Cal. H024A
IV. VALUE CHECKING
1.3KΩ ~ 1.5KΩ
• Time accuracy
To measure the accuracy, light up all the segments. To do so, press buttons “C” and “D” at the same
time in the TIME/CALENDAR SETTING display.
After the measurement, press any one of the button “A”, “B”, “C” or “D” to return to the TIME/
CALENDAR display.
• Coil block resistance
140Ω ~ 200Ω
• Upconverter coil resistance
• Current consumption
For the whole movement : less than 3.76μA
For the circuit block alone : less than 1.3μA
Notes:
• Before measuring the current consumption, be sure to reset the circuit. Otherwise, current consumption
cannot be measured properly.
• When the current consumption for the whole movement exceeds the standard value, measure the
current consumption for the circuit block alone. If the result is within the standard value range of the
current consumption for the circuit block alone, overhaul and clean the movement parts and then
measure the current consumption for the whole movement again.
