(equal to the number of interposed repeaters plus 1). Read-only parameter if the
instrument is connected to a base unit.
5)
RF_OFF_LINE: enables or disables the RF stage of the data logger. Select NO to
activate the RF stage. Activation or deactivation of the RF stage can be done also
through the connection button.
6)
EXIT: returns to the main menu.
4) THLD_MENU (alarm thresholds)
1)
Quantity 1_DOWN_THLD: lower alarm threshold of quantity 1. The type of quan-
tity depends on the data logger model.
2)
Quantity 1_UP_THLD: higher alarm threshold of quantity 1. The type of quantity
depends on the data logger model.
3)

4)
Quantity n_DOWN_THLD: lower alarm threshold of quantity n. The type of quan-
tity depends on the data logger model.
5)
Quantity n_UP_THLD: higher alarm threshold of quantity n. The type of quantity
depends on the data logger model.
6)
THLD_ALRM: enables or disables the buzzer when measurement thresholds are
exceeded.
7)
EXIT: returns to the main menu.
5) HYST_MENU (hysteresis of the alarm thresholds)
1)
Quantity 1_HYST%: hysteresis of the alarm thresholds of quantity 1. The type of
quantity depends on the data logger model.
2)
…
3)
Quantity n_HYST%: hysteresis of the alarm thresholds of quantity n. The type of
quantity depends on the data logger model.
4)
EXIT: returns to the main menu.
The width of the hysteresis is a percentage (0 ... 100%) of the difference between the two
alarm thresholds.
For example, if Hysteresis=2%, Lower threshold=10 °C and Upper threshold=60 °C, the
hysteresis is (60-10)x2/100= 1 °C:
