IV. VALUE CHECKING
• Coil block resistance
Coil block : 2.8 kΩ ~ 3.5 kΩ
Coil block for diving time hand : 2.8 kΩ ~ 3.5 kΩ
Coil block for alarm: 1.1 kΩ ~ 1.7 kΩ
Coil block for 1/10 m depth hand : 1.1 kΩ ~ 1.7 kΩ
• Current consumption
For the whole movement : less than 1.6 µA (with voltage supplied from a battery)
For the circuit block alone : less than 1.4 µA (with voltage supplied from a battery)
• Before measuring the current consumption, be sure to reset the circuit with the tester connected.
To reset the circuit, refer to "II. REMARKS ON INSTALLING THE BATTERY".
• When measuring the current consumption, do not touch the water contact sensor with fingers or short-circuit it.
(If the water contact sensor is short-circuited, the diving function may be activated and increase the cur-
rent consumption. As a result, correct measurement cannot be obtained)
• Time accuracy
When measuring the accuracy, pull out the crown to the first click and set the gate of the quartz tester to "10".
