7) Alarm time delay
1)
Quantity 1 alarm delay: delay for alarm activation of quantity 1. The type of
quantity depends on the data logger model.
2)
…
3)
Quantity n alarm delay: delay for alarm activation of quantity n. The type of
quantity depends on the data logger model.
4)
Exit: returns to the main menu.
If the measured value drops below the lower threshold or exceeds the upper threshold, the
alarm is generated after the time set. The alarm is generated immediately if 0 is set. If the
alarm condition ends before the delay time is elapsed, the alarm is not generated.
8) Unit measures
1)
Quantity 1: measurement unit of quantity 1. The type of quantity depends on the
data logger model.
2)
…
3)
Quantity n: measurement unit of quantity n. The type of quantity depends on the
data logger model.
4)
Exit: returns to the main menu.
Note: in the HD35EDH model, only the temperature measurement unit is available. Meas-
urement units for the other quantities are configurable in the menus for the setting of
channels Ch 1, Ch 2 e Ch 3.
Note: the unit of measurement is changed only on the LCD; the data are always sent in
the unit of measurement set in the base unit.
9) Logging
1)
Start/stop log: enables or disables logging.
2)
Logging mode: choice between cyclical management (the new data overwrite the
old ones when the memory is full) or non-cyclical management (logging stops when
the memory is full) of the data logger memory.
3)
Log/RF Tx interval: choice of logging and RF transmission interval (the two inter-
vals coincide). If it is higher than the measuring interval, the average of the meas-
urements acquired during the interval will be stored.
4)
Measure interval: choice of the measurements acquisition interval. It is forced to
the value RF log/Tx interval if a higher value is set.
5)
Log erase: deletes all stored measurements from the data logger memory.
6)
Exit: returns to the main menu.
