Select the number “5” to irreversibly reset the counter.
The time it takes to update the measurement saved in the internal memory
is 15 minutes.
Values available for insertion with the CT: 60-100-250 -600-800-1000,
4 hyphens indicate a direct insertion up to 25A.

1If you briefly press on the front button, the letter P and the measure-
mentof active power absorbed by the load in kW will appear,flashing
alternately.
2If you press the button again, or after 2 minutes of inactivity, the display-
returned to the fixed view of the energy counter.

Displaying and saving minimum and maximum peak values
The peak values recorded (minimum and maximum) are saved in the in-
strument’s nonvolatile memory, and are available after any power failure.
You can reset the peak values by means of the corresponding RES com-
mand in the programming menu.
When you change the value of the CT the maximum and minimum alarm
threshold are automatically disabled.
2. AMTD-1-R / AMTD-2-R / VLMD-1-2-R functions
1When you briefly press the front button, the word Lo and the minimum
value measured appear alternately.
2If you press the button again, the word Hi appears with the maximum
value measured.
3Press the button again to return to normal view.

Maximum and minimum relay operation
When the measurement exceeds the threshold value, the relay changes state
and the alarm is tripped after a programmable delay dLY, which appears on
the display alternately with the normal instantaneous measurement.
ALL [ALarm Low] indicates that the minimum threshold has been exceeded
ALH [ALarm High] indicate that the maximum threshold has been exceeded
Even in alarm conditions, pressing the button briefly enables you to view
the minimum and maximum values.
The alarm stops when the measurement returns within the threshold in-
cluding the value of the hysteresis.
Alarm enabling logic
The output from the relay is an open contact type. You can program the
configuration of the relay:
n0 [normally Open] the contact is open when the relay is not energized.
nC [normally Closed] the contact is closed when the relay is not energized.
State of device nO (default) Positive safety nC
