LSI LASTEM M-Log – User’s manual
34
give logical status = 1 In case of short circuit or 0 V
give logical status = 0 In case of opened contact or 4 V
The sensors with status output that produce voltage (i.e. they aren’t pure contacts “open/closed”)
but with variable voltage according to measured status, can be connected to M-Log through one
diode; in this way every connection is always the right one, apart from the output voltage (no
divider is required). The anode of diode must be placed on clamp F of terminal board’s entrance and
the cathode towards the sensor.
For long acquisition it’s advisable power on externally the datalogger.
5.2.5
Fast acquisition mode of the measures
For diagnostic purposes, M-Log is equipped with a function that allows the acquisition of all
sensors connected to its inputs at maximum speed (excluding the sensors connected to the serial
port or received through the radio).
In order to activate the fast acquisition mode press key
and
at the same time. In this
mode, the acquisition rate becomes 1 second every 10 measures and LED of the instrument will
show a particular flashing: 5 green quicly blinkings.
Please note that in this condition the instrument:
Acquires all sensors and recalculates all measures with minimum rate of 1 second every 10
measures;
Keeps switching powers used to power the sensors permanently on;
Uses up much more energy;
Produces elaborations at the programmed rate; uses a higher number of samples compared
to the normal conditions;
In this mode the green
Ok
LED blinks 5 times every 5 seconds.
In order to set the instrument back to its normal mode, switch it off and on again without however
pressing key
and
at the same time.
5.2.6
Activation of sensor control
Function valid only for M-Log with connectors (ELO009 model)
The instrument acquires the sensors rapidly thus using up little energy; hence increasing its
operative autonomy.
When enabled, this function will replace the normal acquisition process. Avoid setting a check that
is too frequent, especially in case of several fast rate measures. Do not use this function if you aim
at saving as much energy as possible. For example, in case you have programmed 8 measures with
10 seconds acquisition rate, set the Probe check rate to 1 minute or higher.
