NOTE:
The unit cannot be turned off if it is logging. Logging must be stopped (see
below) before the unit can be switched off.
Log Button:
Pressing and holding the ‘log’ button starts the logging process. The button must be
held down until the ‘logging’ L.E.D stops flashing, and then released.
Logging mode is confirmed by the ‘logging’ L.E.D flashing every few seconds.
The logging process is terminated by pressing and holding the ‘log’ button until the
‘logging’ L.E.D stops flashing.
Logging indicator:
This L.E.D flashes every few seconds to indicate that logging is in progress.
Channel indicators:
These L.E.Ds flash ‘on’ when a pulse is detected.
Charge indicator:
This L.E.D illuminates when the unit is connected to a power supply and the battery
is charging. It will extinguish when the battery is fully charged or the charger is
disconnected.
USB Socket:
The USB connection provides the charger input and PC interface, using the supplied
cable.
The
SPC
Pulse
has a internal high capacity lithium ion battery which will provide up
to six weeks data logging. Indefinite logging is possible if the unit is connected to the
power supply provided in the kit. If the battery condition is unknown, or charge level
is low, it is recommended that the external power supply is used. To charge the
battery fully prior to using the logger, it should be connected to the power supply
and switched off for a period of 12-24 hours.
The
SPC
Pulse
may be utilised to a standard pulse logger, or, by toggling into ‘detect’
mode, as an intelligent unit.
In standard mode, the logger does not attempt to detect the polarity (if any) of the
pulse output. Volt-free mechanical or electromechanical contacts are not polarised
but electronic outputs usually are. For pulses to be reliably detected on electronic
contacts it is essential that the correct polarity is observed.
