(*) With a passive sensor output (open collector, relay contacts, switch contacts
etc.) the maximum input frequency is limited to 1000Hz by the 10nF capacitor
on the input.

7.2.3 Auxiliary voltage output : V-Out

Voltage:
Current:
Note: V-Out is active only when the PC-logger is "awake".
When off line recordings with long sampling intervals are in progress, the
"2100" falls asleep between samplings. This means that power via V-Out is
switched on a few seconds before the sample is taken and then switched off
again as the "2100" goes back to sleep.

INTERNAL DATA STORAGE CAPACITY

The PC-logger 2100 can store in excess of 112 000 values (off-line).
The data RAM is backed up by a lithium battery that will retain data in case of
power failure.
Lithium battery life is 10 years.
