The maximum number which can be entered is 250.
PB6100: the selectable steps are 100 usec,1 msec, 10 msec., 100 msec or 1 second.
For each channel an interval time can be entered. This interval time must be a
multiply of the selected step. The maximum interval time is 65000 x selected step
To start the measurement, select 'cyclic log' or 'log & fill RAM' on the datalog line. In 'log &
fill RAM' mode, the device will measure until the available RAM is full. In 'cyclic log' mode,
the device will continue measuring until stopped manually, overwriting old measurement
data when the buffer is full. The percentage on the left side of the display shows the current
usage of the buffer.
The buffer can contain up to about 29500 for the PB6000 and 500000 for the PB6100
measurement values. Due to bookkeeping overhead, this total amount will be lower when
the interval times are higher (ie. for slower measurements).
PB6000: If you attempt to start a new measurement while there is still data in the buffer, the
message 'Clear buffer first!' will be displayed and the measurement will not start.
Use the 'clear buffer' function to remove the previous measurement, or transfer it
to a PC first.
If the configured measurement speed can not be matched, a message 'Datalog speed too
high!' will be displayed and the measurement will not start.
PB6000: The device can perform up to 100 measurements per second.
PB6100: The device can perform up to `10000 measurement per second.
Up to 20000 measurement per second can be achieved when all the channel
intervals are the same. This setting can only be done using a PC with the
appropriated software.
It is possible to filter the storage of measurement values based on digital inputs or trips.
When the Logfilter option is set to a digital input, logging will only be performed when the
input is activated. The display shows 'armed' while logging is active without the input being
active (no measurement values are stored), and 'logging' when the input is active.
When the Logfilter option is set to an active trip on a channel, logging will only be
performed when the channel is tripped.
