the circuit block alone] 1. Connect the tester to the positive (+) and negative (-) input terminals of the circuit block. Wait for approximately one minute until the current consumption becomes stable. When the currency consumption shows stable measurements, read the measurement. * Light may increase the current consumption, resulting in an inaccurate measurement. Protect the movement from light with a black cloth or similar, and take a measurement again. C-MOS-I Crystal unit Positive (+) Negative (-) CAUTION When the current consumption for the whole movement exceeds the standard value, measure the current consumption for the circuit block alone. If the current consumption for the circuit block alone is within the standard value range, a driving pulse may be generated. In that case, overhaul and clean the movement parts, and then measure the current consumption for the whole movement again. ● Checking the accuracy In order to check the accuracy, set the gate time of the quartz tester to 10 seconds, and measure the accuracy with the crown at the original position. 15
