TECHNICAL GUIDE
l Output voltage for the solar cell unit
Output voltage when the watch is placed at a distance of
5 cm under a fluorescent light of 15 to 20 watts
Checking procedure
1.
Connect the tester to the output terminal of the solar cell
unit as shown in the illustration at right.
2.
With the probes of the tester applied, place the solar cell
unit at a distance of 5 cm under a fluorescent light of 15
to 20 watts, exposing the solar cell side to the light, and
then measure the output voltage.
l Checking the recharging function
A conventional method of checking the recharging function is to check the difference of the rechargeable
battery voltage between before and after a recharge.
Checking procedure
1.
Apply the probes of the tester as shown in the illustration
at right to measure the voltage of the rechargeable battery
before recharge (initial voltage).
2.
Place the watch at a distance of 5 cm under a fluorescent
light of 15 to 20 watts, and charge it for 30 minutes.
Notes:
* Use a fluorescent light to charge the watch, as light
sources generating heat may cause damage to the
watch. To charge the watch efficiently, place it under
the center of the fluorescent tube.
* While charging the watch, make sure that the watch
temperature does not exceed 60 ºC.
