User manual for digital clock SWZ-W610
7.3.4.
“Func” menu
This menu allows to set operation mode:
“dAtE”
- this parameter allows to switch on/off displaying of the date
“yEAr”
- this parameter allows to switch on/off displaying of the year while date is
showed
”oFF”
- displaying of the year is off
”on”
- displaying of the year is on
“thEr”
- this parameter allows to switch on/off displaying of the temperature. If
temperature sensor is not connected to the {
THERM
} input, or if it is damaged,
the signs „
- - - -
” will be displayed in place of current temperature.
7.3.5.
“dCF” menu
This menu contains parameters corresponding to cooperation with DCF77 module.
”modE”
- this parameter enables synchronization of internal clock with DCF77 signal, and
allows to define resting state of the module output. There are available values:
”oFF”
- synchronization is off
”L Lo”
- synchronization is on, the resting state of DCF module output is LOW
”L Hi”
- synchronization is on, the resting state of DCF module output is HIGH
If it is impossible to synchronize clock with DCF signal within 7 days (no signal, or
errors in received data) the double dot between hour and minutes will start to pulse
in asymmetrical mode (lighting time much shorter than time of dimming).
”diSP”
- this parameter allows to on/off the signalisation of DCF77 module output state by
LED ( digital point of the most right digit). Lighting LED means high state of DCF
output. This parameter can be set to:
”oFF”
- signalisation is off,
”on”
- signalisation is on.
”Sync”
- this submenu allows to check the time of the last synchronization, the number of
correct received frames and bits of DCF77 signal.
”
hours:minutes
seconds
”
- the time of last synchronization
”
day.month.
year
”
- the date of last synchronization,
”F NF”
- number of received frames, where NF is the number of
frames in range 0 to 3
”b NB”
- number of received bits, where NB is the number of bits
in range 0 to 59
The manner of presentation of these informations is showed in
Figure 7.1. The first
information after selection
”Sync”
(and pressing the
„ENTER”
button) is the time of last
synchronization (e.g. 23:25:00). Subsequent pressings the [
v
] button, cause in displaying of
another informations in showed order; the date of last synchronization (e.g. 19
th
of may 2005),
the number of correctly received frames (e.g. 2 frames) and the number of collected bits of
frame being received (e.g. 47 bits).
