The value in Volt of the ba ery level will be displayed. With a fully charged ba ery
you will have 4.2 V while at low ba ery the value will be below 3.5 V. Press SET to
exit this func on and to return to the measurement.
6.10 Datalogger management - only for instrument version with data logger func onality
The data logger can store up to 130,000 measurement points (65,000 if also the
temperature is stored) in steps ranging from 1 sec. to 10 hours according to
the parameter , defined in the Parameters menu. Cycle length is determined
t1
by the parameter , defined in the Parameters menu.
t2
Data stored during the last Datalogging are permanently saved in nonvola le memory whithin the
instrument, so that the measures will always be accessible un l the crea on of a new cycle of
datalogging.
It is possible to create up to 5 par al cycles inside the datalogger memory. At each command to
start a Datalogger cycle, the operator is asked to select if he wants to start a new datalogger cycle
or to con nue a previous one.

It is very important any way that all sub-cycle will be created with the same
se ng. In par cular with the same parameter and the same se ng for the

temperature ton / toff.
For long datalogging cycle it is possible to save the ba ery discharge using the Standby func on of
the instrument. This func on is automa cally enabled when the acquisi on me between 2 points
is longer than the AUTO-POWER OFF me.
Example:
AUTO POWER OFF me (Parameter
) = 1 minute
OFFXX
Acquisi on me (Parameter )
= 5 minutes
t1
In this condi on, between 2 acquisi on points, the instrument turns off the display and all other
func onality. It wakes up 30 seconds before to toake a point and for the next 5 seconds.
The AUTO-POWER-OFF func on is not ac ve during a datalog cycle.
If during a datalog cycle a low ba ery condi on is detected, the cycle is stopped.
All points acquired un l that moment are saved in the internal nonvola le memory.
For long datalog cycle, the internal ba ery of the instrument is not sufficient. In
this case it is necessary to keep the instrument power supplied via the USB port.
