TECHNICAL GUIDE
IV. VALUE CHECKING AND ADJUSTMENT
Current Consumption
For the whole module (in the WATCH mode) : Less than 2.5 µA (With 3.0 V. supplied from a battery)
<How to measure the current consumption>
1. Remove the lithium battery and connect the tester as illustrated below.
2. With the tester connected to the movement, reset the circuit.
(To reset the circuit, refer to "I. Remarks on Battery Change".)
3. When stable measurements can be obtained, read the measurement.
Functional Checks
After replacing module with a new one, Cal.DH33 requires checks for the accuracy of data such as 1: water
depth measurement, 2: pressure index value and 3: temperature measurement . Those checks should be
performed in the TEST mode.
In the Atmospheric pressure/Water depth mode, check the
accuracy of water depth measurement and water resistance
Functional check procedure
Go to the TEST mode
Close the case back
Check atomospheric pressure value
Check temeperature
Check if all the segments light up
Check if EL backlight light up
Check if the buzzer rings
Press Button D in the Buzzer mode to return to the
normal TIME/CALENDAR display and set the time.
