Command Description
ARD1 Reads the alarm activation delay value
AWD2nnn Sets the alarm deactivation delay to nnn seconds (0… 600 s)
Default: 0
ARD2 Reads the alarm deactivation delay value
(*) The thresholds and hysteresis values are considered in the unit of measurement set in
the instrument. The value must be written without the decimal point, even if it is not an
integer value (e.g., to set thresholds 1 to +1.500, write AWT1+1500). Leading zeros can
be omitted (e.g., to set thresholds 1 to +0.050, write AWT1+50).
To exit the configuration mode after sending the CAL START command, send the CAL
END command (the instrument automatically exits the configuration mode after 5
minutes from the last command sent).

ONFIGURATION VIA THE INTERNAL BUTTONS
The configuration set with the internal buttons is used by the instrument only if the
dip switch 1 is ON.
The upper button B1 allows scrolling the available operating parameters, while the
lower button B2 allows changing the setting of the selected parameter.
The function of a button depends on whether it is short or long pressed. To short
press a button, hold it down for about 1 second, until the power LED turns off. To long
press a button, hold it down for at least 3 seconds, until the power LED turns off and
then turns on again.
Long press the upper button
B1 to enter the menu. Inside the menu, long press B1 to
scroll the available parameters. Below is the sequence of the operating parameters (in
brackets the indication that appears on the display) with the possible set-tings for
non-numerical parameters:
•
Relay operating mode (SECU):
o
Negative (NEG): NC contact is closed if no alarm, NO contact is closed if in alarm
o
Positive (POS): NO contact is closed if no alarm, NC contact is closed if in alarm
•
Buzzer activation (BEEP):
o
OFF: buzzer disabled
o
ON: buzzer enabled
• Alarm activation
(ALAR):
o
OFF: alarm disabled
o
ON: alarm enabled
• Alarm operating mode
(EDGE):
o
Above threshold (RISE): alarm is on if measurement is greater than threshold 1
o
Below threshold (FALL): alarm is on if measurement is less than threshold 1
o
Outside thresholds (OUTS): alarm is on if measurement is less than threshold 1
or greater than threshold 2
•
Threshold 1 (THR1): Value of the threshold for above (RISE) and below (FALL)
alarm operating modes; value of the lower threshold for outside thresholds (OUTS)
alarm operating mode (OUTS).
•
Threshold 2 (THR2): Value of the upper threshold for outside thresholds (OUTS)
alarm operating mode. The parameter appears only if the alarm operating mode
